Please do not order if any of the following policy isn't good for you.
It is not allowed to exclude tax when we ship products to the domestic address. So 8% tax will be added on total amount. (Japanese government is scheduling to raise tax into 10% on October 1st in 2019.)
If there are any customs and duty applies to your order, customers are responsible for all the cost. Each country has their own customs and duty. Therefore, if you have any questions about it, please contact with your country’s customs and duty department. As the packing list states, you are the importer and need to follow the laws of your country.
