Before Ordering
〇 Regarding Import Consumption Tax
At Shafutoya 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 Checking Compatibility
Our entire product database is based on North American vehicles (USDM). Please confirm whether the product is compatible with Japanese vehicles (JDM) before ordering. (If you are unsure whether a listed product fits 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 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. 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 checkout. Shipping estimates are automatically calculated when 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 automatically calculated. 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 delivery takes about 7 to 14 days, so please allow plenty of time when ordering. If you are in a hurry, please contact us in advance to confirm the delivery date. All products are transported by air; they are not shipped by sea.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
The products we handle are basically all designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese vehicle inspection system," and we cannot provide strength calculation documents or similar paperwork for this purpose. 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. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product. Please understand that we will only provide returns, refunds, or replacements for products with shipping damage, defective products, or incorrect items if you contact us within 7 days of receipt. Please note that for products sold through us, warranty-related support will be provided "only through our company." We do not provide support through other companies or distributors located within Japan.
