As a result of the price revision by Japan Post, we must unfortunately raise the price of the shipping cost in full scale, because the rise in transport costs due to reduced airmail (or sea freight) service caused by the COVID-19 pandemic is still expected to continue for some time in future, according to the Japan Post.
Please note that the modified prices will be relatively higher especially for countries in Oceania, Europe, and North America. However, we are happy to suggest you an economical way, like DHL (sometimes it is cheaper comparing with postal airmail service for some countries) or “printed matter” service for a package of a small-size and light weight (withing 2kg) like a few books. In that case, the difference of shipping cost will be refunded accordingly.
This modified price will go into effect on June 1, 2022. Thank you for your understanding and cooperation.
