Before Ordering
〇 Regarding Import Taxes
At Shaft-ya Shopping Site, we pay the import consumption tax incurred during importation on your behalf, so there are no additional charges beyond the total amount paid at checkout.
〇 Checking Compatibility
Our entire product database is based on North American vehicles (USDM); please verify whether the product can be installed on a Japanese vehicle (JDM) before ordering. (If you are unsure whether 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 place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, make, and model in the tabs on our top page, this does not necessarily mean they are compatible with Japanese market 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.
〇 Regarding Shipping
Shipping costs are paid at the time of checkout. Shipping quotes are calculated automatically 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 shipping cost. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, 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 confirm delivery times. All products are transported via air freight. They are not shipped via sea freight.
〇 Regarding Japanese Vehicle Inspection (Shaken) Compatibility
The products we handle are basically designed and manufactured outside of Japan. Please note that they do not conform to "Japanese vehicle inspection standards," and we cannot provide strength calculation documents or similar paperwork for these standards. 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.
〇 Regarding Warranty
Please check the contents immediately upon arrival of the product. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product. We will only provide returns, refunds, or replacements for products with shipping damage, defective products, or incorrect items if you contact us within 7 days of receipt. Please note that for products sold through us, warranty-related support will only be provided "through us." Please understand that we cannot provide support through other companies or distributors located in Japan.
