Before You Order
〇Regarding Import Consumption Tax
At the Shaftoya shopping site, we pay the import consumption tax incurred upon importation on your behalf, so you will not be charged any additional fees beyond the total amount paid at checkout.
〇Compatibility Check
All product databases are based on North American (USDM) vehicles; please check whether the product can be installed on a Japanese (JDM) vehicle before ordering. (If you are unsure whether the listed product is compatible with your vehicle, please feel free to contact us. Our support team will look into it for you.)
If you order without verifying compatibility, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by selecting the year, make, and model on the tabs on our top page, it does not necessarily guarantee that they will fit Japanese model vehicles without modification.
All products have been 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 fees 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 sometimes differ significantly from the amount calculated automatically. In such cases, we will contact you individually via email.
Basically, all products are shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 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. They are never shipped by sea.
○Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products we handle are basically designed and manufactured outside of Japan. Please understand that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength evaluation documents or similar items for the Japanese inspection system. Therefore, all parts are sold for "use on circuits, private land, or off-road," and installation and use are at your own risk.
○Regarding Warranty
Please check the contents immediately upon arrival. As all products are shipped internationally from outside Japan, the packaging or product may sustain shipping damage. Please understand that we will only provide returns, refunds, or replacement exchanges for items with shipping damage, defective products, or incorrect items if you contact us 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.
