Before Placing an Order
〇Regarding Import Consumption Tax
At the 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Checking Compatibility
Since our entire product database is based on North American vehicles (USDM), please confirm whether parts can be installed on Japanese domestic vehicles (JDM) before ordering. (If you are unsure if a listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to check for you.)
If you 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, it 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 settlement. 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 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 shipping in Japan, international shipping takes about 7 to 14 days, so please allow yourself plenty of time when ordering. If you are in a hurry, please contact us in advance to confirm the delivery date. Please note that all products are transported by air. They are never shipped by sea freight.
○Regarding Compliance with Japanese Vehicle Inspection (Shaken)
Basically, all products handled by us 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 calculation sheets for the Japanese inspection system. Therefore, all parts are sold for the purpose of "use on circuits, private land, or off-road," so please install and use them at your own risk.
○Regarding Warranty
Please check the contents immediately upon arrival. Since all products are shipped internationally from outside of Japan, there may be shipping damage to the packaging or the product. We will only handle returns, refunds, or replacements if you contact us within 7 days of receipt regarding products with shipping damage, defective products, or items different from your order. Please note that for products sold through us, warranty support will be handled "exclusively through us." Please understand that we do not handle matters through other companies or distributors located within Japan.
