Japan Post announced that they will resume EMS (Airmail) service from Japan to the United States effective from June 1. Please check the following for Japan’s Post official announcement. https://www.post.japanpost.jp/int/information/2021/0513_01_en.html

We have only been able to ship back serviced scopes by Sea mail during the EMS suspension period. We apologize for the inconvenience that it took a long time to return the serviced scope. Now that the EMS will resume, we hope to return the scope much earlier than Sea mail. Thank you for your patience. 

Please contact info@deon.co.jp if you wish to send your scope back to us for service, now that EMS will resume soon.
