Before You Order
〇 Regarding Import Consumption Tax
At the 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 Confirmation of Fitment
Since all product databases are based on North American vehicles (USDM), please check whether the parts can be installed on Japanese vehicles (JDM) before ordering. (Please feel free to contact us if you are unsure if a listed product fits your vehicle; our support team will be happy to look into it for you.)
If you place an order without confirming fitment, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, manufacturer, and vehicle model in the tabs on our top page, this does not guarantee a direct fit without modification for Japanese market vehicles.
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.
○ Regarding Shipping
Shipping costs are paid at the time of checkout. Shipping estimates are calculated automatically once you enter your delivery 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 cost. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international delivery takes approximately 7 to 14 days, so please allow sufficient time when ordering. If you are in a hurry, please contact us in advance to confirm delivery times. Please note that all products are transported by air freight; they are not shipped by sea.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products we carry are generally designed and manufactured outside of Japan. Please be aware that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength calculation documents for Japanese inspection purposes. Therefore, all parts are sold for the purpose of "use on circuits, private property, or off-road," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, the shipping box and the product itself may sustain shipping damage. Please understand that we only provide returns, refunds, or replacement exchanges for items with shipping damage, defective products, or incorrect items if you contact us within 7 days of receipt. Furthermore, for products sold through us, warranty support will be provided "exclusively through us." Please note that we do not provide support through other companies or distributors located in Japan.
