Before Ordering
〇Regarding Import Consumption Tax
At the Shaftoya shopping site, we cover the import consumption tax incurred at the time of import, so there are no additional charges beyond the total amount paid at checkout.
〇Compatibility Check
As our entire product database is based on North American (USDM) vehicles, please confirm compatibility with Japanese (JDM) vehicles before ordering. (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 products are sorted by selecting the year, manufacturer, and vehicle model in the tabs on our top page, it does not necessarily guarantee that they 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 before ordering if you have any questions.
○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.
In principle, 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 enough time when ordering. If you are in a hurry, please contact us in advance to confirm delivery times. Please note that all products are transported by air freight. They are not shipped by sea.
○Regarding Compliance with Japanese Vehicle Inspections
The products we handle are basically all designed and manufactured outside of Japan. Please note that they are not compliant with "Japanese vehicle inspection standards," and we cannot provide strength calculation documents for Japanese vehicle inspections. 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. As all products are shipped internationally from outside Japan, there may be shipping damage to the packaging box or product. We will handle returns, refunds, or exchanges only if you contact us within 7 days of receipt for products with shipping damage, defective products, or incorrect items received. Please note that for products sold through our company, all warranty-related support will be handled "exclusively through us." Please understand that we do not provide support through other companies or distributors located within Japan.
