Product Description:
Before Ordering
〇 About 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 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), so please check the compatibility for Japanese vehicles (JDM) before ordering. (Please feel free to contact us if you are unsure whether the listed product will fit your vehicle. Our support team will be happy to assist you.)
If you order without verifying compatibility, we cannot accept returns due to fitment issues.
Please note that even if products are sorted by selecting the year, make, and model using the tabs on our top page, it does not necessarily mean they will fit Japanese model vehicles without modification.
All product information is translated into Japanese using translation software. As there may be confusing expressions, please contact us before ordering if you have any questions.
○ Regarding Shipping
Shipping costs are paid at the time of checkout. Shipping estimates are calculated automatically once you enter your delivery address on the checkout page. In rare cases, for large items such as body parts, there may be a significant difference 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 yourself enough time when ordering. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all products are transported via air freight; we do not use 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 "Japanese vehicle inspection standards," and we cannot provide strength evaluation reports or similar documents for Japanese inspection purposes. Therefore, all parts are sold for "circuit, private property, or off-road use only," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents immediately upon arrival. As all products are shipped internationally from outside Japan, there is a possibility of shipping damage to the packaging or the product itself. Please understand that we only provide returns, refunds, or exchanges for shipping-damaged items, defective products, or incorrect items if you contact us within 7 days of receipt. Furthermore, for products sold through us, all warranty-related support will be handled "exclusively through us." Please note that we do not coordinate with other companies or agencies located within Japan.
