Before You Order
〇 Regarding Import Consumption Tax
At the Shaftoya 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 you pay at checkout.
〇 Checking Compatibility
Since our entire product database is based on North American vehicles (USDM), please confirm whether the product can be installed on Japanese domestic vehicles (JDM) before placing your order. (If you are unsure whether a listed product is compatible with your vehicle, please feel free to contact us. Our support team will investigate it for you.)
If you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, manufacturer, and vehicle model via the tabs on our top page, it does not necessarily mean they will fit Japanese model vehicles without modification.
All products have been translated into Japanese using translation software. There may be confusing expressions, so please contact us before ordering if you have any questions.
○ Regarding Delivery
Shipping costs are paid at the time of settlement. For shipping estimates, they are calculated automatically once you enter your shipping address on the checkout page. For large items such as body parts, in rare cases, there may be a significant discrepancy between the automatically calculated shipping amount and the actual shipping cost. In such cases, we will contact you individually via email.
Basically, all products are shipped internationally from our U.S. warehouse. Unlike domestic Japanese delivery, 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 to check the lead time in advance. Please note that all products are transported by air; they are not shipped by sea.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products we handle are basically designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide documents such as strength calculation reports for the Japanese vehicle 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 upon arrival. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product. Please understand that we will only provide returns, refunds, or replacement products if you contact us within 7 days of receipt regarding products with shipping damage, defective products, or products different from what you ordered. Please also note that for products sold through us, warranty-related support will be handled "exclusively through us." We do not provide support through other companies or distributors located in Japan.
