Before placing an order
〇Regarding import consumption tax
At the Shaftoya shopping site, we cover 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.
〇Compatibility confirmation
Our entire product database is based on North American vehicle specifications (USDM); please verify whether the items can be installed on Japanese domestic vehicles (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 look into it for you.)
Please note that if you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Additionally, even if products are sorted after selecting the year, manufacturer, and vehicle model using the tabs on our home page, please understand that this does not necessarily guarantee fitment on Japanese-model vehicles without modification.
All products have been translated into Japanese using translation software. As there may be confusing expressions, please contact us if you have any questions before ordering.
○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 cost. In such cases, we will contact you individually via email.
Basically, all products are shipped internationally from our US warehouse. Unlike domestic shipping within Japan, international delivery takes approximately 7 to 14 days, so please allow sufficient time when placing your order. If you are in a hurry, please contact us to confirm the lead time in advance. Please note that all products are transported by air; they are never shipped by sea freight.
○Regarding Japanese vehicle inspection (Shaken) compliance
Please be aware that all products we handle are fundamentally designed and manufactured outside of Japan. They are not compliant with the "Japanese vehicle inspection system," and we are unable to provide strength study documents or similar certification 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 of Japan, there may be instances of shipping damage to the packaging or the product itself. Please understand that we will only provide returns, refunds, or replacement products for items with shipping damage, defective goods, or items different from those ordered if you contact us within 7 days of receipt. Furthermore, for products sold through our company, warranty-related support will be handled "exclusively through us." Please note that we do not provide support through other companies or distributors located within Japan.
