You can create a new Zaiko account by following the steps below.
If you already have a Zaiko account, do not create a new one. On the login page, your “Last used to log in” method is suggested automatically, check that first.
Go to the Zaiko login page ( https://zaiko.io/login ).
Click “Sign Up” in the top right corner.
Enter the required information (name, email address, date of birth, password, etc.).
Check the boxes to agree to the Terms of Service and Privacy Policy, then click “Continue”.
After registration is complete, a confirmation email will be sent to the email address you entered. Follow the instructions in the email to finish the process, and your Zaiko account will be ready to use right away.
Important
If you want to create an AKB48 Group ID, you must register through the AKB48 Ticket Center ( https://akb48.zaiko.io/login ), not through Zaiko.
→ Please note that a Zaiko account and an AKB48 Group ID are separate.Registration is free.
Please register yourself with accurate information (registering with false information is prohibited under the Terms of Service). However, a parent or guardian may register on behalf of a minor.
Note: Registering with a social account
You can also create a new Zaiko account using a social account such as Google, Apple, LINE, or X (Twitter).
In that case, your Zaiko account will be created using the email address registered with that social account.
If you select “Hide My Email” with Apple, a dedicated address different from your usual email address (an address with the @privaterelay.appleid.com domain) will be issued automatically.
In this case, make sure to select “Sign in with Apple” every time you log in going forward.
→ For details, refer to Apple's official support.

Selecting “Sign in with Apple” completes your login or registration for your Zaiko account. If you continue to have trouble with your private relay address, check the Apple official support page above or contact Zaiko support.
