Before Placing an Order
〇 Regarding Import Consumption Tax
At the Shaftoya shopping site, we pay the import consumption tax incurred at the time of import on your behalf, so you will not be charged any additional fees beyond the total amount paid at checkout.
〇 Confirmation of Compatibility
All product databases are based on North American vehicles (USDM), so please verify compatibility with Japanese market vehicles (JDM) before placing your order. (If you are unsure whether a listed product fits your vehicle, please feel free to contact us. Our support team will be happy to assist you.)
If an order is placed without verifying compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the model year, manufacturer, and vehicle model in the tabs on our top page, this 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 if you have any questions before ordering.
○ Regarding Shipping
Shipping fees 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 there is a significant discrepancy between the automatically calculated shipping fee and the actual cost. In such cases, we will contact you individually via email.
Basically, all products are shipped internationally from our U.S. 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 inquire about delivery times in advance. Note that all products are transported by air. They are never shipped by sea.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products we handle are fundamentally designed and manufactured outside of Japan. Please understand that they are not compliant with the "Japanese vehicle inspection system," and we are unable to provide strength inspection reports or similar documentation for this purpose. Therefore, all parts are sold for "use on tracks, 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 itself. Please understand that we will only provide returns, refunds, or replacements for damaged, defective, or incorrect items if you notify us within 7 days of receipt. Furthermore, for products sold through our company, all warranty-related support will be handled "exclusively through us." Please note that we do not handle support through other companies or distributors based in Japan.
