When does U.KAI open its reservation book?

Book on OMAKASE (open dates are posted on the store page) or Tabelog. Five counter seats, dinner only, closed Sundays and holidays. All times are Japan Standard Time (UTC+9).

How do I book U.KAI from abroad?

U.KAI takes reservations online through OMAKASE, which you can use from abroad with your own account and a credit card. If you would rather not, our Tokyo desk can request it for you: ¥12,000 per seat, charged only if the table is secured. A free release-date alert emails you the day before, on the morning of release day (08:00 JST) and about 30 minutes before when the opening time is known; houses that open a little every day come in a weekly summary.

What time zone is the release time?

All times are Japan Standard Time (UTC+9). Release days are computed from the house's published rule and re-checked monthly.
