Before You Order
〇 Regarding Import Duties
At Shaft-ya, we cover the import consumption taxes incurred during importation; therefore, there will be no additional charges beyond the total amount paid at checkout.
〇Compatibility Check
As our product database is based on North American (USDM) vehicles, please confirm whether the parts are compatible with Japanese (JDM) vehicles before ordering. (Please feel free to contact us if you are unsure whether a listed product is compatible with your vehicle. Our support team will be happy to investigate for you.)
We cannot accept returns due to incompatibility if an order is placed without prior confirmation of compatibility.
Please note that even if items are sorted by year, make, and model using the tabs on our top page, this does not guarantee a direct, modification-free fitment for Japanese-market vehicles.
All product descriptions have been translated into Japanese using translation software. Due to potential inaccuracies in phrasing, 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 shipping address on the checkout page. For large items such as body parts, the actual shipping cost may occasionally differ significantly from the automated calculation. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our U.S. warehouse. Unlike domestic Japanese shipping, international delivery takes approximately 7 to 14 days, so please allow ample time when ordering. If you are in a hurry, please contact us in advance to verify delivery times. All products are shipped via air freight; we do not use sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken)
The products we carry are generally designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese Vehicle Inspection (Shaken) System," and we are unable to provide documents such as strength calculation reports 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 inspect the contents immediately upon arrival. Since all products are shipped internationally, there is a possibility of shipping damage to the packaging or the product itself. Please understand that we can only offer returns, refunds, or exchanges for shipping damage, defective products, or incorrect items if notified within 7 days of receipt. Furthermore, for products sold through our company, all warranty-related support must be handled "exclusively through us." Please be aware that we do not facilitate support through other domestic Japanese companies or agencies.
