Before Ordering
〇 Regarding Import Consumption Tax
At Shaftoya 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 the listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to check for you.)
If you order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, manufacturer, and model using the tabs on our top page, it 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 checkout. Shipping quotes are automatically calculated when you enter your shipping address on the checkout page. For large items such as body parts, there may occasionally be a significant discrepancy between the automatically calculated shipping cost and the actual cost. In such cases, we will contact you individually via email.
In principle, all products are shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please order with enough time. If you are in a hurry, please contact us in advance to check delivery times. Note that all products are transported by air; they are not shipped by sea.
○ Regarding Compliance with Japanese Vehicle Inspections
Basically, all 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 sheets or similar documentation for Japanese inspection purposes. 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 inspect the contents immediately upon arrival. As all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product. We will only accept returns, refunds, or exchanges for defective items or items different from what was ordered 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.
