Before Ordering
〇 Regarding Import Consumption Tax
At the Shaftoya shopping site, we pay the import consumption tax incurred at the time of import, so there will be no additional charges beyond the total amount paid at checkout.
〇 Compatibility Confirmation
Our entire product database is based on North American specification vehicles (USDM). Please confirm compatibility with Japanese specification 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 be happy to 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, make, and model via the tabs on our top page, this does not guarantee that the product will fit Japanese model vehicles without modification.
All products have been translated into Japanese using translation software. As there may be confusing expressions, please contact us with any questions before placing your order.
○ Regarding Shipping
Shipping costs are paid at the time of checkout. Shipping estimates are calculated automatically when you enter your shipping address on the checkout page. For large items such as body parts, there are rare cases where the automatic shipping calculation differs significantly from the actual shipping cost. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, international shipping takes approximately 7 to 14 days, so please allow sufficient time when placing your order. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all items are shipped via air freight; they are not shipped via sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Please note that all products handled by our company are designed and manufactured outside of Japan. They are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength calculation documents for this purpose. 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 inspect the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, there is a possibility of shipping damage to the packaging or the product itself. Please understand that we will only provide returns, refunds, or replacements for damaged items, defective products, or incorrect orders if you contact us within 7 days of receipt. Please also note that for products sold through us, all warranty-related support will be handled "exclusively through us." We do not provide support through other companies or distributors located within Japan.
