Announcement: New Opt-Out Feature

Starting November 11, 2026, we have added an opt-out feature to My Page.
If you do not want to receive announcement emails, please opt out from My Page.
https://nihongo.hicross.jp/mypage
However, we may still send important messages related to personal information protection or service operation, regardless of your settings.

This is managed separately from the Reminder Email opt-out found on the same page.
