Kakegawa-birthplace of the Yamaha piano
I visited Hamamatsu Museum of Musical Instruments (http://www.tripadvisor.com/Attraction_Review-g303148-d1016725-Reviews-Hamamatsu_Museum_of_Musical_Instruments-Hamamatsu_Shizuoka_Prefecture_Chubu.html#) and Yamaha Grand Piano factory in Hamamatsu. Both were very much interesting for me.
In Hamamatsu Museum of Musical Instruments, I could see not only western musical instruments like various unique violins, but also many Asian very historic and deluxe musical instruments such as gamelan. They were so much beautiful!
At Yamaha Grand Piano factory in Hamamatsu, I could see some grand piano manufacture processes. However, from the beginning of early 2011, Kakegawa will be the center of Yamaha piano-making operation. You can hear some interviews of craftsmen, and see piano-making processes and a lot of related information in this website.
