Before You Order
〇 Regarding Import Consumption Tax
At the 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.
〇 Compatibility Verification
As our entire product database is based on North American vehicles (USDM), please confirm whether parts can be installed on Japanese domestic vehicles (JDM) before placing your order. (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 assist you.)
If an order is placed without verifying compatibility, 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 homepage, it does not necessarily guarantee that they will fit Japanese model vehicles without modification.
All product descriptions 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 checkout. Shipping estimates are calculated automatically once you enter your shipping address on the checkout page. For large items such as body parts, there are rare cases where the automatically calculated shipping fee differs significantly from the actual cost. In such instances, we will contact you individually via email.
Basically, all products are shipped internationally from our US warehouse. Unlike domestic Japanese shipping, international shipping takes approximately 7 to 14 days, so please allow ample time when ordering. If you are in a hurry, please contact us in advance to check the delivery time. Please note that all products are transported by air; they are not shipped by sea.
○ Regarding Japanese Vehicle Inspection (Shaken) Compliance
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 documents such as strength test reports for Japanese vehicle inspections. Therefore, all parts are sold for "use on tracks, private land, or off-road," and installation and use are at your own risk.
○ Regarding Warranty
Please inspect the contents immediately upon arrival. Since all products are shipped internationally from outside of Japan, there may be shipping damage to the packaging or the products themselves. Please understand that we will only provide returns, refunds, or exchanges for shipping-damaged items, defective products, or incorrect items if you notify us within 7 days of receipt. Additionally, for products sold through us, all warranty-related matters will be handled "exclusively through us." Please be aware that we do not facilitate processing through other companies or distributors located within Japan.
