Before You Order

〇 Regarding Import Consumption Tax
At the Shaftoya shopping site, we pay the import consumption tax incurred at the time of import on your behalf, so there are no additional charges beyond the total amount paid at checkout.

Confirmation of Compatibility
Our entire product database is based on North American vehicles (USDM vehicles), so please check whether or not installation on Japanese vehicles (JDM vehicles) is possible 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 you order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, make, and vehicle model in the tabs on our homepage, 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.

○ Regarding Shipping
Shipping costs are paid at the time of payment. Estimates for shipping costs are calculated automatically when you enter your shipping address on the checkout page. For large items such as body parts, the automatically calculated shipping cost may occasionally differ significantly from the actual cost. In such cases, we will contact you individually via email.

Basically, all products are shipped internationally from our US warehouse. Unlike domestic shipping within 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. Please note that all products are transported by air; they are never shipped by sea freight.

○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products we handle are basically designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese vehicle inspection (Shaken) system" in any way, and we cannot provide strength evaluation documents or similar items for the Japanese Shaken 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.

○ Regarding Warranty
Please check the contents immediately upon arrival. As all products are shipped internationally from outside Japan, packaging boxes or products may sustain shipping damage. Please understand that we will only provide returns, refunds, or replacements for products with shipping damage, defective products, or products different from what was ordered if you contact us within 7 days of receipt. Please note that for products sold through us, we will handle warranty-related matters "exclusively through us." We do not provide support through other companies or distributors located within Japan.
