Before Ordering

〇 Regarding Import Consumption Tax
At the Shaftoya shopping site, we cover the import consumption tax incurred at the time of import, so you will not be charged any additional fees beyond the total amount paid at checkout.

Compatibility Confirmation
All of our product databases are based on North American vehicles (USDM). Please confirm whether or not they can be installed on Japanese vehicles (JDM) 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 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 selecting the year, manufacturer, and vehicle model using the tabs on our top page, this does not necessarily mean 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 if you have any questions before placing your order.

〇 Regarding Shipping
Shipping costs are paid at the time of checkout. Shipping estimates are automatically calculated once you enter your shipping address on the checkout page. For large items such as body parts, there may be rare cases where the automatically calculated shipping cost differs significantly from the actual cost. In such cases, we will contact you individually via email.

Basically, all products are shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow 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; we do not use sea freight.

〇 Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Please note that all products we handle are designed and manufactured outside of Japan. They are not adapted to Japan's "Vehicle Inspection System," and we cannot provide strength evaluation documents or similar paperwork for the Japanese inspection system. Therefore, all parts are sold for the purpose of "use on circuits, private property, or off-road," and installation and use are at your own risk.

〇 Regarding Warranty
Please check the contents of your order immediately upon arrival. As all products are shipped internationally from outside of Japan, packaging boxes and products may sustain damage during transit. Please understand that we will only provide returns, refunds, or replacement items for products with shipping damage, defective products, or incorrect items if you notify us within 7 days of receipt. Furthermore, for products sold through our company, warranty support will be handled "exclusively through our company." Please note that we do not handle support through other companies or distributors located within Japan.
