Before Ordering
〇Regarding Import Consumption Tax
At Shafto-ya Shopping Site, we cover the import consumption tax incurred at the time of import, so there will be no additional charges beyond the total amount paid at checkout.
〇Confirmation of Compatibility
All of our product databases are based on North American vehicles (USDM), so please verify whether the item can be installed on a Japanese vehicle (JDM) before placing your order. (If you are unsure whether a listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to assist you.)
If you place an 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 guarantee that they will fit Japanese domestic models without modifications.
All product descriptions 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 once 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.
All products are generally shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, international shipping takes approximately 7 to 14 days, so please allow sufficient time for your order to arrive. If you are in a hurry, please contact us in advance to confirm the delivery time. Please note that all items 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 note that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide documents such as strength calculation reports for the Japanese inspection system. Therefore, all parts are sold for the purpose of "use on circuits, private property, and off-road" only; please install and use them at your own risk.
○Regarding Warranty
Please check the contents of your order immediately upon arrival. As all products are shipped internationally from outside of Japan, there is a possibility of shipping damage to the packaging or the product itself. Please understand that we will only provide returns, refunds, or replacements for products with shipping damage, defective items, or incorrect items if notified within 7 days of receipt. Furthermore, for products sold through our company, all 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.
