Before You Order
〇 Regarding Import Consumption Tax
At Shaftoya Shopping Site, we cover 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
Since 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 a listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to assist you.)
If an order is placed without confirming compatibility, we cannot accept returns due to non-compatibility.
Please note that even if items are sorted by selecting the year, manufacturer, and vehicle model using the tabs on our top page, this does not necessarily mean they will fit Japanese market vehicles without modification.
All products have been translated into Japanese using translation software. Due to potential discrepancies in wording, 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 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 via email.
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 ample time when ordering. If you are in a rush, please contact us to confirm the delivery date in advance. Please note that all products are transported by air; they are not shipped via sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products handled by our company are designed and manufactured outside of Japan. Please be aware that these products are not compliant with the "Japanese Vehicle Inspection System (Shaken)," and we cannot provide documentation such as strength calculation reports for Japanese inspection purposes. Therefore, all parts are sold for the purpose of "use on tracks, private property, or off-road," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents immediately upon delivery. As all products are shipped internationally from outside Japan, there may be instances of shipping damage to the packaging or the product. Please understand that we will only provide returns, refunds, or replacements for damaged, defective, or incorrect items if notified within 7 days of receipt. Furthermore, for products sold through us, all warranty-related support will be handled "exclusively through our company." Please note that we do not coordinate with other companies or agencies located within Japan.
