The Official Shop has specific login requirements. Please check the following points:
1. Password requirements
Passwords must be at least 8 characters and less than 20 characters.
Special symbols cannot be used (e.g., !, ?, #).
2. Login method
You cannot log in with your email address.
Please log in using your AKB48 Group ID and password combination.
3. If you forgot your password
If you have forgotten your password, please reset it here:

Note: You must log out before requesting a password reset.
4. ZAIKO account vs. AKB48 Group ID
“User ID / AKB48 Group ID” displayed → AKB48 Group ID account
“User ID” only → Regular ZAIKO account
A regular ZAIKO account cannot be used for the Official Shop. You need to convert it into an AKB48 Group ID.
