Before placing your order
〇Regarding Import Consumption Tax
At the Shaftoya shopping site, we cover 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
Our entire product database is based on North American vehicles (USDM). Please confirm whether or not these products can be installed on Japanese vehicles (JDM) before ordering. (If you are unsure if a listed product is compatible with your vehicle, please feel free to contact us. Our support team will investigate 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, manufacturer, and vehicle model via the tabs on our top page, this does not necessarily mean 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 before ordering if you have any questions.
○Regarding Shipping
Shipping costs are paid at the time of checkout. Shipping estimates are calculated automatically on the checkout page once you enter your shipping address. For large items such as body parts, the automatic shipping calculation may occasionally differ significantly from the actual shipping cost. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes approximately 7 to 14 days, so please allow plenty of time for your order. If you are in a rush, please contact us in advance to confirm delivery times. Note that all items are shipped via air freight. They are not shipped via sea freight.
○Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Please note that all products we handle are designed and manufactured outside of Japan. They are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength evaluation documents or similar paperwork for the purpose of the Japanese vehicle inspection system. 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 of your order immediately upon arrival. As all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product itself. We will only provide returns, refunds, or replacement exchanges for products with shipping damage, defective products, or items different from what was ordered if you contact us within 7 days of receipt. Please understand that for products sold through us, we will handle all warranty-related matters "exclusively through us." We do not handle matters through other companies or distributors located within Japan.
