Idemitsu Mamoru (出光衛; 1938 - 1940)

Idemitsu Mamoru (出光衛; 1938 - 1940) was a cartographer active in Shanghai in the late 1930s and early 1940s. Little is known about his life and training, or even his nationality (he might have been Chinese, in which case his name would be pronounced Chu Guangwei), but he was affiliated with the publisher and bookseller Shiseidō 至誠堂 and may have been the manager of the company's Shanghai branch, located in the heavily Japanese Hongkou neighborhood. His known surviving works include a map of Nanjing and Suzhou published soon after those cities' capture by Japanese forces in the Second Sino-Japanese War.
