Before placing your order
〇 About Import Consumption Tax
At the Shaftoya shopping site, we pay the import consumption tax incurred at the time of import on your behalf, so there will be no additional charges other than the total amount paid at checkout.
〇Checking Compatibility
As our entire product database is based on North American vehicles (USDM), please confirm whether or not these products can be installed on Japanese domestic vehicles (JDM) before ordering. (If you are unsure whether 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 compatibility, we cannot accept returns due to incompatibility.
Please note that even if you have sorted products by selecting the year, manufacturer, and vehicle model in the tabs on our top page, this 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 if you have any questions, please contact us before ordering.
○ Regarding Shipping
Shipping costs are paid at the time of checkout. Shipping estimates are automatically calculated once you enter your delivery 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.
Basically, all products are shipped internationally from our US warehouse. Unlike domestic Japanese shipping, 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 to check delivery times in advance. All products are transported by air. They are not shipped by sea.
○ Regarding Japanese Vehicle Inspection Compliance
Basically, all products we handle are designed and manufactured outside of Japan. Please note that they do not conform to the "Japanese vehicle inspection system" in any way, and we cannot provide strength calculation documents or similar materials for the purpose of such inspections. Therefore, all parts are sold for use on "circuits, private property, or off-road," and please install and use them at your own risk.
○ Regarding Warranty
Please check the contents of your order immediately upon arrival. As all products are shipped internationally from outside Japan, packaging boxes and products may sustain damage during transit. Please understand that we will only provide returns, refunds, or replacements for products with transit damage, defective products, or incorrect items if you contact us within 7 days of receipt. Please note that for products sold through us, we will handle all warranty-related issues "exclusively through us." We do not coordinate with other companies or agencies located within Japan.
