Before Placing an Order

〇 Regarding Import Consumption Tax
At 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 beyond the total amount paid at checkout.

Confirmation of Compatibility
Our entire product database is based on North American vehicles (USDM), so please confirm compatibility with Japanese vehicles (JDM) before placing your order. (If you are unsure whether the listed product will fit your vehicle, please feel free to contact us. Our support team will be happy to assist you.)
If you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by selecting the year, make, and model in the tabs on our top page, this does not necessarily guarantee that they will fit Japanese model vehicles without modification.
All product descriptions are translated into Japanese using translation software. As there may be confusing expressions, 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 once 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 cost. In such cases, we will contact you individually via email.

All products are fundamentally shipped internationally from our U.S. warehouse. Unlike domestic shipping within Japan, international shipping 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. Please note that all products are transported by air. They are not shipped by sea freight.

○ Regarding Japanese Vehicle Inspection (Shaken) Compliance
Please be aware that all products we handle are designed and manufactured outside of Japan. They are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength study reports or similar documentation for Japanese inspection purposes. Therefore, all parts are sold for use on "circuits, private land, or off-road," and you are responsible for their installation and use.

○ Regarding Warranty
Please check the contents of your order immediately upon arrival. Since all products are shipped internationally from outside Japan, there is a possibility that packaging boxes or products may sustain shipping damage. Please understand that we will only provide returns, refunds, or exchanges for products with shipping damage, defective products, or incorrect items if notified within 7 days of receipt. Additionally, for products sold through our company, all warranty-related matters will be handled "exclusively through us." Please note that we do not provide support through other companies or distributors located within Japan.
