Ōtsuka Usaburo0 (大塚宇三郎)
Ōtsuka Usaburō (大塚宇三郎 ; fl. c. 1882 - 1909), also sometimes using the courtesy name Shisei (子成), was an Osaka-based editor, printer, and publisher of books and maps. He operated in Minami ward of Osaka and worked within a close-knit local publishing network, frequently partnering with research organizations such as the Chiri Kenkyūkai (地理研究会, Geographical Research Society) and printer Sonoda Tōzaburō (園田藤三郎). He also collaborated extensively with the prominent Osaka publishing firm Tanaka Taemon / Tanaka Sōeidō (田中太右衛門 / 田中宋栄堂), which operated just a few doors away on Andōjibashi-dōri in 4-chōme of Minami Ward. Capitalizing on the Meiji public's intense demand for geographic information driven by Japan's overseas military expansion, Ōtsuka produced numerous maps of Taiwan, Korea, and continental East Asia. Alongside his overseas maps, Ōtsuka produced pocket maps catering to travelers navigating Japan's rapidly expanding domestic rail and steamship networks. Beyond cartography, Ōtsuka compiled and published a wide variety of practical Meiji reference books, including Chinese character dictionaries, legal commentaries, and letter-writing manuals.
