Before Ordering
〇 Regarding Import Consumption Tax
At the 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Confirmation of Compatibility
Our entire product database is based on North American vehicles (USDM), so please confirm whether the product can be installed on a Japanese vehicle (JDM) before ordering. (If you are unsure if a listed product fits your vehicle, please feel free to contact us. Our support team will be happy to check 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 via 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 with any questions before placing your order.
○ Regarding Shipping
Shipping costs are paid at the time of checkout. Shipping estimates are calculated automatically once you enter your shipping address on the checkout page. For large items such as body parts, there are rare cases where the automatically calculated shipping fee differs significantly from the actual cost. In such instances, we will contact you individually via email.
All products are generally shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes 7 to 14 days, so please allow ample time when ordering. If you are in a hurry, please contact us in advance to confirm delivery times. Please note that all products are transported by air. They will not be shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Please be aware that all products we handle are designed and manufactured outside of Japan. They are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength evaluation documents or similar paperwork for these purposes. Therefore, all parts are sold for the purpose of "use on circuits, private property, or off-road," and installation and usage 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 itself. Please understand that we will only provide returns, refunds, or replacements for damaged items, defective products, or incorrect items if notified within 7 days of receipt. Furthermore, for products sold through us, warranty-related support will be handled "exclusively through us." Please note that we do not handle support through other companies or distributors located within Japan.
