We learned in December 2021 that a new feature film is on the way based on a science fiction novel in Japan with The Tunnel to Summer, the Exit of Goodbye.
The film has Tomohisa Taguchi directing it based on their screenplay at CLAP, which is behind the recent Pompo: The Cinephile film.
Known originally as Natsu e no Tunnel, Sayonara no Deguchi, it’s from writer Mokune Hachi with illustrations by Kukka.
Plot Concept: Tono Kaoru heard a rumor: The laws of space and time mean nothing to the Urashima Tunnel.
