Sushi Masato

The Verdict

If you have been to Sushi Masato once, the question on a return visit is not whether the quality holds — it does — but whether the experience has deepened. Chef Masato Shimizu has built one of the most credentialed sushi counters in Southeast Asia from a low-key address on Soi Sawatdi in Watthana, and the menu's seasonal architecture, anchored by daily fish shipments from Tokyo's Toyosu Market, means the plates genuinely change across visits. Book it for a special occasion at the ฿฿฿฿ price point; at that level it competes with anything you would find at Harutaka in Tokyo or Sushi Shikon in Hong Kong, and it costs less than both.

The Portrait

Suhrawardi's Soi Sawatdi sits firmly inside Sukhumvit's expat-professional corridor, but Sushi Masato operates as though it has nothing to prove to the neighbourhood around it. The room is quiet and focused. What you see first when you sit down is the counter , pale wood, clean lines, a working surface that communicates intent before a single piece of fish appears. There are no distractions. This is the visual logic of serious omakase: everything that matters will happen directly in front of you.

The seasonal framework is the core of the offer. Spring brings shellfish abundance; winter shifts toward richer, fattier fish. Those raw materials arrive from Toyosu daily, which is not a marketing claim so much as an operational commitment that shapes what arrives on the plate. For a food enthusiast tracking Japanese seasonal produce cycles, that calendar rhythm is the main reason to return across different months rather than treating a single visit as definitive. A second visit in a different season is, practically speaking, a different restaurant.

Chef Masato Shimizu's background spans Japan and New York , two reference points that matter for understanding his technical register. New York's high-end omakase circuit during the period when Shimizu trained there was running some of the most exacting Japanese counter work outside Japan. That experience, combined with years in Japan, puts his technique in a credible peer group. You can request to be served directly by Chef Masato when booking, which is worth doing on a first visit or any occasion where the personal experience matters to you.

The credentialing record supports the price. Sushi Masato has held a Michelin Plate in both 2024 and 2025. It has appeared on La Liste's Leading Restaurants list in consecutive years , 87 points in 2025, 85 points in 2026 , and has ranked on Opinionated About Dining's Asia list three years running, reaching as high as #72 in 2024. A Google rating of 4.8 across 683 reviews adds a volume-weighted signal that aligns with the formal recognition. This is not a restaurant that has been awarded once and coasted; the consistency across independent systems over multiple years is the more significant data point.

Within Bangkok's sushi category, Sushi Masato sits at the leading of the credentialed tier. Peer counters worth knowing include Ginza Sushi Ichi, Sushi Ichizu, In the Mood for Love, Nikaku, and Fillets. None of them carry the same combination of La Liste, Michelin, and OAD recognition simultaneously. If sushi is the priority and credentials are part of the decision, Masato is the answer in this city.

The location in Watthana places it within easy reach of the Sukhumvit hotel corridor, which means it works logistically for visitors staying in that part of the city.
