Japan does not really have public drop in courts or games. Most pickleball games happen indoors at community center and school gymnasiums (multi-use gyms) or on private tennis/pickleball courts and these all require reservations for court time, or reservations to join the events. Many of the public facilities do not allow groups to advertise to the public, which makes it difficult for new players or visitors to drop in on sessions.
So, how can one play pickleball in Tokyo then as a tourist, recent transplant, or a beginner?
The courts require reservations but there are 10 courts and it's generally available last minute. Therefore you can book the courts just-in-time once you've already gathered the players.
The courts require reservations but there are only 2 courts so you will need to book in advance. They also hold open play sessions but the level may be low to complete beginner.
Two courts are available. Conditions may be windy.
One full court is available and one \"fun\" court (half-sized). The full court has narrow space on the sides.
Two courts are available. More expensive than other courts and the conditions can be windy.
As mentioned above, public games are not really a thing in Japan. However, you can find some public games on the home page of this website. They will tend to be full with a waitlist so just join the waitlist and cross your fingers. 5-6 spots tend to open up the day of the event as people cancel last minute.
Some events are restricted by level. If you are restricted, just type in your DUPR rating as a comment with your RSVP.
Please do not show up to any events without permission and only if you are in the confirmed going list. Indoor events always require a set of clean indoor only court shoes. They are really serious about this stuff in Japan.
