Lottery reservation system
of the Tokyo Main Library on Saturdays


(Update: December 2, 2022)

Admission to the Tokyo Main Library has been restricted by a lottery reservation system, but from July 21 (Thu.), the lottery reservation system will be suspended Mondays through Fridays, with admission restricted when the number of simultaneous visitors reaches 1,000. On Saturday, the lottery reservation system will continue, but official registered users may enter without a reservation between 9:30 and noon. However, once the number of simultaneous visitors reaches 1,000, only those with reservations will be allowed to enter. There is no time limit for patrons who enter the library at those times. If you wish to ensure admission after noon on Saturday, please continue to apply in advance using the request form.

If you have already registered as a "simple registered user", please bring your identification document and apply for user registration when you visit the library.

Applications must be submitted no later than 12:00 noon on Friday of the week before your preferred date of visit. Click the link below to access the request form.

We are now accepting admission reservation requests for the following date:
