About the course

I would like to change my Silver Key (monthly subscription) plan from the 330 yen plan to the 550 yen plan.

We have revised our membership fees as of June 2, 2025.

Members who were enrolled in the 330 yen course before the revision will not be automatically switched to the 550 yen course.

If you wish to change to the 550 yen course, please proceed via the URL below.

* If you switch from the 330 yen course to the 550 yen course in the middle of the month, it will not be a double payment, and you will be charged 330 yen in the month of the change and 550 yen from the following month.

* "SP Mode Payment" is not available for the 550 yen course. We apologize for the inconvenience, but please change to another payment method such as d Payment.

Please note that while you can continue using the 330 yen plan, future advance ticket sales for live performances and other new services for "silver key" members will only be available to members of the revised 550 yen plan.
