Eating sushi in Tokyo isn’t difficult.
Eating an elaborate sushi-kaiseki dinner inside one of Japan’s most important museums after the galleries have closed is a little different.
Sushi Kaiseki Okuno (鮨会席 おく乃) opened on September 30, 2026 inside the Gallery of Horyuji Treasures at the Tokyo National Museum in Ueno.
It’s small, just eight counter seats and one private room — and deliberately feels removed from the busy restaurants outside Ueno Station.
Lunch is surprisingly approachable, with the opening menu priced at ¥3,800.
Dinner is a completely different proposition.
The opening dinner course costs ¥25,000 per person, combining sushi with dishes such as crab and caviar, abalone, amadai, kawahagi, wagyu and eel.
So is it worth spending that much on dinner when Tokyo already has hundreds of excellent sushi restaurants?
Possibly.
But we’d choose Okuno for the combination of food and setting, not simply because you’re searching for the best sushi in Tokyo.
Here’s what you actually need to know before booking.
Quick Answer
Sushi Kaiseki Okuno is worth considering if you want a special Japanese dining experience rather than simply a sushi meal.
It’s located on the first floor of the Gallery of Horyuji Treasures at the Tokyo National Museum in Ueno.
There are currently two very different ways to experience it.
The opening lunch costs ¥3,800 including tax and service and centres on fresh bluefin tuna bara-chirashi with several accompanying dishes.
The opening dinner course costs ¥25,000 including tax and service and is a much more elaborate sushi-kaiseki meal.
Lunch runs from 11:00am–2:00pm and walk-ins are possible.
Dinner runs from 5:30pm–10:00pm and is reservation only.
One particularly useful detail: if you have a course reservation for lunch or dinner and follow the entry instructions given when booking, you don’t need to buy a separate museum admission ticket.
Walk into lunch without a reservation, however, and you’ll need normal Tokyo National Museum admission to reach the restaurant.
For most travellers, the ¥3,800 lunch is the easiest recommendation.
For a birthday, anniversary or one special dinner in Tokyo, the ¥25,000 dinner becomes much more interesting.
What Is Sushi Kaiseki Okuno?
Okuno isn’t a normal sushi counter that happens to rent space inside a museum.
The concept deliberately combines sushi and kaiseki cuisine with the surroundings of the Tokyo National Museum.
That distinction matters.
Kaiseki is a multi-course style of Japanese dining built around seasonality, presentation and the progression of dishes rather than simply serving a sequence of nigiri.
At Okuno, sushi sits within that wider meal.
The restaurant describes the experience around seasonal ingredients, Japanese hospitality and the atmosphere of the Gallery of Horyuji Treasures.
That might sound like marketing until you see where you’re eating.
The Setting May Be the Best Reason to Go
Okuno sits inside the Gallery of Horyuji Treasures, one of the most architecturally interesting buildings at the Tokyo National Museum.
The gallery houses more than 300 treasures originally donated to Japan’s Imperial Household by Horyuji Temple in Nara in 1878 before later being transferred to the national government.
The current building opened in 1999.
It was designed by Yoshio Taniguchi, the Japanese architect whose work also included the redesign and expansion of New York’s Museum of Modern Art.
The building uses glass, water, stone and large open spaces to create a noticeably quieter atmosphere than much of central Tokyo.
Okuno continues that idea inside the restaurant.
Shoji screens, washi paper, stone and subdued lighting are used rather than turning the room into another flashy luxury restaurant.
For us, that’s the selling point.
You’re not simply paying ¥25,000 for a plate of expensive ingredients.
You’re paying for a meal that could only really exist here.
Where Is Sushi Kaiseki Okuno?
You’ll find it at:
Gallery of Horyuji Treasures, 1F
Tokyo National Museum
13-9 Ueno Park, Taito-ku, Tokyo
The Tokyo National Museum is in Ueno Park.
From JR Ueno Station, allow roughly ten minutes on foot to reach the museum.
It’s also accessible from Uguisudani, Keisei Ueno and several Tokyo Metro stations.
That makes Okuno relatively easy to work into a day exploring eastern Tokyo.
You could spend the morning around Asakusa, continue to Ueno and the museum, then have lunch at Okuno.
Or make the museum itself the focus and use Okuno as the meal rather than rushing somewhere else afterwards.
Sushi Kaiseki Okuno Lunch: ¥3,800
This is the part of Okuno we think could become particularly interesting for international visitors.
The opening lunch is ¥3,800 including tax and service.
It’s called the Bara Chirashi Jewel Box with Fresh Bluefin Tuna.
Rather than serving only a bowl of chirashi, the opening menu has been structured as a small Japanese meal.
It begins with Okuno’s foie gras chawanmushi with seasonal vegetable sauce.
The upper section of the box includes a selection of smaller dishes such as simmered vegetables, seasonal greens, white-fish fritter and dressed chicken.
The lower section contains the seafood bara-chirashi built around fresh bluefin tuna.
Miso soup and a coffee-flavoured mizu-yokan sweet complete the meal.
Individual dishes can change because the kitchen adjusts the menu according to the condition of ingredients and the season.
At ¥3,800, this is a completely different decision from the ¥25,000 dinner.
We wouldn’t hesitate to consider it as part of a Tokyo National Museum day.
Do You Need a Lunch Reservation?
No.
Lunch walk-ins are accepted.
However, there’s an important catch.
If you walk in without a reservation, you need to enter the Tokyo National Museum normally, which means having a valid museum admission ticket.
If you’ve booked a course in advance and follow the entry instructions provided with your reservation, you don’t need to purchase separate museum admission just to reach the restaurant.
That creates two sensible ways to use lunch.
If you’re already planning to visit the museum, simply work Okuno into the day.
If your main reason for going is the restaurant, consider making a reservation.
And remember how small it is.
There are only eight counter seats and one eight-seat private room.
“Walk-ins accepted” doesn’t mean we’d assume a table will be waiting at exactly 12:30pm on a busy day.
Sushi Kaiseki Okuno Dinner: ¥25,000
Dinner is where Okuno becomes a destination restaurant.
The current grand-opening special course costs:
¥25,000 per person, including tax and service.
This is worth emphasising because articles written before the restaurant opened may show a different price.
Earlier promotional information listed a ¥35,000 sushi-kaiseki course.
The restaurant ultimately launched its opening special dinner at ¥25,000.
That’s the current opening menu we’d use when budgeting.
What Do You Eat at Dinner?
This isn’t simply ten expensive pieces of nigiri.
The opening example gives a much better idea of what Okuno means by sushi kaiseki.
The meal begins with hairy crab and caviar in a chrysanthemum sauce.
There’s abalone steamed for six hours and dressed with its liver.
Sushi includes bluefin tuna toro, alongside seasonal fish prepared according to the chef’s judgement.
The course moves through dishes such as tilefish with matsutake, kawahagi wrapped with its liver and grilled Spanish mackerel pressed sushi.
Then comes something you wouldn’t necessarily expect at a sushi counter:
Chateaubriand prepared in a jibuni-style simmered dish.
Later courses include straw-seared returning bonito, a grilled-eel hand roll, red miso soup with fresh seaweed and a walnut-mochi dessert.
The precise menu can change with the season and the quality of ingredients available that day.
That’s how we’d want a meal like this to work.
If you’re paying for seasonal Japanese cuisine, we’d rather the chef change a fish because something better arrived that morning than rigidly reproduce a menu printed months earlier.
Dinner Also Includes Champagne During the Opening Period
The current opening dinner includes a glass of Champagne.
Groups of four or more receive a bottle.
That’s part of the grand-opening arrangement rather than something we’d assume will remain forever.
Okuno explicitly says the current opening menu will eventually be replaced by its regular menu.
So if you’re reading this later in 2026 or in 2027, check the current offering before booking.
That’s also why we’d be careful about old articles quoting exact dishes indefinitely.
Do You Need a Dinner Reservation?
Yes.
Dinner is completely reservation only.
You can’t simply finish walking through Ueno Park at 6:30pm and decide to see whether Okuno has a spare counter seat.
Reservations are currently taken by telephone.
They can be made up to three months in advance.
If you’re visiting Tokyo for a special occasion and have a specific date in mind, we’d book earlier rather than treating this like an ordinary neighbourhood sushi restaurant.
There are only 16 seats in the entire restaurant when the private room is included.
How Do Foreign Visitors Book?
This is probably the biggest weakness in the experience for international tourists at launch.
The restaurant’s website has English information, but reservations are currently made by telephone rather than through a simple online booking calendar.
The reservation number published by Okuno is:
070-2252-1116
When making the reservation, you’ll need to provide details including your party size, desired time and menu.
The restaurant then explains the correct arrival procedure.
If you’re uncomfortable making a restaurant reservation in Japanese, ask your hotel concierge whether they can assist.
For a ¥25,000 dinner, we’d rather confirm everything properly than hope the language barrier sorts itself out when you arrive.
Can You Visit Okuno Without Paying Museum Admission?
This is more nuanced than a simple yes or no.
If you have a course reservation
You don’t need to buy a separate Tokyo National Museum admission ticket provided you follow the restaurant’s entry instructions.
Those instructions are given when your reservation is accepted.
If you walk in for lunch
You do need normal museum admission to enter and reach Okuno.
This is one of the most useful things to know before visiting.
Don’t turn up at the museum entrance for an unreserved lunch and argue that you’re only going to the restaurant.
The official policy distinguishes between booked course guests and walk-ins.
How Does Dinner Work After the Museum Closes?
This is one of the details that makes Okuno unusual.
The restaurant operates later than the museum’s normal daytime gallery schedule.
Dinner currently runs until 10:00pm.
The interior was specifically designed so guests can continue dining calmly after the museum itself has closed.
Because access is different in the evening, Okuno provides dinner guests with arrival instructions when the reservation is made.
Follow those rather than assuming you’ll use exactly the same entrance as a daytime museum visitor.
What Time Is Lunch?
Current lunch hours are:
11:00am–2:00pm
Food last order is at 1:00pm.
Drinks last order is at 1:30pm.
We wouldn’t arrive at 12:55pm hoping for a leisurely museum lunch.
If you’re combining the restaurant with the Tokyo National Museum, give yourself enough time to actually enjoy both.
What Time Is Dinner?
Current dinner hours are:
5:30pm–10:00pm
Dinner is reservation only.
The restaurant closes on the same days as the Tokyo National Museum.
Always check the museum calendar when planning because closure days can be affected by holidays and museum scheduling.
What Should You Wear?
There isn’t a strict formal dress code.
That doesn’t mean we’d arrive in beach clothes.
Okuno says most guests choose to wear a jacket, and it may refuse entry to guests wearing collarless shirts, shorts or sandals.
The restaurant also asks guests to avoid strong fragrances.
That last point makes particular sense at a sushi counter.
A strong perfume sitting beside someone trying to appreciate delicate fish isn’t ideal.
For dinner, we’d dress smart casual.
You don’t need a suit and tie.
But this is a ¥25,000 dinner inside the Tokyo National Museum. Dress accordingly.
Is Sushi Kaiseki Okuno Good for Tourists?
Yes, with one qualification.
The restaurant itself has made a reasonable effort to accommodate international visitors. Its official information is available in English and the concept doesn’t require you to speak Japanese to enjoy the meal.
The awkward part is the phone-only reservation system.
Lunch is therefore considerably easier for a spontaneous overseas visitor.
Walk into the museum, see the galleries and have the ¥3,800 lunch if seating is available.
Dinner requires more planning.
But that’s not necessarily a bad thing.
With only eight counter seats, Okuno isn’t trying to process hundreds of tourists every night.
Is the ¥3,800 Lunch Worth It?
Based on the current opening menu, this is the easiest part of Okuno to recommend.
¥3,800 isn’t cheap lunch by Tokyo standards.
But you’re getting fresh bluefin tuna bara-chirashi, several smaller seasonal dishes, foie gras chawanmushi, soup and dessert inside the Gallery of Horyuji Treasures.
The setting matters.
If all you want is inexpensive sushi, don’t come here.
Tokyo has countless cheaper options.
If you want a good lunch that becomes part of a Tokyo National Museum visit, ¥3,800 feels much easier to justify.
That’s the distinction.
Is the ¥25,000 Dinner Worth It?
This requires a different standard.
At ¥25,000 per person, a couple is spending ¥50,000 before any additional drinks.
Tokyo has serious competition at that price.
There are exceptional sushi counters throughout the city, and someone purely chasing the highest possible level of nigiri may prefer to spend the money at a dedicated sushi specialist.

Okuno makes more sense when you’re buying the entire evening.
The museum setting.
The architecture.
Eight counter seats.
Seasonal kaiseki.
Sushi.
Dinner continuing after the museum has closed.
That’s a much more compelling reason to choose it.
Who Should Book Dinner?
We’d seriously consider it for an anniversary, birthday, honeymoon or one major food experience during a Japan trip.
It’s also interesting for someone who has visited Japan before and no longer needs every evening to be spent racing between Tokyo’s major sights.
And it could suit travellers who appreciate Japanese architecture and museums as much as food.
You’re essentially extending a cultural day into dinner rather than separating sightseeing and dining into two unrelated activities.
Who Should Skip Dinner?
Skip it if ¥25,000 per person would put pressure on the rest of your trip.
You don’t need to spend this much to eat excellent sushi in Tokyo.
That’s important.
A high price doesn’t automatically make something an essential Japanese experience.
If you’re travelling on a moderate budget, have the ¥3,800 lunch instead and put the remaining ¥21,200 towards several other meals.

Likewise, if your only objective is “eat great sushi”, compare your options before deciding that a museum setting is worth paying for.
Okuno Lunch vs Dinner
This isn’t really a choice between a cheap and expensive version of the same meal.
They’re different experiences.
Lunch is the accessible option: bluefin tuna bara-chirashi, smaller dishes and the chance to combine a good meal with a museum visit.
Dinner is the occasion: a multi-course sushi-kaiseki menu in a tiny restaurant after normal museum hours.
For a first-time visitor who isn’t sure?
Lunch.
For someone celebrating something?
Dinner.
For a serious sushi traveller?
We’d compare Okuno against the specialist counters on your shortlist before deciding.
Is Okuno Better Than a Normal Tokyo Sushi Restaurant?
Not necessarily.
And we wouldn’t write the article as though it is.
The appeal is different.
At a specialist omakase counter, the chef and progression of nigiri can be the entire reason you’re there.
At Okuno, sushi shares the stage with kaiseki dishes, architecture and the museum.
Neither approach is automatically superior.
Think about what memory you’re trying to buy.
If you want to remember eating incredible sushi, choose the restaurant you think serves the sushi you most want to experience.
If you want to remember having sushi kaiseki inside the Tokyo National Museum after closing, Okuno has an obvious advantage.
Can You Combine Okuno With Asakusa?
Yes, and this is how we’d probably use it on a sightseeing trip.
Asakusa and Ueno sit relatively close together in eastern Tokyo.
Spend part of the morning around Senso-ji and the surrounding streets, then move to Ueno for the Tokyo National Museum.
From there, lunch at Okuno fits naturally.
Alternatively, spend the afternoon properly exploring the museum and book dinner afterwards.
That gives you a much more coherent day than bouncing between opposite sides of Tokyo.
Is the Tokyo National Museum Worth Visiting Too?
Yes.
We wouldn’t treat the museum merely as the hallway you walk through to reach lunch.
It’s Japan’s oldest national museum and holds one of the country’s most important collections of Japanese and Asian art and cultural objects.
If you’ve booked lunch, give yourself time around it.
For someone interested in Japanese history, art, Buddhism, samurai armour, ceramics or traditional crafts, the museum can occupy hours rather than minutes.
This is also why Okuno is more interesting than opening the same restaurant in a random luxury hotel.
The location contributes something meaningful.
How We’d Plan the Day
We’d choose one of two approaches.
For lunch, enter the Tokyo National Museum in the morning, spend time in the galleries and eat at Okuno before continuing around Ueno.
For dinner, make the museum the afternoon activity and allow the meal to become the end of the day.
Don’t schedule a 5:30pm Okuno dinner and then plan to race across Tokyo for a 7:30pm attraction.
Kaiseki isn’t something we’d pay ¥25,000 for and then hurry through.

What About Ginza for High-End Dining?
Ginza is still one of the obvious areas to consider if your priority is a special Tokyo meal.
It has a far greater concentration of high-end restaurants and gives you many more choices across sushi, kaiseki and other Japanese cuisines.
👉 Best Restaurants in Ginza 2026: 15 Places Worth Eating
Okuno isn’t trying to compete with Ginza on restaurant density.
Its advantage is that there’s only one Okuno inside the Gallery of Horyuji Treasures.
Again, the setting is what makes the decision interesting.
A Note About the Current Prices
This is important because Okuno has literally just opened.
The ¥3,800 lunch and ¥25,000 dinner are grand-opening menus.
The restaurant has already stated that these will eventually be replaced by its regular menu.
So don’t assume those exact prices will remain forever.
We’d check again before travelling, particularly if your Tokyo trip is several months away.
It’s also why you may see ¥35,000 quoted elsewhere online.
That price appeared in information released before opening.
The actual opening special dinner launched at ¥25,000.
Reservations and Cancellation
Reservations can currently be made three months before your intended visit.
Changes are handled by telephone.
For table-only reservations, Okuno says there isn’t currently a cancellation charge, but asks guests to contact the restaurant by the morning of the previous day.
Course bookings can involve different conditions, so confirm the terms that apply to your actual reservation.
With only a handful of seats, we’d contact them as soon as possible if plans change rather than simply failing to show.

Final Thoughts
Sushi Kaiseki Okuno could easily have been another expensive Tokyo restaurant with a clever address.
The location is what makes it more interesting.
You’re eating inside a Yoshio Taniguchi-designed gallery housing treasures connected to one of Japan’s most important Buddhist temples.
At lunch, that experience is surprisingly accessible.
¥3,800 for the opening lunch is the option we’d recommend to most travellers.
It gives you a reason to slow down during a Tokyo National Museum visit and have a proper Japanese meal without turning lunch into one of the biggest expenses of the trip.
Dinner is another matter.
At ¥25,000 per person, we’d want the evening itself to matter.
A birthday. An anniversary. A honeymoon. A serious interest in Japanese food. Or simply one night of the trip where you’ve deliberately decided not to worry about the budget.
If that’s what you’re looking for, eating sushi kaiseki inside the Gallery of Horyuji Treasures after the museum has closed is difficult to replicate elsewhere.
If it isn’t, don’t force it.
Have lunch.
Then spend the other ¥21,200 eating your way through Tokyo.
