Before You Order
〇 About Import Taxes
Shafutoya Shopping Site covers the import taxes incurred during international shipping, so there will be no additional charges beyond the total amount paid at checkout.
〇 Checking Compatibility
Our entire product database is based on North American (USDM) specifications. Please confirm compatibility with your Japanese (JDM) vehicle before ordering. (If you are unsure if the listed product fits your vehicle, please feel free to contact us. Our support team will be happy to look into it for you.)
If an order is placed without verifying compatibility, we cannot accept returns due to fitment issues.
Please note that even if a product is sorted by year, make, and model using the tabs on our homepage, it does not necessarily guarantee fitment on Japanese models without modification.
All products have been translated into Japanese using translation software. If there are any confusing expressions, please contact us before placing your order.
○ Regarding Shipping
Shipping costs are paid at the time of checkout. Shipping estimates are automatically calculated when you enter your delivery address at checkout. For large items like body parts, there may occasionally be a significant discrepancy between the automatically calculated shipping cost and the actual cost. In such cases, we will contact you individually via email.
Basically, all products are shipped internationally from our warehouse in the United States. Unlike domestic shipping 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 inquire about delivery times in advance. Note that all items are shipped via air freight; we do not use sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Please note that all products we handle are designed and manufactured outside of Japan. They are not compliant with "Japanese vehicle inspection standards," and we cannot provide strength evaluation documents for the Japanese inspection system. Therefore, all parts are sold for "use on tracks, private property, or off-road," and any installation or use is at your own risk.
○ Regarding Warranty
Please check the contents immediately upon arrival. As all products are shipped internationally, there may be shipping damage to the packaging or the product itself. In the case of damaged goods, defective items, or items different from what was ordered, we will only handle returns, refunds, or replacements if notified within 7 days of receipt. Please understand that for products sold through us, all warranty support will be handled "exclusively through us." We do not provide support through other companies or distributors located within Japan.
