Before Ordering
〇 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.
〇 Checking Compatibility
All product databases are based on North American vehicles (USDM). Please confirm compatibility with Japanese domestic vehicles (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 an order is placed without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the model year, manufacturer, and vehicle model via the tabs on our top page, this does not necessarily mean they will fit Japanese model 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.
○ Regarding Shipping
Shipping costs are paid at the time of payment. Shipping estimates are calculated automatically once you enter your delivery address on the checkout page. For large items such as body parts, there are rare instances where there is a significant discrepancy between the automatically calculated shipping cost and the actual cost. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow plenty of time for your order. If you are in a rush, please contact us in advance to confirm the delivery date. Note that all items are transported via air freight. They are not shipped via sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products handled by our company are generally designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese vehicle inspection (Shaken) system," and we cannot provide strength calculation documents for that purpose. 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 Japan, there may be shipping damage to the packaging or the product itself. Please understand that we will only provide returns, refunds, or replacement exchanges for items with shipping damage, defective products, or incorrect items if notified within 7 days of receipt. Please note that for products sold through our company, warranty-related matters will be handled "exclusively through us." We do not provide support through other companies or distributors located in Japan.
