Before Ordering
〇 Regarding Import Consumption Tax
At Shaftoya Shopping Site, we cover the import consumption tax incurred at the time of import, so there are no additional charges beyond the total amount paid at checkout.
〇Confirmation of Compatibility
All product databases are based on North American vehicle specifications (USDM); please verify compatibility with Japanese specification vehicles (JDM) before ordering. (Please feel free to contact us if you are unsure whether a listed product is compatible with your vehicle. Our support team will be happy to assist you.)
Orders placed without verifying compatibility are not eligible for returns due to incompatibility.
Please note that even if items are sorted by year, make, and model using the tabs on our homepage, this does not guarantee a direct, modification-free fitment for Japanese market models.
All product descriptions are translated into Japanese using software. There may be confusing expressions, so 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 once you enter your delivery address on the checkout page. For large items such as body parts, the actual shipping cost may occasionally differ significantly from the automatic calculation. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our US warehouse. Unlike domestic Japanese shipping, international shipping takes approximately 7 to 14 days, so please allow ample time when ordering. If you are in a hurry, please contact us in advance to confirm the delivery date. Note that all products are transported by air. They are not shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Our products are primarily designed and manufactured outside of Japan. Please understand that they are not compliant with the "Japanese Vehicle Inspection System (Shaken)," and we cannot provide strength calculation documents or similar paperwork for these requirements. Therefore, all parts are sold for "track, private property, or off-road use only," 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 is a possibility of shipping damage to the packaging or the product itself. Please understand that we will only provide returns, refunds, or exchanges for products with shipping damage, defects, or incorrect items if notified within 7 days of receipt. Please also note that for products sold through us, warranty support will be handled "exclusively through us." We do not coordinate with other companies or domestic agencies within Japan for warranty claims.
