Before Ordering
〇 Regarding Import Duties and Taxes
At Shaftoya, we cover the import consumption taxes incurred during customs clearance, so there are no additional charges beyond the total amount paid at checkout.
〇Confirmation of Fitment
Our product database is based on North American market (USDM) vehicles. Please verify whether the product is compatible with Japanese market (JDM) vehicles 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 be happy to check for you.)
If an order is placed without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if a product appears after filtering by year, make, and model on our top page, it does not necessarily guarantee a direct, bolt-on fitment for Japanese market vehicles without modification.
All product descriptions have been translated into Japanese using translation software. As there may be confusing expressions, please contact us if you have any questions before placing your order.
○ Regarding Shipping
Shipping costs are paid at the time of checkout. Shipping estimates are calculated automatically upon entering 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.
All products are generally shipped internationally from our US warehouse. Unlike domestic Japanese shipping, international delivery typically takes 7 to 14 days, so please allow sufficient time when placing your order. If you require expedited shipping, please contact us in advance to confirm delivery times. Note that all products are transported by air freight; they are never shipped via sea freight.
○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
All products we handle are designed and manufactured outside of Japan. Please understand that they do not conform to "Japanese Vehicle Inspection (Shaken)" standards, and we cannot provide structural analysis documents or similar paperwork for these purposes. Consequently, all parts are sold for "circuit use, private property, or off-road use," and installation and usage are at the customer's own risk.
○ Regarding Warranty
Please inspect the contents immediately upon arrival. As all products are shipped internationally from outside Japan, packaging and products may sustain shipping damage. We will only provide returns, refunds, or replacement products if you contact us within 7 days of receipt regarding shipping damage, defective products, or incorrect items. Please note that for products sold through us, warranty support will be handled "exclusively through us." We do not coordinate with other companies or agencies based in Japan for warranty claims.
