I'd like to modify my email address.

Authorized mail addresse can be used for changing the password when you lost it, and ACE membership registration and Lysn service can be used without mail address authentication.

If you inevitably want to make changes (typing errors when you wrote down the email address, deleting e-mail addresses, etc.), please send a screenshot image of your mobile fan club membership card and ACE membership code(10digits), copy of your passport to help@lysn.com.

After then we will help you.
If you were an leaving the ACE membership from the fan club community or the Lysn service to modify your mail address, you will lose your ACE membership.

However, if there is an event for which you have applied for participation (starchat event, etc.) there may be disadvantages if you change your email address(account).
