Before You Order
〇 Regarding Import Duties
At Shaftoya Shopping Site, we pay the import duties incurred during importation on your behalf, so there are no additional charges beyond the total amount paid at checkout.
〇 Verification of Compatibility
Our entire product database is based on North American vehicles (USDM). Please verify compatibility with your Japanese vehicle (JDM) before placing your order. (If you are unsure if a listed product is compatible with your vehicle, please feel free to contact us; our support team will be happy to investigate for you.)
If you order without verifying compatibility, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by model year, manufacturer, and vehicle model using the tabs on our homepage, it does not necessarily mean they will fit Japanese-model vehicles without modification.
All products have been translated into Japanese using translation software. There may be confusing expressions, so please contact us before ordering if you have any questions.
○ Regarding Delivery
Shipping costs are paid at checkout. Shipping cost estimates are automatically calculated 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 cost. In such cases, we will contact you individually by email.
All products are generally shipped internationally from our US warehouse. Unlike domestic Japanese delivery, international shipping takes approximately 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 check delivery times. All products are shipped via air freight; they are not shipped via sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Please be aware that all products we handle are designed and manufactured outside of Japan. They are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide structural review documents or similar paperwork for these systems. 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. Because all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product itself. Please understand that we will only provide returns, refunds, or replacement exchanges if you notify us within 7 days of receipt regarding damaged items, defective products, or items that differ from your order. Please note that for products sold through us, warranty support will be handled "exclusively through us." We do not provide support through other companies or distributors based in Japan.
