Well, after refreshing the website and switching to Shopify, we didn't expect this to be the first blog.
Japan has placed shipping restrictions on international packages, including completely ending their SAL shipments as of April 2nd, 2020. (SAL is an inexpensive way to ship packages, though it can take 2-4 weeks to arrive.)
So, due to new COVID-19 restrictions, we can no longer offer the inexpensive SAL service and are switching to airmail and increasing prices to reflect this.
