Before Ordering
〇 Regarding Import Taxes
At Shaftoya Shopping Site, we pay the import taxes 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
Our product database is based on North American vehicles (USDM). Please confirm whether the product can be installed on a Japanese vehicle (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 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 choosing the year, manufacturer, and vehicle model in the tabs on our homepage, this does not necessarily mean they will fit Japanese model vehicles without modification.
All products have been translated into Japanese using translation software. There may be confusing expressions, so 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 are rare cases where the automatically calculated shipping cost differs significantly from the actual shipping cost. In such cases, we will contact you individually via email.
Basically, all products are shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow enough time when ordering. If you are in a hurry, please contact us to confirm delivery dates in advance. All products are shipped via air freight. They are never shipped by sea freight.

They are not compliant with "Japanese vehicle inspection standards," and we cannot provide structural calculation documents or similar items for the Japanese inspection system. 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.
