Before Ordering
○ Regarding Import Consumption Tax
At Shaft-ya Shopping Site, we pay the import consumption tax incurred at the time of import on your behalf, so there will be no additional charges beyond the total amount paid at checkout.
○ Confirmation of Compatibility
All product databases are based on North American vehicles (USDM). Please confirm whether or not they can be installed on Japanese vehicles (JDM) before ordering. (If you are unsure if the 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 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 using the tabs on our top page, it does not necessarily mean they are compatible with Japanese-market models 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 Delivery
Shipping costs are paid at the time of payment. Shipping cost estimates are calculated automatically once 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 amount and the actual shipping cost. In such cases, we will contact you individually by email.
Basically, all products are shipped internationally from our U.S. warehouse. Unlike domestic delivery within Japan, international delivery 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 check the delivery time. Note that all products are transported by air; they are not shipped by sea.
○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
All products we handle are basically designed and manufactured outside of Japan. Please be aware that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide documents such as strength calculation reports 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 of Japan, there may be damage to the packaging box or product during shipping. Please understand that we will only handle returns, refunds, or exchanges for products with shipping damage, defective products, or items different from your order if you contact us within 7 days of receipt. Please note that for products sold through us, we will handle warranty-related matters "only through us." We do not handle matters through other companies or distributors located within Japan.
