Consumption tax will be levied when businesses sell products in Japan. However, in the case of export, consumption tax is exempted. Consumption tax will be appropriately refunded from the tax office if you declare it appropriately.
In order to obtain the export consumption tax refund, an invoice is required to prove that the cargo was exported.
The invoice can be created by the customer himself at the customs office, or by asking a carrier who has a customs official. Customs officers generally belong to international transportation companies.

In order to receive a consumption tax refund, you need to save a certificate such as a receipt. In our office, we accept deeds not only for bookkeeping but also for certificate arrangement.
