Kwantung Leased Territory
The airline had a "hub" in Hsinking and was linked by regular flight routes from Harbin, Shamussi (Kiamusze), Kirin, Mukden, Antung, Chinchow, Chengde, Tsitsihar, Hailar, and the Kwantung Leased Territory and Korea areas, for connections with Imperial Japanese Airways (Dai Nippon Koku KK) to Japan itself or foreign routes. A long distance route between Hsinking and Berlin was also pioneered in 1938.
