Before Ordering
〇 Regarding Import Consumption Tax
At Shaft-ya Shopping Site, we cover 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Compatibility Confirmation
Our product database is based on North American specification vehicles (USDM). Please confirm compatibility with Japanese specification vehicles (JDM) before placing your order. (If you are unsure whether a listed product fits your vehicle, please feel free to contact us. Our support team will be happy to assist 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, this does not necessarily guarantee that 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 if you have any questions before placing your order.
○ 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 cost. In such cases, we will contact you individually via email.
Basically, all products are 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 delivery when placing your order. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all items are shipped via air freight; we do not use 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 are unable to provide strength study documents or similar for that purpose. Therefore, all parts are sold for "use on circuits, private property, or off-road," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, there is a possibility of shipping damage to the packaging or the product. Please understand that we will only provide returns, refunds, or replacements for damaged items, defective products, or items different from your order if you contact us within 7 days of receipt. Furthermore, regarding products sold through us, all warranty-related support will be handled "exclusively through us." Please note that we do not coordinate with other companies or agencies located within Japan.
