Before Ordering
〇 Regarding Import Consumption Tax
At the Shafutoya shopping site, we cover 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
As our entire product database is based on North American vehicles (USDM), please confirm compatibility with Japanese 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 investigate 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, 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 if you have any questions before ordering.
○ Regarding Delivery
Shipping costs are paid at the time of settlement. An estimate for shipping costs will be automatically calculated on the checkout page once you enter your shipping address. For large items such as body parts, the actual shipping cost may occasionally differ significantly from the amount automatically calculated. In such cases, we will contact you individually via email.
Essentially, all products are shipped internationally from our US warehouse. Unlike domestic delivery within Japan, international shipping takes approximately 7 to 14 days, so please allow sufficient time for your order. If you are in a hurry, please contact us in advance to confirm the delivery date. All products are transported via air freight. They are not shipped via sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
The products we handle are fundamentally designed and manufactured outside of Japan. Please be aware that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength calculation documents or similar paperwork for the purpose of such inspections. Consequently, all parts are sold for use on "circuits, private property, or off-road use only," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents immediately upon receipt of your product. As all products are shipped internationally from outside Japan, there may be instances of shipping damage to packaging boxes or the products themselves. Please understand that we will only provide returns, refunds, or replacements for products with shipping damage, defective items, or items different from what was ordered 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 be aware that we do not provide support through other companies or distributors located within Japan.
