Two weeks ago while on holiday in Japan from Australia we were in Kanazawa. In the basement concourse of the station there were two beautiful Yamaha pianos placed there for anyone to play. They were there available to play from early in the morning until late at night. They were in beautiful condition and the sound was so good. Does anyone know anything about them? How did they get there? How long have they been there? Is there any protection for them?
