Before Ordering
○ About Import Consumption Tax
At Shafto-ya 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.
○ Compatibility Confirmation
Since all product databases are based on North American vehicles (USDM), please verify compatibility with Japanese vehicles (JDM) before placing your order. (If you are unsure if a listed product fits your vehicle, please feel free to contact us. Our support team will check it for you.)
If you order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by selecting the year, manufacturer, and vehicle model via the tabs on our homepage, it does not necessarily mean they will fit Japanese models 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 payment. Shipping estimates are automatically calculated when you enter your shipping address on the checkout page. For large items such as body parts, the automatically calculated shipping fee may rarely differ significantly from the actual cost. In such cases, we will contact you individually via email.
Basically, all products are shipped internationally from our warehouse in the U.S. Unlike domestic shipping within Japan, international shipping takes about 7 to 14 days, so please order with 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 freight; they are never shipped by sea.
○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
The products we handle are basically all designed and manufactured outside of Japan. Please be aware that they are not compliant with the "Japanese Vehicle Inspection (Shaken) system," and we are unable to provide strength calculation documents for the Japanese Shaken system. Therefore, all parts are sold for the purpose of "use at 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 of Japan, there may be shipping damage to the packaging or the product itself. Please understand that we will only provide returns, refunds, or replacement exchanges for items with shipping damage, defective products, or incorrect items if contacted within 7 days of receipt. Please note that for products sold through us, warranty-related support will be provided "only through us." Support through other domestic companies or agencies in Japan is not provided.
