Sasa (日本料理 佐々) is a small counter restaurant in Hiroo dedicated to a philosophy the chef calls “gen-nari,” or “as it is born.” This dashi-led approach aims to preserve the delicate, live-fish perfume and natural umami of top-tier seafood, primarily sourced from the waters around Awaji and Akashi. The experience unfolds at a beautiful single-slab counter, offering a theatrical view of the chef's precise work.
Guests consistently praise the quality of the ingredients. Standout dishes frequently mentioned include a signature sesame tofu (goma-dofu) topped with sea urchin, various preparations of frogfish (okoze) and fugu, and seasonal specialities like bear shabu-shabu. The meal concludes with a multi-variant claypot rice (donabe gohan), which many reviewers cite as a memorable highlight. The cooking is noted for its precise control of heat and its delicate, restrained seasoning that allows the core ingredients to shine.
However, the service can be inconsistent. Several reviewers, particularly first-time and non-Japanese guests, noted that the chef can seem distant and prioritises regulars, offering little explanation of the dishes. A few felt the portion sizes or pacing did not justify the high price point. There is also at least one serious report in reviews of a hygiene issue (a hair found in a dish) and dissatisfaction with how the incident was handled.
Reviewers in 2024 reported the omakase course cost between ¥32,000 and ¥35,200, often with tax and service charged separately. Be aware of pricey optional supplements, such as a black abalone course for around ¥40,000 or a Matsuba crab addition for ¥6,000. With drinks and add-ons, final bills can rise substantially, with one guest reporting a total over ¥70,000. It offers good value for those seeking a purely ingredient-focused kaiseki experience, but may be less satisfying for diners who prioritise warm, sociable hospitality.
