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 Fitment
Our entire product database is based on North American vehicles (USDM), so please check the compatibility 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 check it for you.)
If you place an order without confirming compatibility, we cannot accept returns due to non-compatibility.
Please note that even if items are sorted by selecting the year, make, and model on our homepage tabs, it does not necessarily mean they will fit Japanese model vehicles without modification.
All product descriptions 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 automatically calculated on the checkout page once you enter your shipping address. For large items such as body parts, there are rare instances where there is a significant discrepancy between the automatically calculated shipping cost and the actual shipping cost. In such cases, we will contact you individually by email.
Basically, all products are shipped internationally from our US warehouse. Unlike domestic delivery in Japan, international shipping takes about 7 to 14 days, so please allow plenty of time for your order. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all products are transported by air. They are not shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Basically, all the products we handle are designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide documents such as strength study reports for Japanese inspection purposes. Therefore, all parts are sold for the purpose of "use on circuits, private land, and off-road," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents immediately upon arrival. As all products are shipped internationally from outside of Japan, there may be shipping damage to the packaging or the product itself. Please understand that we will only provide returns, refunds, or exchanges for products with shipping damage, defective products, or incorrect items if you contact us within 7 days of receipt. Furthermore, regarding products sold through our company, warranty support will be provided "only through us." Please note that we do not provide support through other companies or distributors located within Japan.
