Nagao Sōjō 長尾藻城, early-twentieth-century Japanese physician-editor active in the Meiji-Taishō transition (fl. 1900s–1930s by internal evidence), principal compiler of KR3eq038 Xiānzhé yīhuà jí 先哲醫話集 — a one-juǎn anthology of approximately one hundred and thirty clinical maxims drawn from the entire range of Edo-period Japanese kohōha and gosei-ha medical literature. The compilation is modelled on Asada Sōhaku’s KR3ep002 Xiānzhé yīhuà 先哲醫話 (1879) but with a substantially broader source-base extending to Meiji-era authors. Not in CBDB (Japanese figure); no further independent biographical documentation located in available references.
