Japan requires all importers to pay Consumer and Duty Tax.
Japan Consumer Tax (JCT) is 10%.
When importing products to sell from your Japan online account or website, Foreign Online Sellers must make the declared value on their shipping/commercial invoice the same as their online selling price. A copy of your Online Seller Account Report showing the sales price for each item is required to be submitted with your shipping documents.
