Precedence Use(優先使用)

Certain clubs have a priority to use Japanese-style Room (和室) or Meeting Room #1 (第1会議室) due to room functional reasons.

Application for Precedence Use starts at the beginning of the school year, and after that, we will publicly announce the approved groups, a day of the week, and time. Approved clubs are able to make a reservation 7 opening days ahead of others.

Only groups which require tatami mats can have priority for Japanese-style Room, and only clubs which require electronic organ can have priority for Meeting Room #1.

In order to confirm whether those rooms are available or not, please visit our Office in the building where the room is located.
