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 you will not be charged any additional fees beyond the total amount paid at checkout.
〇Compatibility Check
Our entire product database is based on North American vehicles (USDM), so please verify 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 and our support team will check it for you.)
If you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by year, make, and model using the tabs on our top page, this does not necessarily mean they will fit Japanese model vehicles without modification.
All product information is translated into Japanese using translation software. There may be confusing expressions, so 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 via email separately.
In principle, all products are 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 hurry, please contact us in advance to confirm delivery times. Note that all products are transported by air; sea freight is not used.
○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
The products we handle are designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese Vehicle Inspection (Shaken) system," and we cannot provide strength calculation documents for that purpose. Therefore, all parts are sold for the purpose of "circuit, private property, or off-road use," and installation and usage are at your own risk.
○ Regarding Warranty
Please check the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product. We will only provide returns, refunds, or exchanges for products with shipping damage, defective goods, 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.
