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 Confirmation of Compatibility
Since our entire product database is based on North American vehicle specifications (USDM), please confirm whether the product 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.)
If an order is placed without verifying compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, make, and model using the tabs on our homepage, it does not necessarily mean they will fit Japanese model vehicles without modification.
All product descriptions are 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 cost. In such cases, we will contact you individually via email.
In principle, 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 plenty of time when placing your order. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all products are transported by air; they are never shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Basically, all products we handle are designed and manufactured outside of Japan. Please understand that they are not adapted to the "Japanese vehicle inspection (Shaken) system" in any way, and we cannot provide strength evaluation documents or similar paperwork 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 Japan, there may be shipping damage to the packaging or the product itself. Please understand that for products with shipping damage, defective products, or items different from your order, we will only handle returns, refunds, or exchanges if notified within 7 days of receipt. Additionally, for products sold through us, warranty support will be handled "only through us." Please note that we do not handle support through other companies or distributors located within Japan.
