Japan Post has suspended all forms of Airmail to a number of countries, including the United States. Please see the updated list here:
Right now, the only option for shipping to these countries is Surface Mail, which takes 2-3 months on average. For now, I will be relying on surface mail to ship out your orders. The waiting period will be long, but I figured it would be better than waiting an unspecified amount of time for the airmail services to be restored. Tracking and insurance will still be provided for your packages. I apologize again for the slow progress. This pandemic has really thrown a wrench into the works. If you have any questions, please contact me at email@example.com.
