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Confirmation of Compatibility
Our entire product database is based on North American vehicles (USDM). Please confirm whether or not these parts can be installed on Japanese market vehicles (JDM) before placing your order. (If you are unsure whether a 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.
Furthermore, please note that even if products are sorted by selecting the year, manufacturer, and vehicle model in 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. 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 on the checkout page once you enter your shipping address. 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 within Japan, international shipping takes approximately 7 to 14 days, so please allow yourself plenty of time when ordering. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all products are transported by air freight; they are never shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
The products we handle are basically all 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 or similar paperwork for these inspections. Therefore, all parts are sold for the purpose of "circuit, private property, or off-road use," and any installation or use is at your own risk.
○ Regarding Warranty
Please inspect the contents immediately upon delivery. As all products are shipped internationally from outside Japan, there is a possibility that shipping damage may occur to the packaging or the product itself. Please understand that we will only provide returns, refunds, or replacement exchanges for items with shipping damage, defective products, or items different from your order if you contact us within 7 days of receipt. Please note that for products sold through us, warranty support will be provided "exclusively through us." We do not provide support through other companies or distributors located within Japan.
