Before Ordering
○ Regarding Import Taxes
At Shaft-ya, we cover the import consumption tax incurred during importation, so there will be no additional charges beyond the total amount paid at checkout.
○ Verification of Compatibility
All product database items are based on North American vehicles (USDM). Please verify compatibility with Japanese vehicles (JDM) before ordering. (Please feel free to contact us if you are unsure if the listed product is compatible with your vehicle; our support team will be happy to investigate for you.)
If an order is placed without verifying compatibility, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by year, make, and model using the tabs on our homepage, it does not necessarily guarantee fitment on Japanese models without modification.
All products have been translated into Japanese using translation software. Please contact us before ordering if you have any questions regarding confusing expressions.
○ Regarding Shipping
Shipping costs are paid at the time of checkout. Shipping quotes are automatically calculated 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 shipping takes approximately 7 to 14 days, so please allow ample time for delivery. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all products are transported by air. They will not be shipped by sea.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
The products we handle are designed and manufactured outside of Japan. Please note that they are not compliant with "Japanese vehicle inspection standards," and we cannot provide strength calculation documents or similar paperwork for the Japanese inspection system. Therefore, all parts are sold for "circuit, private property, or off-road use" only; installation and use are at your own risk.
○ Regarding Warranty
Please inspect the contents immediately upon arrival. As all products are shipped internationally from outside of Japan, packaging and products may occasionally suffer shipping damage. We will only provide returns, refunds, or replacement exchanges for items with shipping damage, defective products, or incorrect items if you contact us within 7 days of receipt. Please understand that for products sold through us, warranty support will be handled "exclusively through us." We do not provide support through other companies or distributors located within Japan.
