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 Compatibility
All of our product databases are based on North American vehicles (USDM). Please confirm whether or not a product can be installed on a Japanese vehicle (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 look it up 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 using the tabs on our top page, it does not necessarily mean they are compatible with Japanese-spec 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 fees are paid at the time of checkout. Shipping fee estimates are calculated automatically once you enter your shipping address on the checkout page. For large items such as body parts, the actual shipping cost may occasionally differ significantly from the amount calculated automatically. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our U.S. warehouse. Unlike domestic Japanese shipping, international shipping takes about 7 to 14 days, so please allow yourself enough time when ordering. If you are in a hurry, please contact us in advance to check the delivery time. Please note that all products are transported by air; they are never shipped by sea freight.
○Regarding Compliance with Japanese Vehicle Inspection (Shaken)
All products handled by us are basically designed and manufactured outside of Japan. Please note that they are not adapted to the "Japanese vehicle inspection system," and we cannot provide strength study reports or similar documentation for Japanese inspections. Therefore, all parts are sold for the purpose of "use on circuits, private land, or off-road," and installation and use are 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 itself. Please understand that we will only provide returns, refunds, or replacements for products with shipping damage, defective items, or items different from the order if you contact us within 7 days of receipt. Furthermore, for products sold through us, all warranty-related support will be handled "exclusively through us." Please note that we do not provide support through other companies or distributors located within Japan.
