Kohaku occupies a quiet address in Kagurazaka, Shinjuku City, with a counter built for eight guests. Chef Koizumi Koyuji trained under the Kagurazaka Ishikawa lineage, a background reflected in the restaurant's focus on Edomae sushi technique.
The space offers both counter seating and a private room, and service runs at lunch and dinner on most days. Lunch omakase is available, notably on Saturdays alongside the evening sitting; the restaurant is closed Sundays and Mondays. Dinner service on weekdays and Friday runs from 17:00 to midnight.
Reservations are handled by phone rather than online booking, and the restaurant is described as English friendly, which should ease the process for overseas visitors. Pricing sits at the luxury tier, consistent with a small-format Edomae sushi counter in this part of Tokyo, though exact menu prices are not listed and should be confirmed when booking.
Kohaku's size and format point to an intimate, chef-led omakase experience rather than a high-volume dining room. With only eight seats across counter and private room options, advance reservation by phone is effectively required.
