Before You Order
〇 Regarding Import Duties and Taxes
At Shaftoya Shopping Site, we pay the import duties and taxes incurred at the time of import on your behalf, so there will be no additional charges beyond the total amount paid at checkout.
〇Confirmation of Compatibility
As our entire product database is based on North American vehicle specifications (USDM), please confirm whether parts can be installed on Japanese market vehicles (JDM) before ordering. (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 confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by selecting the year, manufacturer, and vehicle model in the tabs on our homepage, it does not guarantee that they will fit Japanese market models without modification.
All products are translated into Japanese using translation software. As there may be confusing expressions, please contact us before ordering if you have any questions.
○ Regarding Delivery
Shipping costs are paid at the time of checkout. Shipping estimates are automatically calculated when you enter your shipping address on the checkout page. For large items such as body parts, there are rare cases where the automatically calculated shipping cost differs significantly from the actual 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 order with time to spare. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all items are transported by air freight; they are never shipped by sea.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products we handle are designed and manufactured outside of Japan. Please be aware that they are not compliant with the "Japanese Vehicle Inspection (Shaken) System," and we cannot provide structural strength certification or similar documentation for this purpose. Therefore, all parts are sold for the purpose of "circuit use, private property, and off-road use only," and their installation and use are at your own risk.
○ Regarding Warranty
Please check the contents immediately upon delivery. As 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 for damaged items, defective products, or incorrect items if you notify us within 7 days of receipt. Please also note that for products sold through us, warranty-related support will only be provided "exclusively through us." We do not provide support through other companies or distributors located within Japan.
