Before You Order
〇 About Import Consumption Tax
At Shafutoya shopping site, we pay the import consumption tax incurred at the time of import on your behalf, so there will be no additional charges beyond the total amount paid at checkout.
〇 Checking Compatibility
All of our product databases are based on North American vehicles (USDM), so please check whether they can be installed on Japanese vehicles (JDM) before ordering. (If you are unsure if the listed product is compatible with your vehicle, please feel free to contact us. Our support team will check it for you.)
If you order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by selecting the year, manufacturer, and vehicle model from the tabs on our top page, it does not necessarily mean they are compatible with Japanese-model vehicles without modification.
All products have been translated into Japanese using translation software. As there may be confusing expressions, please contact us before ordering if you have any questions.
〇 Regarding Delivery
Shipping costs are paid at the time of payment. Shipping estimates are automatically calculated when you enter your shipping address on the checkout page. For large items such as body parts, there may occasionally be a significant discrepancy between the automatically calculated shipping cost and the actual shipping cost. In such cases, we will contact you individually by email.
All products are generally shipped internationally from our US warehouse. Unlike domestic Japanese delivery, international shipping takes about 7 to 14 days, so please order with time to spare. If you are in a hurry, please contact us to check the delivery date in advance. Please note that all products are transported by air; they are not shipped by sea.
〇 Regarding Japanese Vehicle Inspection Compatibility
Our products are generally designed and manufactured outside of Japan. Please understand that they do not conform to the "Japanese Vehicle Inspection System," and we cannot provide documents such as strength calculation reports for it. Therefore, all parts are sold for use on "circuits, private property, or off-road," and installation and use are at your own risk.

Please check the contents immediately upon arrival. As all products are shipped internationally from outside Japan, there may be delivery damage to the packing boxes or products. We will only handle returns, refunds, or exchanges for products with delivery damage, defective products, or products different from what was ordered if you contact us within 7 days of receipt. Please note that for products sold through us, all warranty-related matters must be handled "exclusively through us." We do not handle matters through other companies or distributors located within Japan.
