(Addition)

The problem of sending and receiving emails has been resolved.

We apologize for the inconvenience this time.

Yesterday, we migrated our homepage, but in connection with that, there is currently an error in sending and receiving emails.

You may not receive the emails sent to our individuals, including those sent from the inquiry form on this website. We will announce it again when it is restored, so please wait for a while.

Also, if you sent an email after 18:00 yesterday and did not receive a reply from us (there may be no error reply), it is possible that the email has not arrived. In that case, please call us or send it again after recovery.

We apologize for the inconvenience, and thank you for your cooperation.
