Film opens in theaters on December 13, launches streaming on December 18

The official website for the In This Corner (and Other Corners) of the World [ Kono Sekai no (Sara ni Ikutsumono) Katasumi ni ] anime film revealed on Thursday that the new Katasumi-tachi to Ikiru Kantoku Katabuchi Sunao documentary film about director Sunao Katabuchi will open in theaters in Japan on December 13. The 95-minute film will also begin streaming on iTunes, Amazon Prime Video, Google Play, and Hikari TV on December 18.

The documentary will show production of In This Corner (and Other Corners) of the World [ Kono Sekai no (Sara ni Ikutsumono) Katasumi ni ], the extended version of the anime film adaptation of Fumiyo Kouno's In This Corner of the World (Kono Sekai no Katasumi ni) manga. The documentary will also follow Katabuchi as he does research for the film.

The extended version of the film will open in Japan on December 20.

Kana Hanazawa is playing the new character Teru, a woman that Suzu meets in the red-light district.

The new version was originally slated to screen in Japan in December 2018, but was delayed to this year. The staff stated last October that the production needed a few more months than the staff originally projected, and in order to live up to fans' expectations of the film's quality, the production committee decided to delay the film.

The extended version will feature about 30 more minutes of footage. The film's director Sunao Katabuchi (Black Lagoon, Mai Mai Miracle) planned the title with Kouno's approval. The concept behind the new version is to give the perspective of "several more lives" in addition to Suzu's, so it has a new title to reflect the new theme. The new work will adapt more scenes from the manga.

The new scenes include Suzu crossing paths with Rin in the fall of 1944 and the winter and spring of 1945. Another new segment will focus on the Makurazaki Typhoon of September 1945, while Suzu is worried for her younger sister Sumi.

Non is again voicing Suzu. kotringo is returning to compose and perform a new song "Kanashikute Yarikirenai" (It's Sad and I Can't Bear It).

Shout! Factory and Funimation Films screened the original film in the United States and Canada in August 2017.
