Before Ordering
〇 Regarding Import Taxes
At Shaftoya Shopping Site, we pay for import taxes incurred at the time of import on your behalf, so there are no additional costs beyond the total amount paid at checkout.
〇 Confirmation of Fitment
All product databases are based on North American vehicles (USDM), so please check whether the parts can be installed on Japanese domestic vehicles (JDM) before ordering. (If you are unsure whether the listed product fits your vehicle, please feel free to contact us. Our support team will check for you.)
If you order without confirming fitment, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, manufacturer, and vehicle model using 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. 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 via email.
Basically, all products are shipped internationally from our US warehouse. Unlike domestic shipping within Japan, 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 in advance to confirm delivery times. All products are transported via air freight. They are not shipped via sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compliance
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 strength calculation documents for the Japanese 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. We will only accept returns, refunds, or exchanges for defective items or incorrect orders if notified within 7 days of receipt. Please note that for products sold through us, warranty-related support is provided "exclusively through us." We do not provide support through other companies or distributors located within Japan.
