The role is Matsu’s first role in an Iwai film since she debuted in film acting in 1998 in Iwai’s April Story.
Iwai wrote, directed, and composed the music for The Case of Hana & Alice, his first-feature length anime film and prequel to his earlier live-action film Hana & Alice.
The film will tackle similar themes about communication as Iwai’s 1995 feature film debut Love Letter.
Director Shunji Iwai revealed on Friday that he is working on a new film titled Last Letter that stars Takako Matsu, Evangelion director Hideaki Anno, Suzu Hirose, Ryunosuke Kamiki, Masaharu Fukuyama, and Nana Mori.
