Synthesized from 25 Yomimono stories · updated Sep 19

The throughline across these stories is the North American rollout of Cocoon - One Summer of Girlhood, a 63-minute historical drama set in 1945 Okinawa. GKIDS acquired all North American rights and began streaming an English-subtitled trailer on July 16, 2026, with a release date of September 4. The film is based on Machiko Kyo's manga, directed by Yukimitsu Ina in his feature debut, and produced by studio Sasayuri. It follows two schoolgirls, San and Mayu, mobilized through the Himeyuri Student Corps. The anime originally aired in Japan in 2025 on BS-NHK in March and NHK General in August.

GKIDS positioned the release with both Japanese subtitled and English dubbed screenings, and later streamed an English-dubbed trailer on August 18. A review on September 2 called the film a quietly joyful affirmation of life, praising its restrained dialogue and oil-painting backgrounds. The same week, GKIDS apologized for incorrectly timed English subtitles during a screening of The Last Blossom, pulled affected shows from sale, issued refunds, and confirmed cocoon's September 4 opening was unaffected.

Coverage also tracked the film's festival run. The Fantasia International Film Festival in Montreal, running July 16 to August 2, hosted the Canadian premiere of cocoon alongside other anime premieres. Before the wider theatrical rollout, the film had its North American premiere at the JAPAN CUTS event in July. The rollout included both subtitled and dubbed options, and GKIDS said it will announce home entertainment plans and English-language cast details later in the year.
