About JAQAP
Protecting the Value of Authentic Japanese Pianos
in America
JAQAP — the Japanese Association for Quality and Assurance in Pianos — was established to bring a higher standard of trust and transparency to the pre-owned Japanese piano market in the United States.
Inspired by Japan's own rigorous quality certification practices, JAQAP bridges the gap between Japanese craftsmanship and American ownership. Every piano that carries a JAQAP certificate has been inspected, restored, and registered through a structured quality process — giving buyers peace of mind and protecting the instrument's long-term value.
JAQAP certification is available through a select network of authorized piano dealers across the United States each held to the same preparation and inspection standard before any warranty is issued.
Restoration
Prepared by a Master Piano Technician
All pianos bearing a JAQAP certification are subject to a rigorous inspection and restoration protocol performed by master-level technicians trained by Yamaha in Japan and with decades of experience in acoustic piano rebuilding and service.
Each instrument is restored in accordance with the JAQAP Restoration Standard, ensuring consistent performance, precision, and musical integrity. The JAQAP certification upgrades a used Yamaha piano to a like new Yamaha from Japan with warranty and benefits that exceed any new Yamaha.
Certification
Official 10-Year Warranty Certificate
Every JAQAP-certified piano is assigned a unique certificate number that documents the instrument's serial number, brand, model, registration date, and authorized dealer. Your certificate is digitally issued and permanently verifiable by anyone — useful now and when you sell.
Transferability
The Warranty Moves With the Piano
When you sell your JAQAP-certified piano, the remaining warranty transfers to the new owner through our Transfer Ownership process. This isn't just protection for you — it's a documented selling point that adds real resale value to the instrument.

Our Standard
What "JAQAP Certified" Actually Means
The word "certified" should mean something. At JAQAP, it means that every piano bearing our certificate has passed a structured 40-Point Master Technician Inspection before registration is issued.
Our technicians are not generalists. They are experienced master-level piano rebuilders who have trained at Yamaha or have been directly employed by Yamaha. They evaluate and restore each instrument across six major systems before it qualifies for certification.
