While teaching at a girls school in Tokyo, she assisted her husband in his
literary magazine,
Chōon, by contributing
tanka verses and helping in its overall administration. On Ota's death in 1955, she took over responsibility for the magazine with her son, Ota Seikyu. She published numerous anthologies of her poetry during her lifetime, including
Fuji no Mi ("Wisteria Beans"),
Asa Tsuki ("Morning Moon"),
Asa Ginu ("Linen Silk"), and
Kamakura Zakki ("Kamakura Miscellany"). She also published some instructional guides to the writing of poetry, including
Waka dokuhon ("A Guide to Waka Verse"),
Dentō to Gendai Waka ("Tradition and Modern Waka"). Mitsuko and her husband Mizuho Ota began to live in
Kamakura,
Kanagawa Prefecture from 1934, calling their retreat "Yo-yo Sanso." What began as a quiet getaway became their permanent home from 1939. Shiga continued to live there after her husband's death, and died in 1976. Her grave is at the temple of
Tōkei-ji in Kamakura, which also has a large stone monument inscribed with one of her verses. ==See also==
