Can you book Ohkusa online?

Not through Tabelog. When we opened the listing on 13 October 2026, it showed a phone number and no online booking calendar. The listing marks the restaurant as accepting reservations, and the number is how you make one.

That is normal for a place like this in Japan. With 8 seats, it can fill from regulars and phone calls alone, so there is little reason to pay a booking platform or keep an online calendar up to date. We explain the pattern in why so many restaurants in Japan only take bookings by phone.

When to call Ohkusa

Ohkusa only takes bookings for the next seven days. The phone line for a date opens at 12:00 noon exactly one week before it, so for a Saturday seat you call the Saturday before at noon. If that day is one of their closing days, the line opens on the next day they are open.

The listing gives these hours: Tuesday to Saturday, 19:00 to 21:30. Japan is nine hours ahead of UTC all year. The call-time checker shows the time there right now.

From outside Japan, dial +81 3-6709-8874. Inside Japan, dial 03-6709-8874.

What the staff will ask

A booking call in Japan follows the same short script almost everywhere. Have these ready before you dial:

• The date and time, plus a second option in case the first is taken.
• The number of people.
• Your name, said slowly. They will write it down in katakana.
• A phone number where they can reach you. A hotel number usually works if you have no Japanese one.
• Allergies or foods you can't eat, said at booking and not at the table.

At Ohkusa in particular:

• The listing gives a maximum booking of two people, so ask before planning a larger group.

The Japanese for each line is in our phrases guide, and the phrase builder writes the script for your date and party size.

Conditions to know before you book

• Reservations are accepted by phone.
• The restaurant lists ¥15,000 to ¥20,000 at dinner. Reviewers on Tabelog report spending ¥20,000 to ¥30,000 per person, so budget for the higher figure.
• Cards accepted (Visa, Mastercard, American Express).
• Closed: Sundays and Mondays.
• Minors are not admitted.
• No photos or video inside the restaurant.
• No service charge or cover charge.

These come from the listing as it stood on 13 October 2026. Prices, hours and closing days change, so open the listing before you plan a day around it. Whatever the terms, keep the booking or cancel early: see how cancellation fees work in Japan.

Let Moshicall make the call

If the language, the time difference or the lack of a Japanese number gets in the way, we can phone Ohkusa for you. The button below opens our booking form with the restaurant's number already filled in. Add your date, time and party size. Our AI calls in Japanese, says at the start that it is an AI calling for a guest from overseas, and emails you what the restaurant said.

It costs ¥1,000 per guest, with a minimum of ¥2,000, and you are charged only if the restaurant confirms the table. If they are full, closed, don't answer or ask us to book another way, you pay nothing.
