Before placing an 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.
〇 Confirmation of compatibility
All product databases are based on North American vehicles (USDM). Please confirm whether or not parts can be installed on Japanese vehicles (JDM) before ordering. (If you are unsure whether 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 order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the model year, manufacturer name, and vehicle model in 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 before ordering if you have any questions.
○ Regarding delivery
Shipping costs are paid at the time of payment. Shipping estimates 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.
In principle, 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 sufficient time for delivery. If you are in a hurry, please contact us in advance to check the lead time. Note that all products are transported by air freight; they are not shipped by sea freight.
○ Regarding Japanese vehicle inspection (Shaken) compliance
The products we handle are basically all designed and manufactured outside of Japan. Please note that they do not comply with the "Japanese vehicle inspection system" (Shaken), and we cannot provide strength evaluation reports 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.
○ Regarding warranty
Please check the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, there may be damage to the packaging or the product due to shipping. Please understand that we will only provide returns, refunds, or replacement products if you contact us within 7 days of receipt regarding items with shipping damage, defective products, or items different from what was ordered. Furthermore, regarding products sold through us, we will handle all warranty matters "exclusively through us." Please note that we do not provide support through other companies or agencies located in Japan.
