Important Note: Please see below.

Currently, the new member registration system is closed. As all new applications are manually reviewed and approved, this system is only open when staff are available to process those applications.

TAG does not operate a 24HR support system and therefore, this system is available mostly during the normal Japan business hours, Monday-Friday. Weekends and late nights are subject to staff availability. 

Thank you for your understanding.
