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
As our entire product database is based on North American vehicles (USDM), please confirm whether the product is compatible with Japanese 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 investigate for you.)
If you place an 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 vehicle model using 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 checkout. Shipping estimates are calculated automatically 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.
Basically, all products are shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow sufficient time when ordering. If you are in a hurry, please contact us in advance to confirm the delivery date. Note that all products are transported by air. They are never shipped by sea.

All products we handle are basically designed and manufactured outside of Japan. Please understand that they are not compliant with "Japanese vehicle inspection standards" at all, and we cannot provide strength evaluation documents or similar documentation for Japanese vehicle inspection purposes. Therefore, all parts are sold for "use on circuits, private property, or off-road," and installation and use are at your own risk.
