Before Placing an Order
〇 About Import Consumption Tax
At the Shaftoya shopping site, we pay 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 Check
As our entire product database is based on North American vehicles (USDM), please confirm the compatibility with Japanese vehicles (JDM) before placing your order. (If you are unsure whether the 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 you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by selecting the year, manufacturer, and vehicle model on the tabs of our homepage, this does not necessarily mean they will fit Japanese-model vehicles without modifications.
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 fees 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, the actual shipping cost may occasionally differ significantly from the automated calculation. In such cases, we will contact you individually by email.
All products are generally shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please place your order with enough time to spare. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all items are shipped by air; they are never shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products we handle are designed and manufactured outside of Japan. Please be aware that they are not compliant with "Japanese vehicle inspection standards," and we cannot provide strength calculation documents for Japanese inspection purposes. Therefore, all parts are sold for 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 items are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product. We will only provide returns, refunds, or replacements for shipping-damaged items, defective products, or incorrect items if you contact us within 7 days of receipt. Please understand that for products sold through our company, warranty support will be handled "exclusively through us." We do not provide support through other companies or distributors located within Japan.
