Before Ordering

〇 Regarding Import Consumption Tax
At Shaftoya, we cover the import consumption tax incurred at the time of import on our end, so there will be no additional charges beyond the total amount paid at checkout.

〇 Checking Compatibility
Our entire product database is based on North American (USDM) vehicles, so please confirm compatibility with Japanese (JDM) vehicles before ordering. (If you are unsure if a listed product fits your vehicle, please feel free to contact us and 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 products are sorted by selecting the year, make, and model on the tabs on our home page, it does not necessarily mean they will fit Japanese model vehicles without modification.
All product information has 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 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 by email.

All products are generally shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow plenty of time for your order. If you are in a hurry, please contact us in advance to confirm delivery times. Please note that all products are transported by air; they are not shipped by sea freight.

○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Basically, all products we handle are designed and manufactured outside of Japan. Please understand that they are not compliant with the "Japanese Vehicle Inspection System" (Shaken), and we cannot provide strength evaluation documents or similar documentation 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 check the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging box or the product itself. Please understand that we will only provide returns, refunds, or replacement products for damaged, defective, or incorrect items if you contact us within 7 days of receipt. Furthermore, for products sold through us, we will handle all warranty-related matters "exclusively through us." Please note that we do not work through other companies or distributors located within Japan for these matters.
