reserving the tokyo adidas futsal court

im going in may to tokyo and wanted to set up a friendly with some of the members of japan-guide. last time i was in tokyo i checked out the court but was told i needed reservations. sadly it was towards the last days of my trip. so it was too late to reserve.
This time i plan to reserve the pitch how ever the website doesnt have have a english site. i was wondering if some one can help me reserve the field and have a friendly with us.

any members want to have a match? there is 5 of us that are coming. lets set this up!

i am visiting tokyo in february, is it possible to show up and be involved in a futsal game with strangers? im a bit confused about how to participate, i am going with my girlfriend so booking as a team is not possible?

DOES ANYONE WANT TO SET UP A GAME IN MAY?
I have 5 players so far.


If I were you I would go as soon as you get a chance I think they have a open day where random people can play from what I understood. (I could be wrong)
