Before Ordering
〇 Regarding Import Consumption Tax
At Shaft-ya shopping site, we pay the import consumption tax incurred upon importation on your behalf, so you will not be charged any additional fees beyond the total amount paid at checkout.
〇Confirmation of Compatibility
All product databases are based on North American vehicles (USDM), so please check the compatibility with Japanese vehicles (JDM) before ordering. (If you are unsure if the listed product fits your vehicle, please feel free to contact us. Our support team will look it up 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, manufacturer, and vehicle 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. There may be confusing expressions, so 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 when 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 shipping cost. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow plenty of time for your order. If you are in a hurry, please inquire about delivery times in advance. Please note that all products are transported by air. No products are shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Basically, all products handled by our company are designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength evaluation documents or similar paperwork for this purpose. Therefore, all parts are sold for 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 of your order. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packing boxes or products. Please understand that we will only provide returns, refunds, or replacement items for damaged, defective, or incorrect items if notified within 7 days of receipt. Furthermore, for products sold through our company, warranty-related support will be handled "exclusively through us." Please note that we do not provide support through other companies or distributors located within Japan.
