Piano no Mori

Piano no Mori: The Perfect World of Kai (ピアノの森 The perfect world of KAI, lit. "Piano's Forest"?), produced by Gainax's Fukushima branch premiered on April 9 2018 on NHK. The anime series will air 12 episodes. Netflix have announced that they had exclusive streaming rights for the series worldwide, and will simulcast the series in Japan, and release the series globally in Q3 2018.


Piano no Mori is a story that follows Kai Ichinose, a boy who lives in the red light district but escapes at night to play the piano in the forest. Shūhei Amamiya, the grade-school son of a professional pianist, transfers to Moriwaki Elementary, Kai's elementary school. But it doesn't take long before Shuhei is picked on by the class bullies, and gets involved in a dare to play the mysterious piano in the forest, leading to his meeting with Kai, who seems to be the only one capable of getting sound out of the thought-to-be broken piano. Kai's ability earns him the respect of Shuhei and his music teacher, former master pianist Sōsuke Ajino. Both Shuhei and Ajino try to get Kai to take proper piano lessons, but Kai is at first resistant to refining his piano-playing technique. However, after hearing Sosuke play a Chopin piece he just can't seem to play himself, he relents.
