Before Ordering
〇 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.
〇Confirmation of Compatibility
Since our entire product database is based on North American vehicles (USDM), please confirm compatibility with Japanese domestic vehicles (JDM) before placing your order. (If you are unsure whether a listed product fits your vehicle, please feel free to contact us. Our support team will investigate for you.)
If you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, make, and model from the tabs on our top page, this does not necessarily mean they will fit Japanese models without modification.
All products 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 Delivery
Shipping costs are paid at the time of checkout. Shipping estimates are automatically calculated 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 automated calculation. In such cases, we will contact you individually via email.
Essentially, all products are shipped internationally from our US warehouse. Unlike domestic Japanese shipping, international shipping takes approximately 7 to 14 days, so please allow sufficient time when ordering. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all items are shipped via air freight; we do not use sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products handled by our company are essentially designed and manufactured outside of Japan. Please be aware that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength calculation documents or similar paperwork for these requirements. Therefore, all parts are sold for use on "circuits, private land, or off-road use only," 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 Japan, there may be instances of damage to the shipping box or the product itself. We will handle returns, refunds, or exchanges only if you contact us within 7 days of receipt regarding items with shipping damage, defective products, or incorrect items. Please note that for products sold through our company, we provide warranty support "exclusively through us." We do not provide support through other companies or distributors located within Japan.
