Before You Order
〇 Regarding Import Consumption Tax
At Shaftoya 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 Compatibility
Our entire product database is based on North American vehicles (USDM). Please confirm compatibility with Japanese vehicles (JDM) before placing your order. (Please feel free to contact us if you are unsure whether the listed product will fit your vehicle. Our support team will be happy to look it up for you.)
If you place an order without confirming compatibility, we cannot accept returns due to non-compatibility.
Please note that even if products are sorted by selecting the year, manufacturer, and vehicle model on 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. As there may be confusing expressions, please contact us before ordering if you have any questions.
○ Regarding Delivery
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 there is 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 shipping in Japan, international shipping takes approximately 7 to 14 days, so please allow yourself plenty of time when ordering. If you are in a hurry, please contact us in advance to check the delivery time. Note that all products are transported by air; they are never shipped by sea freight.
○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
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 are unable to provide documents such as strength examination reports for the Japanese inspection system. Therefore, all parts are sold for the purpose of "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. As all products are shipped internationally from outside Japan, there may be delivery damage to the packaging boxes or products. Please understand that we will only provide returns, refunds, or replacements for products with delivery damage, defective items, or items different from your order if you contact us within 7 days of receipt. Please note that for products sold through our company, warranty support will be provided "only through us." We do not provide support through other companies or distributors located in Japan.
