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 are no additional charges beyond the total amount paid at checkout.
〇Confirmation of Compatibility
Since our entire product database is based on North American vehicles (USDM), please confirm the compatibility with Japanese vehicles (JDM) before placing your order. (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 incompatibility.
Please note that even if products are sorted by selecting the year, manufacturer, and vehicle model in the tabs on our homepage, this 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. An estimate for shipping costs will be automatically calculated when you enter your shipping address on the checkout page. For large items such as body parts, there may occasionally be a significant difference between the automatically calculated shipping cost and the actual shipping cost. In such cases, we will contact you individually via 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 order with enough time to spare. If you are in a hurry, please contact us in advance to confirm delivery times. Furthermore, all products are transported by air freight; they are never shipped by sea freight.
○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
All products we handle are basically designed and manufactured outside of Japan. Please understand that they do not conform to the "Japanese Vehicle Inspection System," and we are unable to provide documents such as strength calculation reports for Japanese vehicle inspection purposes. Therefore, all parts are sold for the purpose of "use on circuits, private property, 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 Japan, there may be shipping damage to the packing box or the product. Please understand that we will only provide returns, refunds, or replacement exchanges if you contact us within 7 days of receipt regarding products with shipping damage, defective products, or products different from what was ordered. Furthermore, regarding products sold through us, we will provide warranty support "only through us." Please note that we do not provide support through other companies or distributors located in Japan.
