Before You Order
〇 Regarding Import Consumption Tax
At Shaftoya Shopping Site, we pay 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Checking Compatibility
Since all product databases are based on North American vehicles (USDM), please confirm compatibility with Japanese vehicles (JDM) before ordering. (If you are unsure whether the listed product is compatible with your vehicle, please feel free to contact us. Our support team will look into it for you.)
If you order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by selecting the year, make, and model on our top page tabs, it 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 before ordering if you have any questions.
○ 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, the actual shipping cost may occasionally differ significantly from the automated calculation. In such cases, we will contact you individually via email.
In principle, all products are shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please order with enough time to spare. If you are in a hurry, please contact us in advance to check delivery times. Note that all products are transported by air. They are not shipped by sea.
○ Regarding Japanese Vehicle Inspection Compliance
Products handled by our company are basically designed and manufactured outside of Japan. Please understand that they do not conform to "Japanese vehicle inspection standards," and we cannot provide documents such as strength calculation sheets for Japanese inspection purposes. Therefore, all parts are sold for use on "circuits, private property, and off-road" purposes, 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. For products with shipping damage, defective products, or items different from your order, we will provide returns, refunds, or replacement exchanges only if you contact us within 7 days of receipt. Please understand that for products sold through our company, warranty-related support will be handled "exclusively through us." We do not provide support through other companies or distributors located within Japan.
