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 you will not be charged any additional fees beyond the total amount paid at checkout.
〇Compatibility Check
As our entire product database is based on North American vehicles (USDM), please confirm whether the item is compatible with your Japanese vehicle (JDM) before ordering. (If you are unsure if a listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to look into it for you.)
If you order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, make, and model on our homepage tabs, 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 calculated automatically when you enter your shipping address on the checkout page. For large items such as body parts, there may occasionally be a significant discrepancy 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 place your order with sufficient time. If you are in a hurry, please contact us in advance to confirm the delivery date. Note that all products are transported by air. They are not shipped by sea.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products we handle are basically designed and manufactured outside of Japan. Please be aware that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide documents such as strength evaluation reports for the Japanese inspection system. 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. As 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 items with shipping damage, defective products, or incorrect items if you contact us within 7 days of receipt. Furthermore, for products sold through us, warranty support will be provided "only through us." Please note that we do not handle support through other companies or distributors located within Japan.
