Before Ordering

〇 Regarding Import Consumption Tax
At Shaftoya, 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.

Confirmation of Fitment
All product databases are based on North American vehicles (USDM), so please check whether the part can be installed on a Japanese vehicle (JDM) before ordering. (If you are unsure if a listed product fits your vehicle, please feel free to contact us and our support team will look into it for you.)
If you place an order without confirming fitment, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, make, and model using the tabs on our homepage, 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 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 U.S. warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow plenty of time when ordering. If you are in a hurry, please contact us in advance to check the delivery time. Note that all products are transported by air. They will never be shipped by sea.

○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products we handle are 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 evaluation documents or similar paperwork for the Japanese inspection system. Therefore, all parts are sold for "circuit, private property, or off-road use only," 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 packing boxes or the products themselves. Please understand that we will only provide returns, refunds, or replacement exchanges for items with shipping damage, defective products, or items different from what was ordered if you contact us within 7 days of receipt. Furthermore, for products sold through us, warranty support will be handled "exclusively through us." Please note that we do not provide support through other companies or distributors located in Japan.
