An industrial town Hamamatsu
Hamamatsu is the middle of Tokyo and Osaka. If you would arrive at Hamamatsu station,you could find some new cars and musical instruments.So Hamamatsu is the big city of being some automobile companys ,Honda,Suzuki,and instrument company's,Yamaha,Kawai.
I don't think tourists would visit in Hamamatsu for sightseeing,however if you are interested in Japanese manufacturers, it is better to check in this city.
