Forest of Piano season 1 is available in: Japanese [Original] on Netflix Japan
A tranquil tale about two boys from very different upbringings. On one hand you have Kai, born as the son of a prostitute, who's been playing the abandoned piano in the forest near his home ever since he was young. And on the other you have Syuhei, practically breast-fed by the piano as the son of a family of prestigious pianists. Yet it is their common bond with the piano that eventually intertwines their paths in life.
Kai grows up playing an old piano discarded in the woods; Shuhei's father is a famous pianist. Their chance meeting transforms their lives and music.
