Tabelog ratingAt Sushi Oku (鮨 奥), a nine-seat counter in Asakusa, chef Oku—formerly of the famed Sushi Hashiguchi—presents a tightly focused Edomae-style omakase. The experience is defined by the rhythm of savoury small plates (tsumami) alternating with precisely formed nigiri, all built around a perfectly textured, body-temperature shari (sushi rice) seasoned with red vinegar.
Guests consistently praise the quality of the ingredients and the chef's exacting technique. Standout nigiri frequently mentioned include kohada (gizzard shad), toro (fatty tuna), uni (sea urchin), and anago (sea eel). Tsumami like a delicate chawanmushi with flower pepper and steamed abalone also receive high marks. Many diners note the meal's generous length, often over 18 pieces, culminating in the chef's signature kanpyō maki (dried gourd roll). The chef's friendly, unpretentious service is another highlight.
The primary drawback is accessibility. Reviewers report that securing a reservation involves a wait of 12 to 16 months, or even longer. More importantly for international visitors, several non-Japanese guests have reported that the restaurant enforces a policy requiring a Japanese speaker to make the reservation and be part of the dining party.
Reviewers in 2024 paid between ¥22,000 and ¥26,000 for the omakase course. With drinks, final bills were often in the ¥28,000 to ¥35,000 range. Despite the high price, diners almost universally consider it fair value for the quality and quantity, provided you can secure a seat.
