Before Ordering
〇 Regarding Import Consumption Tax
At Shaft-ya Shopping Site, we cover the import consumption tax incurred at the time of import on your behalf, so you will not be charged any additional fees beyond the total amount paid at checkout.
〇Confirmation of Fitment
As our product database is primarily based on North American vehicles (USDM), please confirm whether the product can be installed on a Japanese domestic vehicle (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 look into it for you.)
If you place an order without confirming fitment, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by selecting the year, manufacturer, and vehicle model using the tabs on our homepage, this does not necessarily mean they will fit Japanese market vehicles without modification.
All product descriptions have been translated into Japanese using translation software. Due to the possibility of confusing expressions, please contact us before ordering if you have any questions.
○ Regarding Shipping
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 actual shipping cost may occasionally differ significantly from the amount calculated automatically. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our US warehouse. Unlike domestic shipping within Japan, international delivery takes approximately 7 to 14 days, so please allow sufficient time when placing your order. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all products are transported by air; they are not shipped by sea.
○ Regarding Japanese Vehicle Inspection (Shaken) Compliance
All products handled by our company are generally designed and manufactured outside of Japan. Please be aware that they are not compliant with the "Japanese Vehicle Inspection System," and we are unable to provide strength calculation documents or similar paperwork for these regulations. Therefore, all parts are sold for the purpose of "use on tracks, private property, or off-road," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents of your package immediately upon arrival. Since all products are shipped internationally from outside Japan, there is a possibility of shipping damage to the packaging or the product itself. Please understand that we will only provide returns, refunds, or replacements for damaged, defective, or incorrect items if notified within 7 days of receipt. Furthermore, regarding products sold through our company, all warranty-related support will be handled "exclusively through our company." Please note that we cannot provide support through other companies or distributors located in Japan.
