Before You Order
〇 About Import Consumption Tax
At Shaftoya 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
As our product database is based on North American vehicles (USDM), please verify compatibility with Japanese vehicles (JDM) before placing your order. (If you are unsure if a listed product fits 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 products are sorted by selecting the year, manufacturer, and model using the tabs on our top page, it does not necessarily guarantee a bolt-on fit for Japanese market vehicle models.
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 ordering.
○ About 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 the automatically calculated shipping cost differs significantly from the actual cost. In such cases, we will contact you individually by email.
All products are generally shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow ample time when ordering. If you are in a hurry, please contact us in advance to confirm delivery times. All products are transported via air freight; they are never shipped by sea freight.
○ About Compliance with Japanese Vehicle Inspection (Shaken)
All products we handle are designed and manufactured outside of Japan. Please be aware that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide documents such as strength calculation sheets for these inspections. Therefore, all parts are sold for the purpose of "circuit use, private land, or off-road use," and installation and use are at your own risk.
○ About Warranty
Please inspect the contents 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. We will only provide returns, refunds, or replacement exchanges for items with shipping damage, defective products, or items different from your order if you contact us within 7 days of receipt. Please understand that for products sold through us, warranty-related support will be provided "only through us." We do not provide support through other companies or distributors located within Japan.
