At the far western end of Enoshima Island, beyond the busy shopping street, hilltop shrines and observation lighthouse, a narrow coastal walkway leads into two ancient sea caves.
Inside, the sound of the ocean fades behind dark stone walls. Passages carved by centuries of wave erosion lead towards Buddhist statues, religious objects and a legendary dragon that has become part of Enoshima’s identity.
These are the Enoshima Iwaya Caves, one of the island’s most unusual attractions and a reminder that Enoshima was a place of pilgrimage long before it became a popular seaside destination.
Visiting the caves offers something quite different from the panoramic views at Sea Candle or the traditional architecture of Enoshima Shrine. The first cave is associated with Buddhist history and candlelit exploration, while the second brings the island’s famous dragon legend to life.
However, there is an important detail that many visitors underestimate.
Getting to the Iwaya Caves is more demanding than exploring the caves themselves.
The caves are located beyond the main sightseeing area, and reaching them on foot involves a substantial walk across the island, including steep stairways and changes in elevation.
Fortunately, there is an alternative when the weather cooperates: the Benten-maru sightseeing boat connects the bridge area with the rocky coast near the caves.
This guide explains everything you need to know about visiting the Enoshima Iwaya Caves in 2026, including current admission prices, opening hours, the best walking route, boat fares, what you will see inside and whether the experience is worth the effort.

Our recommendation: Visit the Iwaya Caves as part of a half-day or full-day exploration of Enoshima. The caves themselves are relatively small, but the combination of coastal scenery, religious history and the nearby Chigogafuchi rock formations makes the journey worthwhile.
If you want to see the shrines, Sea Candle and caves in one visit, allow at least three to four hours on the island, and preferably longer if you enjoy photography or plan to stop for lunch.
Our 👉 Enoshima Day Trip from Tokyo explains how to build these attractions into a realistic itinerary.
Are the Enoshima Iwaya Caves Worth Visiting?
Yes, particularly if you enjoy Japanese history, unusual natural attractions and exploring beyond the busiest tourist areas.
The Iwaya Caves are not enormous. You will not spend hours walking through a vast underground network, and there are no elaborate cave formations comparable to Japan’s largest limestone caverns.
Instead, the appeal comes from the combination of geology, religious tradition and atmosphere.
The caves were gradually formed by waves eroding the rock along Enoshima’s coastline. Over many centuries, they became associated with spiritual practices and the worship of Benzaiten, a deity closely connected with the island’s history.
Visitors can now explore two separate passages, with displays explaining the caves’ religious significance.
The first cave contains historical exhibits and has traditionally offered a candlelit experience, while the second is associated with a dragon believed in local legend to have lived around Enoshima.
At just ¥500 for adult admission, the ticket price is unlikely to be the deciding factor for most travellers.
The greater consideration is whether you want to walk across the island to reach them.
Why We Recommend Visiting
What makes Iwaya worthwhile is not simply the caves themselves.
The approach takes you through a different part of Enoshima, away from the busiest shopping areas and into a landscape of steep slopes, traditional religious sites and dramatic coastal rock formations.
Near the entrance, Chigogafuchi provides expansive views of the sea and surrounding cliffs.
On a clear day, Mount Fuji may also be visible across Sagami Bay.
The transition from an open, windswept coastline into the dimly illuminated caves gives the experience much of its character.
For travellers interested in Enoshima’s history, the caves are also closely connected with the religious traditions introduced at Enoshima Shrine.
Rather than visiting only the modern observation tower, you gain a better understanding of how the island developed as a sacred destination.
When Would We Skip the Caves?
The most important reason to skip Iwaya is limited time.
If you only have 90 minutes or two hours on Enoshima, travelling all the way to the far western end may leave very little opportunity to appreciate the shrine or Sea Candle.
Visitors who have difficulty with stairs should also think carefully before attempting the journey.
The approach involves considerable changes in elevation, and the boat cannot be relied upon as guaranteed transport.
Families with strollers may find the route particularly awkward.
Finally, anyone expecting a vast cave system may find the experience brief.
Our verdict: The Iwaya Caves are worth visiting as part of a wider Enoshima sightseeing day. The walk and coastal scenery are important parts of the experience, so allow enough time to enjoy them instead of treating the caves as a quick detour.
What Is Inside the Enoshima Iwaya Caves?
The attraction consists of two separate sea caves, known as the First Iwaya Cave and Second Iwaya Cave.
Both were formed by the action of the sea against the island’s rocky coastline, but each has developed a different cultural identity.
The first is larger and closely associated with religious history.
The second is shorter and focuses on Enoshima’s dragon legend.
A standard admission ticket includes both caves.
First Iwaya Cave: Candlelight and Buddhist History
The First Iwaya Cave extends approximately 152 metres into the rock.
It is the larger of the two caves and contains the most extensive historical displays.
As you enter, the atmosphere changes quickly.
The open coastal scenery disappears, the temperature feels cooler and the passage becomes enclosed by natural rock walls.
Walkways and lighting make the cave accessible to ordinary visitors, although there are lower sections where taller people may need to duck.
The first cave has traditionally offered visitors a candle to carry through part of the passage.
When this service is operating, the small flame creates a distinctive atmosphere and illuminates the surrounding rock.
This is more than a decorative feature.
Enoshima’s caves have long been associated with religious pilgrimage, and candlelight provides a reminder of how people may have experienced these passages before modern electric lighting.
However, the candle service is not guaranteed.
During busy periods or when operational conditions require it, staff may suspend candle distribution.
You can still explore the illuminated cave without carrying a candle.
Along the passage are historical exhibits, stone religious figures and explanations of Enoshima’s cultural traditions.
Near the deeper sections, the passage divides into two branches.
One is connected with legends about Mount Fuji, while the other is traditionally regarded as a sacred location associated with the origins of Enoshima Shrine.
The experience is relatively short, but visitors who enjoy historic religious sites should find it interesting.
The Legend of the Cave Connecting to Mount Fuji
One of the most unusual stories associated with the First Iwaya Cave is the belief that its deepest passage connects underground to Mount Fuji.
According to local tradition, a passage extends towards the Narusawa Ice Cave near the mountain.
This should be understood as folklore, not an established geological connection.
There is no visitor route through Enoshima that takes you underground to Mount Fuji.
Nevertheless, the legend reflects the spiritual importance attached to both locations over centuries.
Mount Fuji is one of Japan’s most sacred mountains, and Enoshima has its own longstanding religious traditions.
The idea of an underground connection gives the cave an additional layer of mystery.
It is also a reminder that caves were not always approached as recreational attractions.
In the past, places like Iwaya were associated with religious practice, legends and journeys of spiritual significance.
Second Iwaya Cave: Enoshima’s Dragon Legend
The Second Iwaya Cave is approximately 56 metres deep.
It is shorter than the first, but many visitors remember it because of its dramatic dragon-themed display.
Enoshima has a famous legend involving a five-headed dragon, known as Gozuryu, and the goddess Benzaiten.
According to the story, the dragon once caused suffering in the surrounding region.
When Benzaiten appeared, the dragon fell in love with her. The goddess rejected his advances until he changed his behaviour and promised to protect the local people.
The dragon eventually became a guardian figure associated with the area.
Different versions of the legend contain slightly different details, but the story remains deeply connected with Enoshima.
Inside the second cave, visitors encounter a dragon display using light and sound effects.
The atmosphere is more theatrical than in the first cave, making it particularly memorable for families and visitors interested in Japanese folklore.
However, do not expect an elaborate theme-park attraction.
The cave remains small, and the display is one part of a short visit.
Which Iwaya Cave Is Better?
If you are interested in history, Buddhism and Enoshima’s religious past, the First Cave is more rewarding.
If you enjoy mythology and visual displays, the Second Cave may be the more memorable experience.
However, there is little reason to choose between them.
Both are included in the same admission ticket, and visiting the two caves is manageable in a single short visit.
Why Are the Iwaya Caves Historically Important?
The Iwaya Caves are regarded as one of the places associated with the origins of religious worship on Enoshima.
Long before visitors came to the island for its beaches and observation tower, Enoshima attracted pilgrims who believed the caves and surrounding landscape possessed spiritual significance.
The island became particularly associated with Benzaiten, a deity connected with music, wisdom, prosperity and water.
During different periods of Japanese history, Enoshima’s religious traditions combined elements of Buddhism and the worship of local deities.
The caves were an important part of this spiritual landscape.
According to traditional accounts, prominent Buddhist figures, including Kobo Daishi, also known as Kukai, and Nichiren, visited or practised religious disciplines here.
Another tradition associates the caves with Minamoto no Yoritomo, the founder of the Kamakura shogunate, who is said to have prayed here for military success in 1182.
These stories form part of the site’s religious history and should not all be treated as independently confirmed events.
The distinction is important because the caves’ value comes from understanding both their physical formation and the beliefs that developed around them.
Today, the displays help explain the relationship between the natural landscape and centuries of religious practice.
For more information about the island’s shrines and their significance, read our 👉 Enoshima Shrine Guide: Three Shrines, Walking Route & What to See.
Enoshima Iwaya Cave Ticket Prices in 2026
Admission to the caves is relatively inexpensive.
The current prices published by the Fujisawa tourism authorities are:
| Visitor | Admission |
|---|---|
| Adults and junior high school students or older | ¥500 |
| Elementary school students | ¥200 |
| Eligible visitors with recognised disability documentation | Free under applicable conditions |
| One accompanying person for eligible visitors | Free under applicable conditions |
Groups of 20 or more may qualify for a 20% discount.
A standard ticket includes both cave sections.
You do not need to purchase separate admission for the dragon cave.
Do You Need to Book Iwaya Cave Tickets?
For ordinary individual visits, advance reservations are not generally necessary.
You can purchase admission at the cave entrance when the attraction is operating.
However, access may be restricted or suspended due to dangerous weather, high waves or other safety concerns.
If Iwaya is your main reason for travelling to Enoshima, check the daily operating status before committing to the longer walk.
Is There a Combination Ticket for Iwaya Cave and Sea Candle?
Yes, and this is where some visitors can save money.
The operator sells several combination tickets that include the Iwaya Caves and other Enoshima attractions.
| Ticket | Adult Price | Includes |
|---|---|---|
| Iwaya Cave only | ¥500 | Both caves |
| Iwaya + Sea Candle | ¥1,110 | Both caves and observation tower |
| Enoshima 1day | ¥1,550 | Iwaya, Sea Candle and full uphill Escar |
| Enoshima 1day + Night | ¥1,950 | Above attractions plus paid evening garden access when applicable |
The ¥1,110 Iwaya and Sea Candle combination does not include the Escar.
This is an important distinction if you want to avoid part of Enoshima’s uphill climb.
The ¥1,550 Enoshima 1day pass includes the Escar, Sea Candle and Iwaya Caves, making it particularly useful for visitors who intend to see all three attractions.
There are additional ticket products that combine Enoshima attractions with the aquarium, but these should not be confused with the standard Enoshima 1day pass.
Which Ticket Offers the Best Value?
For a visit to the caves alone, buy the ¥500 admission ticket.
If you also want to visit the Sea Candle, the ¥1,110 combination costs less than purchasing both admissions separately.
The two individual admissions total ¥1,300.
For visitors planning to use the Escar as well, the ¥1,550 Enoshima 1day pass is worth considering.
Buying the full Escar, Sea Candle and Iwaya admissions separately would cost ¥1,800.
The combination therefore provides a modest saving while simplifying ticket purchases.
However, if you are comfortable walking and do not particularly want to visit the observation tower, there is no reason to purchase a more expensive pass.
For the complete Sea Candle ticket comparison, see our 👉 Enoshima Sea Candle: Tickets, Sunset Views & Is It Worth Visiting?.
Enoshima Iwaya Cave Opening Hours in 2026
The caves operate on a seasonal schedule.
As of October 2026, the officially announced opening period is:
9am–5pm, with 5pm listed as the final admission time.
During warmer months and selected events, the caves may remain open later.
In 2026, the extended summer schedule ran from 25 April to 30 September, with admission available until 6pm.
| Period | Published Admission Schedule |
|---|---|
| From 1 October 2026 | 9am–5pm, final admission |
| 25 April–30 September 2026 | 9am–6pm, final admission |
| Severe weather or dangerous sea conditions | Temporary closure or changed hours possible |
Although the operator publishes a final admission time, we would not recommend arriving at the caves just before it.
The caves are at the far end of a hilly island, and leaving enough time for the return journey is important.
For a relaxed visit, aim to arrive well before 4pm during the current autumn and winter schedule.
Are the Iwaya Caves Open Every Day?
The caves normally operate throughout the year.
However, their coastal location makes them more vulnerable to adverse conditions than many ordinary tourist attractions.
Temporary closures can occur because of typhoons, high waves, tsunami warnings or other safety concerns.
The caves may also change their schedule for special events and maintenance.
Before travelling, check the current operating information rather than relying on general opening hours from an older travel article.
Are the Caves Open at Night?
Normally, no.
The Iwaya Caves should not be treated as a late-night attraction simply because Sea Candle and Samuel Cocking Garden remain open after sunset.
During the 2025–2026 winter illumination season, Iwaya’s special illumination display was available during daytime cave opening hours, generally 9am–5pm.
The precise arrangements for the 2026–2027 winter event should be confirmed once the organiser publishes the full programme.
If you are planning to see the caves and the winter illuminations on the same day, visit the caves first and save Samuel Cocking Garden for the evening.
Our 👉 Enoshima Illuminations 2026–2027 Guide covers the confirmed winter event dates and ticket arrangements.
How to Get to Enoshima Iwaya Cave
Reaching the Iwaya Caves requires more planning than visiting Enoshima’s main shopping street or lower shrine buildings.
The caves are located on the island’s western coast, beyond the main sightseeing area.
Visitors can reach them by walking across Enoshima or by using the Benten-maru pleasure boat when it is operating.
Walking from Katase-Enoshima Station
Katase-Enoshima Station on the Odakyu Line is one of the most convenient starting points for travellers coming directly from Tokyo.
From the station, walk towards Enoshima Bentenbashi, the bridge connecting the mainland with the island.
Cross the bridge and continue towards Nakamise Street, the main shopping street near the island entrance.
From there, the route climbs past Enoshima Shrine towards the upper island.
You can use the Enoshima Escar to avoid some of the uphill stairs or continue on foot.
After reaching the upper part of Enoshima, follow the signs towards Okutsumiya Shrine and Chigogafuchi.
The route then descends towards the western coastline.
Near the rocky shore, continue along the established walkway to the entrance of the Iwaya Caves.
Allow approximately 40–60 minutes from Katase-Enoshima Station if walking directly, with considerably longer if you stop at the shrines, viewpoints or shops.
The most important thing to understand is that the route is not flat.
Even if you use the Escar for the earlier uphill section, the western side of the island involves additional stairs and changes in elevation.
Walking from Enoshima Station on the Enoden
Enoshima Station is convenient for travellers arriving from Kamakura.
The station is located farther from the bridge than Katase-Enoshima, but the route is straightforward.
Walk towards the coast, cross Bentenbashi and continue along the same island path towards the caves.
Allow approximately 45–65 minutes for a direct journey, depending on your pace.
If you are combining Kamakura and Enoshima in one day, the Enoden is an enjoyable way to reach the area.
The railway’s coastal section passes beaches and neighbourhoods with views across Sagami Bay.
For stops worth visiting along the way, see our 👉 Enoden Guide: Best Stops Between Kamakura and Enoshima.
Walking from Shonan-Enoshima Station
The Shonan Monorail connects Ofuna with Shonan-Enoshima.
From the terminal station, walk towards the coastline and continue across the bridge.
The island route is the same once you reach Nakamise Street.
Allow approximately 45–65 minutes to reach the caves, depending on your walking speed and stops.
The monorail is worth considering if you are arriving through Ofuna or want to experience Japan’s unusual suspended railway.
Our 👉 Enoden vs Shonan Monorail Guide explains the differences.
Can You Take a Boat to the Enoshima Iwaya Caves?
Yes.
The Benten-maru pleasure boat connects the Enoshima Bentenbashi area with Chigogafuchi, close to the cave entrance.
The journey takes approximately six minutes and provides a different perspective of the island’s coastline.
Instead of walking over the hill, you travel by sea towards the rocky western shore.
The boat is particularly useful for visitors who want to reduce the amount of walking.
However, it is important not to confuse the Benten-maru with a frequent public ferry.
This is a weather-dependent sightseeing boat, and its operating schedule is limited.
Benten-maru Boat Prices in 2026
The current official one-way fares are:
| Passenger | Fare |
|---|---|
| Adults, junior high school age and older | ¥500 |
| Children aged 6 and older | ¥200 |
| Children aged 5 and younger | Free |
Payment is cash only.
The boat connects Enoshima Bentenbashi with the Chigogafuchi landing area.
From Chigogafuchi, follow the walkway towards the Iwaya Cave entrance.
What Time Does Benten-maru Operate?
The official tourism association publishes approximate operating periods rather than a fixed timetable of guaranteed departures.
| Period | Typical Operating Window |
|---|---|
| Weekdays when scheduled | Approximately 11am–2:30pm |
| Weekends and public holidays | Approximately 10:30am–2:30pm |
| Weekdays in December, January and February | Normally no service |
| Strong winds, high waves or unsafe tides | Service may be suspended |
The final operating decision is generally made around 10:30am on the day.
Even after operations begin, the service can be suspended if conditions deteriorate.
This means the boat is most useful when you can remain flexible.
Is the Boat Worth Taking?
Yes, particularly if you want to avoid walking across the island in both directions.
One excellent option is to explore the shrines and upper island on foot, continue down towards Iwaya and then take the boat back from Chigogafuchi.
This avoids repeating the uphill return route and gives you attractive views of Enoshima from the water.
However, the boat generally finishes operating well before the caves close.
If you arrive at Iwaya late in the afternoon, you should not expect to find a boat available for the return journey.
Should You Take the Boat First or Last?
Both approaches can work.
Taking the boat towards the caves first allows you to explore the western coastline early in the day and then walk back across Enoshima.
Taking it at the end of your visit reduces the need to climb back over the island after exploring the caves.
For most first-time visitors, we prefer walking across Enoshima towards the caves because it allows you to see the island’s shrines and viewpoints in a natural sequence.
Then, if the boat is confirmed to be operating and you reach Chigogafuchi before its final departures, you can use it for the return.
However, never make the boat your only viable return plan.
If you cannot comfortably complete the walking route without it, check the operating conditions carefully before proceeding to the caves.
Chigogafuchi: The Coastal Viewpoint You Should Not Miss
One of the highlights of visiting the Iwaya Caves is the nearby Chigogafuchi rock platform.
Located along Enoshima’s western coastline, Chigogafuchi is known for its dramatic rock formations and views across Sagami Bay.
The broad rocky shoreline was shaped by geological processes and coastal erosion, creating an exposed landscape very different from the island’s wooded upper areas.
On clear days, the views can extend towards Mount Fuji and the surrounding coastline.
This makes Chigogafuchi one of the best places to appreciate Enoshima’s natural setting.
The atmosphere can be particularly beautiful in the late afternoon, when the sunlight falls across the rocks and water.
However, the coast is exposed.
Waves can reach parts of the rocky platform, and surfaces may become slippery.
Do not approach the water’s edge during rough conditions, and follow any local restrictions or warnings.
You do not need to venture onto exposed rock surfaces to enjoy the scenery.
The established paths and viewing areas provide worthwhile perspectives without taking unnecessary risks.
Is Chigogafuchi Better Than the Caves?
For visitors who mainly enjoy landscape photography, Chigogafuchi may actually be the more memorable attraction.
The combination of the open sea, steep cliffs and rocky shoreline creates a dramatic scene.
The caves are more appealing for those interested in history, geology and folklore.
However, the two experiences work particularly well together.
Because they are so close to each other, we recommend treating them as one combined destination.
Allow at least 15–30 minutes around the coastal area in addition to the cave visit, particularly if the weather is clear.
For more regional viewpoints, see our 👉 Best Mount Fuji Views from Enoshima and Kamakura.
How Difficult Is the Walk to Iwaya Cave?
The walk is moderately demanding because Enoshima is a hilly island.
The difficulty does not come from a long wilderness trail.
Instead, it comes from repeatedly climbing and descending stairs and walking across uneven or sloping surfaces.
The main route is developed for sightseeing, but it still requires a reasonable level of mobility.
The most tiring section for some visitors is the journey back from the caves.
After reaching the western coastline, you may need to climb uphill again before returning towards the island entrance.
This is why the Benten-maru boat can be so appealing when available.
Does the Enoshima Escar Help?
Yes, but only for part of the journey.
The Escar is a series of escalators that helps visitors climb from the lower shrine area towards the island’s upper section.
It reduces the uphill effort and can save energy during a longer sightseeing day.
However, the Escar only operates uphill.
It does not provide downhill transport, and it does not take visitors directly to Iwaya.
The route beyond the upper island still involves stairs and changes in elevation.
For more information about the escalators and their ticket combinations, see our 👉 Enoshima Sea Candle Guide.
Can You Visit Iwaya Cave With a Stroller?
A stroller is not practical for the full walking route.
The approach involves numerous steps, including sections near the western coast.
Although the Benten-maru boat can reduce the distance, large or non-folding strollers may not be accepted on board.
Visitors travelling with young children should consider whether a suitable child carrier would be more practical.
Is Iwaya Cave Wheelchair Accessible?
The full route to Iwaya is not straightforward for wheelchair users.
The island’s stairways, steep changes in elevation and the approach to the caves create significant barriers.
The boat should not be assumed to offer a fully accessible alternative.
Even within the caves, narrow passages and confined areas make access more challenging.
Visitors who require step-free travel should contact the tourism authorities before planning a visit.
For a gentler family itinerary, see our 👉 Enoshima With Kids: Aquarium, Island Walks & Easy Family Route.
Are the Iwaya Caves Suitable for Children?
The caves can be enjoyable for children, particularly those interested in dragons, unusual natural formations and exploring enclosed spaces.
The second cave’s dragon display may be especially memorable.
However, parents should consider both the approach and the cave conditions.
The walk across Enoshima can be tiring for younger children, especially during summer.
Inside the caves, some sections have lower ceilings and narrow passages.
The lighting is also deliberately subdued in places.
Children who are uncomfortable with dark or confined environments may prefer a shorter visit.
For older children who enjoy exploring, the caves can be an interesting addition to a family day on Enoshima.
The key is to avoid turning the entire visit into an exhausting walk.
Arrive early, take breaks and consider whether the boat is operating.
If you want to combine the caves with another family-friendly attraction, the nearby New Enoshima Aquarium is a popular option on the mainland.
Our 👉 Enoshima Aquarium Guide explains its main attractions and how to plan a visit.
How Long Do You Need at Enoshima Iwaya Cave?
The caves themselves are relatively quick to explore.
Most visitors should allow around 20–40 minutes inside the two cave sections.
Those who enjoy reading historical information or taking photographs may want slightly longer.
However, the full excursion takes considerably more time.
| Part of the Visit | Suggested Time |
|---|---|
| Walk from Katase-Enoshima Station to Iwaya | 40–60 minutes |
| Explore both caves | 20–40 minutes |
| Enjoy Chigogafuchi coastal views | 15–30 minutes |
| Return across the island on foot | 40–60 minutes |
| Optional shrine and Sea Candle stops | Additional time |
The walk estimates assume a reasonably direct journey without long sightseeing stops.
For a complete Enoshima visit including shrines and Sea Candle, allow a half-day or longer.
If you are travelling from Tokyo, the caves are best included in a wider itinerary rather than treated as a standalone excursion.
Best Enoshima Iwaya Cave Half-Day Itinerary
For most first-time visitors, the best route is to explore the island from east to west.
This lets you enjoy the main shrine areas, upper viewpoints and caves in a logical sequence.
9:30am — Arrive at Katase-Enoshima Station
Begin at the Odakyu railway station and walk towards the coast.
Cross Enoshima Bentenbashi and enjoy the views towards the island.
The bridge is a good introduction to the coastal scenery.
10am — Explore Nakamise Street and Enoshima Shrine
Walk through the shopping street and continue towards the shrine.
Enoshima Shrine has three principal shrine areas, each located at different points across the island.
You do not need to visit every building in detail, but exploring the route helps you appreciate the island’s religious history before reaching the caves.
11am — Visit Samuel Cocking Garden and Sea Candle
Continue towards the upper part of Enoshima.
If the weather is clear, consider going up Sea Candle for panoramic views across Sagami Bay.
The garden is free during ordinary daytime hours, while tower admission is separate unless you have a combination ticket.
If time is limited, you can skip the tower and continue towards Iwaya.
Noon — Continue Towards Okutsumiya and the Western Coast
Follow the island paths towards Okutsumiya Shrine.
From there, descend towards Chigogafuchi.
This section provides a very different atmosphere from the main shopping street.
The landscape becomes more rugged as you approach the coast.
12:30pm — Explore Chigogafuchi and Iwaya Cave
Spend some time enjoying the coastal views before entering the caves.
Allow around 30 minutes to explore both cave sections, plus additional time for photographs.
1:15pm — Return or Use Benten-maru
If the boat is operating, you may be able to return towards the bridge by sea.
Otherwise, follow the walking route back across the island.
You can stop for lunch or refreshments along the way.
This is a flexible itinerary rather than a fixed schedule.
During busy holiday periods or when travelling with children, allow additional time for the walking sections and attraction queues.
Can You Visit Iwaya Cave and Kamakura in One Day?
Yes, but it requires sensible priorities.
Kamakura and Enoshima are close enough to combine in a day trip from Tokyo, and the Enoden railway provides a convenient connection between them.
A practical approach is to spend the morning visiting one or two Kamakura attractions before travelling to Enoshima.
For example, you could see the Great Buddha and Hase-dera, then take the Enoden towards Enoshima.
However, including Iwaya means committing to the longer island route.
It is not realistic to explore central Kamakura, several major temples, the entire Enoshima coastline, Sea Candle and the caves thoroughly in just a few hours.
If Iwaya is a priority, reduce the number of Kamakura stops.
Alternatively, divide Kamakura and Enoshima across two days if your schedule allows.
Our 👉 Kamakura & Enoshima One-Day Itinerary provides a route designed to avoid unnecessary backtracking.
Best Time of Year to Visit Enoshima Iwaya Caves
The caves can be visited throughout the year, subject to operational conditions.
However, each season changes the experience of walking across the island.
Spring: Comfortable Weather for the Island Walk
Spring is one of the best times to visit.
Temperatures are generally pleasant for walking, and the island’s vegetation becomes increasingly green.
The coastal views are attractive, and the weather is often more comfortable than in midsummer.
However, weekends and major holidays can be busy.
Golden Week in late April and early May is particularly popular for domestic travel.
Summer: Cool Cave Interiors but Hot Walking Conditions
The cave interiors remain noticeably cooler than the outside air.
That can make the attraction appealing during Japan’s humid summer months.
However, reaching Iwaya requires significant walking, including exposed sections where the heat can feel intense.
Plan an early start, carry water and allow time for breaks.
Summer is also when typhoons and unsettled sea conditions can affect cave openings and boat operations.
Do not assume the attraction will operate normally during severe weather.
Autumn: One of the Best Seasons to Visit
Autumn is an excellent time for exploring Enoshima on foot.
As temperatures become more comfortable, walking between the shrines, Sea Candle and western coastline becomes more enjoyable.
Clear days may also offer attractive long-distance views across Sagami Bay.
If you are visiting in October or early November, Enoshima’s autumn candle event may provide an evening activity after the caves have closed.
However, the caves and the garden’s evening displays have separate schedules.
Winter: Clear Coastal Views and Fewer Daylight Hours
Winter can be especially rewarding for photography.
Cooler, drier conditions often improve the chances of seeing Mount Fuji across the water.
However, daylight hours are short, and the exposed western coast can feel cold and windy.
Plan to reach Iwaya during the earlier part of the day.
The Benten-maru boat also has more limited winter operations, particularly on weekdays in December, January and February.
If you are visiting during the winter illumination festival, make the caves your daytime attraction and save Sea Candle for after sunset.
What to Wear and Bring
Comfortable walking shoes are the most important thing to bring to the Iwaya Caves.
The journey across Enoshima includes stairs, stone pathways and exposed coastal areas.
Shoes with good grip are preferable to sandals or footwear that becomes slippery on wet surfaces.
Although the cave interiors are cool, you do not need specialist caving equipment.
The attraction has developed visitor walkways and lighting.
However, taller visitors should be prepared to duck beneath lower rock ceilings.
During winter, bring an extra layer for the exposed coastline.
During summer, carry water and protect yourself from the sun while walking across the island.
A charged phone is useful for navigation and checking the boat’s operating status, while a little cash is necessary if you plan to use Benten-maru.
Photography Tips for Enoshima Iwaya Caves
The caves offer interesting photographic opportunities, but low light can make photography difficult.
Rather than relying on flash, try to make use of the existing cave lighting where photography is permitted.
The natural textures of the rock walls and illuminated passageways can create atmospheric images.
However, follow staff instructions and avoid blocking narrow sections while taking photographs.
The dragon display may also be difficult to photograph because of the lighting effects.
Outside the caves, Chigogafuchi offers a completely different photographic experience.
The rocky coastline, waves and distant mountains are particularly attractive on clear days.
For landscape photography, you may find that the views outside the caves are even more rewarding than the cave interiors.
Do not approach dangerous rock edges to obtain a better photograph, especially when waves are strong.

The ticket covers both cave sections.
What are the Iwaya Cave opening hours?
As of October 2026, the announced schedule is 9am–5pm, with 5pm listed as final admission.
Summer and special events may have different hours, and severe weather can cause closures.
Are the Enoshima Iwaya Caves worth visiting?
Yes, particularly if you enjoy unusual natural attractions, Japanese religious history and folklore.
The caves are relatively small, but they combine well with the coastal scenery around Chigogafuchi.
How long does it take to visit Iwaya Cave?
Allow around 20–40 minutes for the two caves themselves.
However, reaching the caves on foot from the mainland can take approximately 40–60 minutes each way, depending on your route and pace.
Can you take a boat to Iwaya Cave?
Yes.
The Benten-maru boat connects the Enoshima bridge area with Chigogafuchi, close to the caves.
The journey takes approximately six minutes and costs ¥500 for adults one way.
Service depends on weather and sea conditions.
Does the Benten-maru boat run every day?
No.
The service operates on a limited, weather-dependent schedule.
Weekdays in December, January and February normally have no service, and the boat can also be suspended during rough sea conditions.
Check the day’s operating status before relying on it.
Are there two Iwaya Caves?
Yes.
The First Cave is approximately 152 metres deep and focuses on the site’s religious history.
The Second Cave is approximately 56 metres deep and contains a display associated with Enoshima’s dragon legend.
Do you need to book Iwaya Cave tickets in advance?
No advance reservation is normally necessary for individual visitors.
Tickets can be purchased at the cave entrance while the attraction is operating.
Can you use the Enoshima 1day pass at Iwaya Cave?
Yes.
The Enoshima 1day pass includes the Iwaya Caves, Sea Candle and the uphill Escar.
The current adult price is ¥1,550.
Is Iwaya Cave suitable for young children?
The caves can be enjoyable for children, but the long approach and numerous stairs can be tiring.
Some cave passages also have low ceilings and subdued lighting.
Younger children should be supervised carefully.
Is Enoshima Iwaya Cave wheelchair accessible?
The full walking route is not reliably step-free, and there are significant accessibility challenges.
Visitors with limited mobility should contact the tourism authorities before travelling.
Can you visit Iwaya Cave and Sea Candle on the same day?
Yes.
The two attractions are located on different parts of Enoshima and can be combined during a half-day or full-day visit.
We recommend visiting the caves before they close and then enjoying Sea Candle later in the afternoon.
Are the Iwaya Caves open during the winter illuminations?
The caves normally continue operating during winter, subject to weather and other restrictions.
However, they generally close earlier than the main illumination displays at Samuel Cocking Garden.
Do not assume they are open late at night.
Is Chigogafuchi worth visiting?
Yes.
Chigogafuchi is one of Enoshima’s most attractive coastal viewpoints, with dramatic rock formations and views across Sagami Bay.
It is located close to the cave entrance and makes the journey more rewarding.
Final Verdict: Should You Visit Enoshima Iwaya Caves in 2026?
The Enoshima Iwaya Caves are a worthwhile attraction for travellers who enjoy discovering the less obvious parts of Japan’s popular sightseeing destinations.
The caves themselves are relatively small, but their combination of natural geology, Buddhist history and Japanese mythology makes them distinctive.
The First Cave offers an atmospheric introduction to Enoshima’s religious past, while the Second Cave brings the island’s dragon legend to life.
Yet the journey is an equally important part of the experience.
Walking beyond the central shrine and Sea Candle area towards Chigogafuchi reveals a more rugged side of Enoshima, with dramatic cliffs and expansive ocean views.
At ¥500 for adult admission, the caves are affordable.
The greater investment is your time and energy.
Our recommendation is to visit Iwaya if you have at least half a day to explore Enoshima comfortably. Combine the caves with Chigogafuchi, the island’s shrines and, if time allows, Sea Candle.
Use the Benten-maru boat if it is operating and fits your schedule, but be prepared to walk the return route.
If you only have a short visit or find steep stairways difficult, prioritise the lower shrine areas and other more accessible attractions instead.
