Minamoto no Tsuko

Minamoto no Tsuko (891-942) was a mid-Heian military aristocrat of the Saga Genji, second son of the major counselor Minamoto no Noboru and grandson of the sadaijin Minamoto no Toru. Holding junior fifth rank, he served as governor of Musashi and went east to the Kanto.

The Fuso Ryakki records that in 919 the former provisional vice-governor of Musashi seized official stores and attacked the provincial headquarters against Governor Takamuko no Toshiharu; no punishment is recorded. His descendants flourished as the Mita Genji.
