Time for stay
We offer an 100-minute stay (110 minutes during dinner time) from the time of your arrival with a butler’s greeting until your departure.

Matters related to reservations
Do I have to reserve in advance?
For reserved seats through August 9, 2026
Generally, we ask that you make a reservation in advance when using our estate.
However, if there are vacant tables available on the day of your visit, you are welcome to visit us even without a reservation.
We will provide information on the availability of tables on the day at the entrance of our estate.
For reserved seats on or after August 10, 2026
Generally, we ask that you create an account and make a reservation in advance via our website when visiting us.

Can I get in your cafe if I come directly?
If you wish to visit us and there is a “vacant” indication on the information board at the entrance or on our website, please inform the doorman directly on the day.
Please note that we cannot respond to inquiries regarding the availability of tables on the day by email or phone in advance, so please understand this beforehand.
Unable to Select Your Preferred Date on the “Reservations” Page.

If the desired table is not indicated on the “Reservation” page, it may already be fully booked or the estate may be closed on the day.
Regarding estate closures, we provide information on our website under “Closure and Time Changes”.
For reserved seats on or after August 10, 2026
If a date cannot be selected on the calendar within the “Reservations” page, it means that the date is either a closed day or outside the reservation acceptance period.
Similarly, if a date is marked as “Fully Booked”, reservations cannot be made for that date.
Regarding closure days, we provide information on our website under “Closure and Time Changes”.
How should I get in the waiting list?
We are not currently accepting waitlists or cancellations.
As long as there is room available, cancellations will be treated as a regular reservation request.
Please note that we cannot respond to inquiries regarding the availability of tables on the day by email or phone in advance, so please understand this beforehand.
I do not receive your confirmation mail after temporary reservation.
* For reserved seats through August 9, 2026
From 12:00 a.m. to around 12:30 a.m., there may be delays in email delivery due to server load caused by concentrated processing.
If you do not receive the email even after waiting for a while, there may be an error in the email address you entered.
The provisional reservation process also serves as a confirmation of the customer’s identity for the reservation.
However, we cannot physically address issues such as incorrect email addresses or non-delivery due to various service settings, so we cannot accept corrections or retransmissions.
In this case, we apologize for the inconvenience, but we ask that you go through the reservation process again.
In addition, if there is a “.” (period) in the account name (the string before “@”) during reservation reception and you specify a “docomo.ne.jp” domain email address, it has been confirmed that the email at the time of application may not be delivered.
The cause and solution of this issue have not yet been determined, and in order to ensure a smooth process, the only option is to use a different email address or change the account name.
Received an email after making a temporary reservation, it says “different from the email address used at the time of reservation” during the final reservation process.
* For reserved seats through August 9, 2026
When entering your email address, there is a possibility that you may have made a mistake between upper and lower case letters or accidentally inserted a space.
We apologize for the inconvenience, but please reapply with a new application.
Also, if you try to complete the process after making a temporary reservation during busy times, you may receive this type of error message.
To smoothly complete the process after making a temporary reservation, please avoid doing so immediately after midnight.
Thank you for your cooperation.
Feel uncomfortable entering personal information such as your name.
For reserved seats through August 9, 2026
We ask for the representative’s address and phone number to ensure smooth operation, as it can be very difficult for us in the event of a cancellation just before the promised date or without any prior notice.
In the case of any inadequacy in the information provided, we may not be able to reserve a table for you, so we kindly request your cooperation.
For reserved seats on or after August 10, 2026
When making a reservation through our website, we kindly ask that you create an account in advance.

Please note that even when visiting with same-day availability, we may ask for personal information as necessary to assist you.

How many people can make a reservation?

Please note that we are unable to accommodate changes exceeding the allowable number of guests.
If your party size is determined in advance, we kindly ask that you make a new reservation for a table that suits your preferred number of guests.
I want to change the representative person.
If the primary guest is unable to visit due to unforeseen circumstances, please note the following:
A change of the primary guest is permitted only if the membership card number of an accompanying guest was provided in advance at the time of reservation.
In such cases, no prior notice is required; however, please inform the doorman at the entrance of the change upon arrival.
If the accompanying guest’s membership number was not provided at the time of reservation, we may be unable to accommodate a change of the primary guest on the day of your visit.
In this case, you are required to contact us in advance via the inquiry form.
Please note that in either case, if changing the reservation holder results in the number of guests falling below the minimum party size required for the reservation, a cancellation fee for the reduction in the number of guests will apply.
We regret that we are unable to accept any changes to the primary guest that do not meet the above conditions.
Furthermore, if it is found that multiple membership numbers have been intentionally entered beyond the allowed number of guests, or that a reservation was made with the intent of transfer or reassignment, we may refuse future visits.
