Before You Order
〇 Regarding Import Consumption Tax
At Shaftoya shopping site, we cover the import consumption tax incurred at the time of import, so there will be no additional charges beyond the total amount paid at checkout.
〇 Compatibility Verification
As our product database is based primarily on North American vehicles (USDM), please confirm compatibility with Japanese domestic vehicles (JDM) before placing your order. (If you are unsure if 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.
Please note that even if products are sorted by year, make, and model using the tabs on our homepage, it does not necessarily guarantee that they will fit Japanese models without modification.
All product descriptions are 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 payment. Shipping estimates are calculated automatically when you enter your shipping address on the checkout page. For large items such as body parts, there may occasionally be a significant discrepancy between the automatically calculated shipping cost and the actual cost. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, international shipping takes approximately 7 to 14 days, so please allow sufficient time when ordering. If you are in a hurry, please contact us in advance to confirm the delivery date. Please note that all products are transported by air; they are not shipped by sea.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Please be aware that all products we handle are designed and manufactured outside of Japan. They are not compliant with the "Japanese Vehicle Inspection (Shaken) System," and we are unable to provide strength evaluation documents for this system. Therefore, all parts are sold for use on circuits, private land, or off-road, and their installation and use are at your own risk.
○ Regarding Warranty
Please inspect the contents immediately upon delivery. As all products are shipped internationally from outside Japan, packaging or products may sustain shipping damage. Please understand that we will only provide returns, refunds, or replacements for damaged items, defective products, or incorrect items if notified within 7 days of receipt. Furthermore, for all products sold through us, warranty-related support will be provided "exclusively through our company." Please note that we cannot offer support through other companies or distributors based in Japan.
