Piano no Mori is the story of two boys from different upbringings brought together through a shared love for the piano and dream to become the best pianist in Japan. Set in a rural town, Shuhei Amamiya is a transfer student from Tokyo whose father is a famous pianist and Kai Ichinose is poor and fatherless, but raised by his loving mother Reiko who is a prostitute and gave birth to him at the age of 15. While Shuhei has a lesson room with a grand piano in his house, Kai plays a broken piano in the forest which mysteriously only works for him.


Piano no Mori began as a Japanese manga series written and illustrated by Makoto Isshiki that was serialized by Kodansha from 1998 to 2015, first in Young Magazine Uppers from 1998 to 2004 and then in Weekly Morning from 2004. The series ended after 26 collected volumes. The manga is published in English by Kodansha Comics.

In 2007, the series was adapted into an animated feature film produced by Madhouse and directed by Masayuki Kojima with performances by renowned pianist Vladimir Ashkenazy.

The first season of the TV anime adaptation was produced by Gaina with Gaku Nakatani and Ryutaro Suzuki directing, Aki Itami and Mika Abe writing the scripts, Sumie Kinoshita handling the character designs, and Harumi Fuki composing the music. The first season aired from April to July 2018 and lasted 12 episodes. The second season of the anime, also being produced by Gaina, sees Hiroyuki Yamada taking over as director with many of the same staff from season 1 returning. The anime will premiere on Jan. 29, 2019. Netflix has acquired exclusive streaming rights for the series worldwide.
