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 other than the total amount you pay at checkout.
〇Confirmation of Compatibility
Our entire product database is based on North American vehicles (USDM), so please confirm compatibility with Japanese vehicles (JDM) before placing your order. (If you are unsure whether the listed product is compatible with your vehicle, please feel free to contact us. Our support team will look into it for you.)
If you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by selecting the year, manufacturer name, and vehicle model in the tabs on our top page, it does not necessarily mean they are compatible with Japanese-spec vehicles without modification.
All products have been translated into Japanese using translation software. There may be confusing expressions, so please contact us if you have any questions before ordering.
○ Regarding Shipping
Shipping costs are paid at the time of settlement. An estimate for shipping costs will be calculated automatically when you enter your shipping address on the checkout page. For large items such as body parts, the actual shipping cost may occasionally differ significantly from the amount calculated automatically. In such cases, we will contact you individually by email.
Basically, all products are shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please order with enough time to spare. If you are in a hurry, please contact us in advance to confirm the delivery date. All products are transported by air. They are never shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Basically, all products we handle are designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese vehicle inspection system" (Shaken), and we cannot provide documents such as strength calculation sheets for the Japanese inspection system. 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 when the product arrives. Since all products are shipped internationally from outside of Japan, the packaging box or the product itself may sustain shipping damage. Please understand that we will only provide returns, refunds, or replacements for damaged products, 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, we will handle warranty matters "only through us." We do not provide services through other companies or distributors located within Japan.
