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 are no additional charges beyond the total amount paid at checkout.
〇Confirmation of Compatibility
Since our entire product database is based on North American vehicles (USDM), please confirm whether parts are compatible with Japanese market vehicles (JDM) before placing an order. (Please feel free to contact us if you are unsure if a listed product is compatible with your vehicle; our support team will investigate for you.)
If you order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if a product is sorted by selecting the year, manufacturer, and vehicle model in the tabs on our top page, it does not necessarily guarantee that it will fit Japanese market models 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.
○Regarding Shipping
Shipping costs are paid at the time of payment. Shipping estimates are calculated automatically 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 via 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 allow yourself plenty of time when ordering. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all products are transported by air freight; they are not shipped by sea.
○Regarding Japanese Vehicle Inspection Compatibility
The products we handle are basically designed and manufactured outside of Japan. Please understand that they do not conform to the "Japanese vehicle inspection system" at all, and we cannot provide strength calculation documents for such purposes. Therefore, all parts are sold for the purpose of "use on circuits, private land, or off-road," and installation and use are at your own risk.
○Regarding Warranty
Please check the contents of your order as soon as it arrives. Since all products are shipped internationally from outside Japan, the packaging box and the product itself may sustain shipping damage. Please understand that we only provide returns, refunds, or replacement products if you contact us within 7 days of receipt regarding items with shipping damage, defective products, or incorrect items. Please note that for products sold through us, warranty support will be provided "only through us." We do not provide support through other domestic Japanese companies or agents.
