Before You Order
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 you will not be charged any additional fees beyond the total amount paid at checkout.
〇 Compatibility Confirmation
As our entire product database is based on North American vehicles (USDM), please confirm compatibility with Japanese domestic vehicles (JDM) before placing your order. (If you are unsure whether a listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to assist you.)
We cannot accept returns due to incompatibility if you place an order without confirming compatibility beforehand.
Please note that even if products are sorted by selecting the year, make, and model from the tabs on our top page, this does not necessarily mean they will fit Japanese models without modification.
All product descriptions 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 payment. 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.
In principle, all products are shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, international delivery takes approximately 7 to 14 days, so please allow sufficient time when placing your order. If you are in a hurry, please contact us in advance to confirm delivery times. All products are shipped via air freight. They are not shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Please be aware that all products we handle are designed and manufactured outside of Japan. They are not compliant with the "Japanese Vehicle Inspection System," and we are unable to provide strength calculation documents or similar paperwork for these regulations. Therefore, all parts are sold for use on "circuits, private property, or off-road," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents of your order immediately upon arrival. As all products are shipped internationally from outside Japan, there is a possibility of shipping damage to the packaging or the product itself. Please understand that for items with shipping damage, defective products, or incorrect items, we will only handle returns, refunds, or exchanges if notified within 7 days of receipt. Furthermore, for products sold through us, all warranty-related support will be provided "exclusively through us." Please note that we do not facilitate support through other companies or distributors located within Japan.
