Before You Order
〇Regarding Import Consumption Tax
At Shaftoya Shopping Site, we pay any import consumption tax incurred during customs clearance on your behalf. Therefore, you will not be charged any additional fees beyond the total amount paid at checkout.
〇Verification of Compatibility
Our entire product database is based on North American market (USDM) vehicles. Please verify compatibility with your Japanese market (JDM) vehicle before placing your order. (If you are unsure whether a listed product fits your vehicle, please feel free to contact us. Our support team will be happy to look into it for you.)
If an order is placed without verifying compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are filtered by selecting the year, make, and model on our homepage, it does not guarantee that they will fit your Japanese model vehicle without modification.
All product descriptions have been translated into Japanese using software. As some expressions may be confusing, 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. In rare cases for large items such as body parts, there may be a significant discrepancy between the automatically calculated shipping cost and the actual shipping cost. In such cases, we will contact you individually via email.
In principle, all items are shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, international shipping takes approximately 7 to 14 days, so please allow ample time for delivery. If you are in a hurry, please contact us to confirm the lead time before ordering. Please note that all items are shipped via air freight. We do not use sea freight.
○Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products we handle are fundamentally designed and manufactured outside of Japan. Please be aware that they are not compliant with the "Japanese Vehicle Inspection System," and we are unable to provide strength verification documents or similar paperwork for these inspections. Consequently, all parts are sold for the purpose of "use on circuits, private property, and off-road," and installation and use are at your own risk.
○Regarding Warranties
Please inspect the contents immediately upon arrival. As all items are shipped internationally from outside Japan, there is a possibility of shipping damage to the packaging or the product itself. Please understand that we will only provide returns, refunds, or replacements for damaged items, defective products, or items different from what was ordered if you contact us within 7 days of receipt. Furthermore, for products sold through our company, all warranty-related support will be handled "exclusively through us." Please note that we do not provide support through other companies or distributors located in Japan.
