 Upon graduation from university, Hiratsuka entered the Narumi Women's English School where, in 1911, she founded Japan's first all-women literary magazine, "Seitō" (, literally Bluestocking).She began the first issue with the words, “In the beginning, woman was the sun” () – a reference to the Shinto goddess Amaterasu, and to the spiritual independence which women had lost.Adopting the pen name “Raichō” (“Thunderbird”), she began to call for a women’s spiritual revolution, and within its first few years the journal’s focus shifted from literature to women’s issues, including candid discussion of female sexuality, chastity and abortion.
