Before Ordering
〇 About Import Consumption Tax
At Shaftoya Shopping Site, we cover the import consumption tax incurred during importation, so you will not be charged any additional fees beyond the total amount paid at checkout.
〇 Confirmation of Fitment
Since all product databases are based on North American specification vehicles (USDM), please confirm whether or not they can be installed on Japanese specification vehicles (JDM) before placing your order. (If you are unsure if a listed product is compatible with your vehicle, please feel free to contact us. Our support team will check for you.)
If you order without confirming fitment, 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, this 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 payment. 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.
All products are generally shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please order with enough time to spare. 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 never shipped by sea.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Please be aware that all products we handle are basically designed and manufactured outside of Japan. They are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength calculation documents or similar paperwork 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.
○ Regarding Warranty
Please check the contents immediately upon arrival. As all products are shipped internationally from outside Japan, there may be damage to packaging boxes or products during transit. Please understand that we will only provide returns, refunds, or replacements for items with shipping damage, defective products, or incorrect items if you contact us within 7 days of receipt. Please also note that for products sold through us, warranty support will be handled "exclusively through us." We do not provide support through other companies or distributors located in Japan.
