Kousaka’s Okko’s Inn anime film opened in Japan in September 2018, and is based on writer Hiroko Reijō and artist Asami’s juvenile literature series.
The film tells a story not told in either the original book series or April 2018 television anime series — specifically, a story about Okko and her parents.
DLE also partnered with Chinese film company Shanghai Griffin Film Corporation in 2016 to produce new creative projects in both Japan’s and China’s animation industries.
DLE and Madhouse animated the film along with the television anime, but Kousaka (A-Girl, Nasu: Summer in Andalusia) directed the film instead of the television anime’s directors.
