We use the email address you've provided, but it may have been rejected due to your email settings. First off, try adding "@okcoin.jp" to your list of safe senders and domains*.
*Each email provider has different ways of doing this, so please refer to your provider for those instructions.
Other possible culprits:
(1) Marked as spam
Check your spam settings or junk folder.
*On Gmail, check your "Promotions" tab as well.
(2) Blocked email settings
If your email is set up to reject emails automatically, you may not be able to receive our emails. You can cancel this security setting or add "@okcoin.jp" to your list of safe senders and domains.
Note: even if you have not set up an automatic email rejection, the setting may have been preset by your provider or contract carrier so as to block suspicious e-mails.
(3) The email address you registered was entered incorrectly.
Please contact Customer Support via the inquiry form if the mail is not received after some time.
