Document 72 Hours - Season 5 Episode 12

In Miyazaki Prefecture, a brightly colored piano stands in a street side plaza. This "street piano" can be played freely by anyone at any time. Players range from an elderly woman playing a children's song, to young students performing a TV drama theme song. One man even taught himself to play by visiting the piano every day, and his performance is now applauded by those who gather to listen. The piano was placed in the plaza 4 years ago to liven up the city, and has quietly become a popular spot. What thoughts do people weave into the melodies they play on this street piano?
