Before Ordering

○ Regarding Import Consumption Tax
At Shaft-Ya 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 Fitment
Since our entire product database is based on North American vehicles (USDM), please confirm whether the product can be installed on a Japanese vehicle (JDM) before placing your order. (If you are unsure if the listed product is compatible with your vehicle, please feel free to contact us. Our support team will check it for you.)
If you place an order without confirming fitment, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, make, and model using the tabs on our top page, it 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 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. For large items such as body parts, there may occasionally be a significant discrepancy between the automatically calculated shipping cost and 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 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 check the delivery time. Note that all products are transported by air. They are not shipped by sea freight.

○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products we handle are designed and manufactured outside of Japan. Please understand that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength calculation documents or similar paperwork for the Japanese inspection system. Therefore, all parts are sold for the purpose of "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. Since all products are shipped internationally from outside of Japan, there may be shipping damage to the packaging box or the product itself. Please understand that for products with shipping damage, defective products, or products different from what was ordered, we will only accept returns, refunds, or exchanges if notified within 7 days of receipt. Please note that for products sold through our company, warranty support will be provided "only through us." We do not provide support through other companies or distributors located within Japan.
