02-4．I forgot the email address (ID) I used when I registered as a Travel CUBE member. Is there a way to check which one I used? (Can I change the email address I used at the time of Travel CUBE membership registration?)

If you have forgotten your registered email address, you can check it by clicking on “Travel CUBE Members Who Have Forgotten Their ID” under the “Login” button on the login screen.

If you wish to change your email address, please log in once, open the “Member Information” page via ”My Page” on the “Menu” screen. Then, change it via “Change Email Address (Travel CUBE ID)” on the edit screen.
