Japanese Restaurant Bangkok Guide: 18 Places Ranked by Style, From Thonglor Omakase to Soi 33 Izakayas

Japanese food in Bangkok: Phrom Phong’s Soi 33 and 39, Thonglor and Thaniya

Three neighbourhoods do most of the work. Phrom Phong has the densest cluster on this list. Ramen Tei is on Soi 33/1, Yukari on Soi 33, Don Don’s monjayaki at the end of a lane off Soi 39, and EmQuartier’s Helix floors carry the Tokyo brands MAiSEN and Unagi Yondaime Kikukawa; see EmQuartier restaurants. Thonglor is the dining-out hub, with omakase counters, kaiseki, izakayas and an udon shop all within a few hundred metres of the BTS; see Thonglor restaurants. Soi Thaniya in Silom is the office district’s Japanese street, quiet by day and full of izakaya, ramen and sushi counters after dark. For more on Phrom Phong, see Phrom Phong restaurants.

Best Japanese restaurants in Bangkok, ranked

Ryuzu is first because its courses and prices are all published and Google rates it 4.9 from more than 500 reviews. A 14-course lunch costs 3,500++ baht, and Wanderlog reviewers single out the rice seasoned with aged red vinegar. Kitaohji is second for kaiseki in a ryokan-style setting with a Zen garden and kimono-clad staff, though some reviewers find the sauces salty-sweet and come for the room. Teppen Sathorn has the most Google reviews on the list, 4,135, and is loud by design, a show kitchen built for birthdays. Hokkaido Genshiyaki is the Thaniya pick for slow-grilled fish. Mensho is the ramen pick, and Tamaruya and Oniku to Gohan are the two grills. After that the list runs by style: eel and tonkatsu specialists, izakayas, and the everyday noodle shops.

Omakase and sushi in Bangkok, by price tier

At the top, Ryuzu’s 18-course menu at 8,900 baht carries four pieces of uni, Bafun and Taka, and a Nagasaki beef with uni course that THE STANDARD calls the signature. Its 16-course Signature Experience sits in the middle at 5,900++ on the restaurant’s courses page (THE STANDARD had it at 5,800), and the 14-course lunch at 3,500++ is the entry point; all three are before service charge and VAT. The site’s page text lists sessions at 12:00, 17:30 and 21:30, its booking data gives a 19:30 dinner round, and the 2025 review gives 12:30, 17:30 and 19:30, so confirm your seating when you book on LINE. Kitaohji’s Hanare counter does what it calls meat kappou, a wagyu-led omakase, beside its seasonal kaiseki. For sushi in a livelier room, Teppen Sathorn serves omakase sushi and thick-cut sashimi, and Nagiya on Thonglor Soi 9 puts an anago roll at 408 baht next to its grill.

Best ramen and udon in Bangkok

Mensho Tokyo is the bowl to cross town for. It comes from Tomoharu Shono’s Tokyo group, makes its noodles by hand and uses a milky chicken broth. City Nomads and Time Out both list a break between lunch and dinner, while Google shows it open straight through, so call 091 887 9492 before a mid-afternoon visit. The wagyu miso ramen at 390++ and a vegan tantanmen made from seaweed, mushroom and soy cream are both on City Nomads’ list. Ramen Tei on Soi 33/1 is the other kind of ramen shop, one of five branches of an old chain, with a counter where misokara ramen costs 250 baht and Time Out calls the fried chicken with house sauce a must-order. Tsuru Udon by Thonglor Soi 2 kneads and cuts its udon daily and draws its dashi from bonito and kombu. Order the kamatama niku or the mentai cream, and use the QR code at the table. Thonglor Yokocho’s Hokkaido soup curry is the wildcard, with a heat scale from 1 to 100.

Izakayas and yakiniku in Thonglor, Ekkamai and Asok

Thonglor’s izakayas are for groups. Nagiya has 95 seats, a terrace and skewers at about 30 baht, and Thonglor Yokocho recreates a Showa drinking alley with 110 seats and a private room, taking groups of six to thirty; it has only three parking spaces out front, on odd-numbered days. In Ekkamai, Fatboy cooks Japanese small plates with Western twists and opens from noon Friday to Sunday, and Teppen Ekkamai is the original of the straw-grill brand, with rice bowls from 360 to 990 baht and no parking of its own. Around Asok, the grills take over. Tamaruya Honten sources beef from Hida and Hokkaido and stamps parking at the Hilton or Pullman. Oniku to Gohan grills over a small shichirin at the table, wraps your leftover rice as onigiri to take home, and stays open until 02:00. Kenshin Izakaya on Asok Montri Soi 1 is the after-work room where nothing on the bill is added at the end. For more in the area, see Ekkamai restaurants.

Japanese restaurants in Silom and Thaniya

Silom’s Japanese restaurants cluster on Soi Thaniya and around Thaniya Plaza, a short walk from BTS Sala Daeng. Hokkaido Genshiyaki at the Silom end of the soi is the one ranked here, for its central charcoal hearth, its grilled hokke and Atka mackerel, and a private room that takes groups; book on TableCheck, or call for parties over 13. Across in Sathorn, eight minutes from BTS Chong Nonsi, Teppen Sathorn rates 4.8 from 4,135 Google reviews and, according to BKKStay, gives two hours’ free parking. For the rest of the street’s ramen, sushi and yakiniku counters, see Silom restaurants.

Affordable Japanese food in Bangkok and mall favourites

The cheapest good Japanese meals are noodles and set lunches. Ramen Tei’s bowls are 200 to 250 baht, Tsuru Udon’s start at 210, and Tamaruya’s 369++ beef set lunch is a fraction of its dinner prices. Kenshin’s net-priced menu keeps a table full of izakaya snacks to about 500 baht a head. In the malls, MAiSEN’s tonkatsu sets come with free refills of rice, miso soup and cabbage; sources disagree on whether it is on floor 7 or 8 of the Helix, so read the directory. Unagi Yondaime Kikukawa, on floor 6 of the Helix Sky Dining, charges about 1,290 baht for a whole-eel hitsumabushi, priced at its One Bangkok branch. Book Ryuzu, Kitaohji, both Teppen branches and Hokkaido Genshiyaki ahead, and call before a mid-afternoon or late visit, because several of these restaurants publish hours that differ between sources.
