Registration

Are there any email addresses that I cannot use for registration?

You cannot register with email addresses from AOL, tac-net.ne.jp, or i-younet.ne.jp due to their specific configurations.

In addition, the following types of email addresses generally cannot be used because they
do not comply with RFC (Request for Comments), the global internet communication standard:

●Non-RFC compliant email addresses:
1．Contains symbols other than "-", "_", ".", "+", "?", or "/".
2．Uses two or more symbols consecutively.
3．Begins or ends (immediately before the @) with a symbol.
4．Has 64 or more characters before the @ symbol.
5．Exceeds 256 characters in total length.

If your email address contains any of these, please register again with a different address.

●Addresses with the icloud.com domain:
Due to Apple's policy, emails sent from this site may be rejected as "emails that violate Apple's local policy."

We recommend registering with a free email address such as gmail.com or yahoo.co.jp.
