Before You Order
〇 About Import Consumption Tax
At the Shaftoya shopping site, we pay the import consumption tax incurred during customs clearance on your behalf, so you will not be charged any additional fees beyond the total amount paid at checkout.
〇Confirmation of Compatibility
Since all product databases are based on North American vehicles (USDM), please confirm compatibility with Japanese vehicles (JDM) before ordering. (If you are unsure if a listed product fits 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 items are sorted by selecting the year, manufacturer, and vehicle model in the tabs on our top page, this does not guarantee a perfect fit for 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 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.
Essentially, all products are shipped internationally from our warehouse in the United States. Unlike domestic shipping in Japan, 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 check the estimated delivery date. Please note that all products are transported by air freight; they are not shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products handled by our company are designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide structural strength documentation or similar paperwork for these systems. Therefore, all parts are sold for the purpose of "use on circuits, private land, or off-road," and installation and use are at the user's own risk.
○ Regarding Warranty
Please check the contents of your order immediately upon arrival. Since all products are shipped internationally from outside Japan, the packaging or the product itself may sustain shipping damage. Please understand that we only provide returns, refunds, or replacement services for items with 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 will be handled "exclusively through us." Please note that we do not coordinate with other companies or agencies located within Japan regarding warranty issues.
