Best Japanese Restaurants in Bangkok 2026
Published · Updated
"You're in Bangkok for the Japanese?" The expat at the next stool at Sushi Masato laughed. "Yeah, but on the right Wednesday this counter is better value than Sushi Yoshitake in Roppongi." It is a hard argument to dismiss after the third piece of chū-toro nikiri at the THB 9,500 dinner omakase. Bangkok's Japanese scene runs deeper than most travellers credit it for, partly because thirty thousand expatriate Japanese support it, partly because the Toyosu fish flights land here within twenty-four hours of leaving Tokyo. The eight rooms below are the ones still doing the work right.
Eight Japanese Rooms Worth the Booking in Bangkok
Masato Shimizu opened the Sukhumvit 31 counter in 2017 after twelve years running 15 East in New York, where he held three stars from the New York Times. Fourteen hinoki-wood counter seats, one chef behind the counter, no music. The fish lands twice weekly from Toyosu and the shari is finished with a Tokyo-aged red vinegar Shimizu blends himself. The akami-zuke (marinated lean tuna) and the kohada gizzard shad with a 24-hour kombu cure are the pieces he is known for. The omakase runs eighteen to twenty pieces over ninety minutes.
One lunch seating and two dinner seatings (6:00 and 8:30). Reservations open sixty days out on the restaurant's Line account; prime weekend slots clear within ten minutes.
Ginza Sushi Ichi is the only overseas branch of the Ginza original, which has held a Michelin star in Tokyo since 2010. The Mandarin Oriental Bangkok branch opened in 2014 and the parent rotates senior chefs from Tokyo on six-month placements. The eight-seat counter is the same hinoki wood as the parent. The fish flies in three times a week from Toyosu; the Hokkaido uni is served on the day it lands. The akami nigiri marinated in Kakuida red vinegar shari is the technical benchmark.
This is the room you book when you want the Ginza template at a fraction of the Tokyo price. The dinner omakase at THB 9,800 is roughly half what the parent charges in Tokyo for a comparable course.
Tetsuya Mihara was raised by a fourth-generation tofu maker in Kyoto and opened the Sukhumvit 39 room in 2020 with a single idea: a kaiseki menu built around tofu the kitchen makes that morning from imported Niigata soybeans. The Michelin Guide gave it a star within three years, and the room has held it since. The seven-course kaiseki at THB 7,500 includes a yuba course pulled directly from the soy-milk pot in front of you, an agedashi with dashi the kitchen reduces over four hours, and a rice course in the kamado at the end.
Twenty seats, two seatings per night (5:30 and 8:00). The kitchen rebuilds the menu monthly and posts the new course list on Instagram on the first of each month.
The Bangkok Nobu opened in the Park Hyatt at the end of 2023 and is the most reliable Nobu-template room in the city. The black cod miso at THB 1,650 is the dish anyone visiting orders once, and the yellowtail sashimi with jalapeño at THB 980 is the supporting cast. The room itself is the Rockwell Group's standard Nobu template translated for the Park Hyatt with open kitchen, indigo accent wall, and banquette seating along the perimeter. It works.
This is a corporate dinner room, not a sushi pilgrimage. The Friday and Saturday seatings at 7:30 are the ones that book out two weeks ahead; weeknights take a few days.
The Sühring twins, who hold two Michelin stars at their original German restaurant nearby, opened the Kappo counter on the same Yen Akat compound in 2024 with Tokyo-trained chef Hayato Hatakeyama on the line. Ten seats, one shokunin behind the counter, an eight-course kappo menu that changes weekly. The signature is the donabe-rice course at the end, which Hatakeyama finishes in front of you and serves three ways. The room is the cleanest kappo execution in the city outside of the established sushi-ya.
One lunch and one dinner seating Tuesday to Saturday. Reservations on SevenRooms thirty days out.
Sushi Cyu is the Bangkok branch of the Sapporo izakaya chain and has split its concept into two: an omakase counter at the back and a charcoal-grill izakaya at the front. The counter omakase at THB 4,800 is the best mid-tier sushi value in central Bangkok and the chef sources from the same Toyosu twice-weekly flights as the higher-priced rooms. Twelve to fifteen pieces over seventy-five minutes. The kinki rockfish with sea-salt-grilled tail is the dish to order off the supplementary list.
The grill side runs walk-ins until eleven; the omakase counter requires booking. Lunch is the value play at THB 2,800.
Tetsuya Yu trained at a tonkatsu specialist in Shibuya for eleven years before opening the first Bangkok branch in 2019. The breading mix and the panko grade are imported from his Tokyo supplier; the Kurobuta pork is local. The rosu (fatty loin) at THB 580 and the hire (fillet) at THB 680 are the two orders. The cabbage refill is unlimited; the sesame seeds for the tonkatsu sauce are toasted and ground tableside in a stone mortar. The miso soup with kombu and bonito dashi is made in-house.
This is a counter-only operation; arrive before 12:30 or after 2 for lunch, before 6:30 or after 8:30 for dinner.
Zuma's Bangkok branch sits on the basement floor of the St Regis and runs the same izakaya-robata-sushi-counter template that the London original wrote in 2002. The miso-marinated black cod at THB 2,400, the spicy beef tenderloin with red chilli at THB 1,800, and the wagyu beef rib-eye from the robata at THB 4,800 are the consistent orders. The room is loud and theatrical, the cocktail program is taken seriously, and the bar takes walk-ins.
This is not an authentic Japanese meal. It is the best executive of the Zuma template in Southeast Asia and is the right room for a fifteen-person corporate dinner where half the table does not eat raw fish.
Where Not to Spend Your Japanese Dinner in Bangkok
The Tokyo-import chain sushi counters in the basement of CentralWorld and Siam Paragon trade on chain-name recognition but run frozen fish on conveyor belts. Most hotel "Japanese restaurants" outside the Mandarin Oriental, Park Hyatt, and St Regis are catch-all rooms running teppanyaki, sushi, and ramen poorly out of the same kitchen. The "Japanese fusion" rooms in Thonglor get write-ups they do not earn; the kitchen is Thai with Japanese garnish, and the fusion does neither side well.
If you want what these rooms sell, go to Yu Tonkatsu for honest fried pork, Sushi Cyu for honest mid-tier sushi, or Zuma for the executed-fusion version. None of the above are worth a booking ahead of those.
How to Pick the Right Japanese Room for Your Evening
: Sushi Masato first, Ginza Sushi Ichi second, Sushi Cyu third in descending budget order. All three serve Toyosu fish; the spread is in service style and price.
: Mihara Tofuten is the only proper kaiseki-style room in Bangkok with a Michelin star. Sühring Kappo is the kappo-format alternative if you want counter-side cooking rather than seated kaiseki.
: Zuma if the group is 12+, Nobu Bangkok if the group is 6 to 10, Sushi Cyu if the group is 4 and serious about food. Skip Sushi Masato for groups larger than two; the counter format does not work for business conversation.
: Yu Tonkatsu for the fried-pork meal, Sushi Cyu's lunch omakase at THB 2,800 for the mid-tier sushi, Mihara Tofuten's lunch kaiseki at THB 4,500 for a serious midday meal.
Booking Strategy for Bangkok Japanese in 2026
Sushi Masato runs Line-only reservations 60 days out at 10:00 ICT; the prime weekend counter seats clear in ten minutes. Ginza Sushi Ichi books through the Mandarin Oriental concierge or by phone at +66 2 659 9000, with 45-day lead time for Friday-Saturday counter seats. Mihara Tofuten posts the monthly menu on Instagram on the 1st of each month and opens the booking window for that month on the 3rd via Line. Sühring Kappo runs SevenRooms at 30 days. Nobu Bangkok and Zuma run OpenTable at 30 days. Sushi Cyu and Yu Tonkatsu take same-week reservations through Line and walk-ins outside peak.
The single biggest tactical move: for any of the omakase counter seats, ask explicitly for the counter (kaunta seki) not a table. Most online forms default to table seating.
