This documentary film was produced by the Japanese Government-General of Joseon to introduce Joseon's ondol (a traditional Korean sub-floor heating system) and winter culture to Japan. The film takes a close look at the heating mechanism of the ondol, the installation process, how Koreans get through the winter in a house equipped with ondol, children's various winter games, and a visit to a kitchen, where 'gourd dippers' (unfamiliar to Japanese people) are shown and Korean names for things, such as ‘food blade' for a kitchen knife, are described. This film’s tone resembles an anthropological report. The ending is also impressive. The film beautifully utilizes the sound of fulling cloth resonating quietly on a winter night. Collected in 2020, and transferred in 4K resolution.
