How to work

Welcome to Gonbouyoku self-service page for processing warranty requests and making inquiries. All Gonbouyoku warranties are automatically kept track of in our system, so there is no need to register your product. This page is for you to reach out to us when you have issues with your product or to quickly help resolve any other issue you’re experiencing. We apologize in advance for whatever inconvenience your Gonbouyoku purchase may have caused.

​​

Please note this page is for purchases made through Amazon. For purchases made through Gonbouyoku authorized resellers, please contact them directly.

All products purchased from Gonbouyoku come with a hassle-free warranty. You can find the precise warranty period of your product on the literature inside its box or on this chart. You can also verify the warranty period with our customer service team in the body of your message.

If your product turns out to have a defect during its warranty period, please contact us via the feedback form below and let us know what we can do to help you. It may save you time to first troubleshoot issues by going to our FAQ page or looking at Instruction Manuals before filing a warranty claim.

Thank you in advance for all of the information you provide; we know your time is valuable.

Warranty Information Tips

Order Number: You can find this in the order history of the account the purchase was made through.


Model Number: You can find this in your account's order history, as well as on the packaging or manual of the product. Some products come with the model number printed directly on them. Model numbers help us identify the exact make and model of your product more accurately than a product name would.


Note: Before Gtheos can release a replacement, it may be necessary to return the defective item for quality inspection.
