Hiratsuka Raicho was born in 1886 in Tokyo, the daughter of a well-to-do senior government official who had studied in Europe; her birth name was Haruko. She graduated from Japan Women’s College (developing a lifelong interest in Zen meditation while a student) in 1906. The next few years were spent studying English and Japanese literature at various schools (including the Eigakujuku founded by Tsuda Umeko), where she studied writing with Ikuta Choko and Morita Sohei. In 1908 Haruko and Morita plunged into a rapidly developing love affair, culminating in an attempt at a love-suicide which it turned out neither of them could bring themselves to go through with. This created an enormous scandal (causing Haruko’s father to lose his job and estranging them until her children were born years later), especially when Morita wrote a novel about it.

In 1911, upon Ikuta’s suggestion that she found a literary magazine run entirely by women, she consulted with her sister’s friend Yasumori Yoshiko and formed an initial editorial board of herself, Yoshiko, Nakano Hatsuko, Kiuchi Teiko, and Mozume Kazuko. The funding for their first issue came from what would have been Haruko’s dowry, handed over by her resigned but supportive mother Tsuya. The magazine was christened Seito [Bluestocking], and Naganuma Chieko drew the illustration for the cover of the inaugural issue, which included a poem by Yosano Akiko and Haruko’s own essay on the theme of “In the beginning, woman was the Sun,” which became a classic of Japanese feminist literature on the spot. The essay called for women’s genius to be released from the strictures of a patriarchal society. It was at this time that she began using the penname Raicho, “thunderbird” or rock ptarmigan.

Other supporters included Hasegawa Shigure, Okada Yachiyo, Mori Shige, and Koganei Kimiko; contributors and assistants included Tamura Toshiko, Nogami Yaeko, Mizuno Senko, Otake Kokichi, Senuma Kayo, Kamichika Ichiko, Ito Noe, Mikajima Yoshiko, and Okamoto Kanoko. Raicho was the moving force, organizing an edition dedicated to discussion of Ibsen’s Nora and her ramifications as well as lecture series and other events. The Bluestocking women became notorious not only for their literary and activist work but also for the “Five-Colored Alcohol Incident” (in which Kokichi went out to a fashionable bar and drank fancy cocktails) and for their in-person observation of the Yoshiwara red-light district (where Raicho chatted with a woman who had attended the same elementary school), identifying them as “decadents,” modern feminists, New Women, distinct from traditional good girls. This era apparently saw a record number of “Noras,” daughters and young wives leaving home with no warning. Raicho took up the gauntlet without hesitation, adding translations of texts by Ellen Key and Emma Goldman to her magazine. Articles by the activist Fukuda Hideko and by Raicho herself earned publication bans from the government.

Raicho spent 1911 and 1912 in a relationship with the “boyish” Kokichi, who liked to affect masculine dress (there is relatively little to be found about this in histories of Raicho, especially in Japanese). In 1914 she moved in with the artist Okumura Hiroshi, nicknamed the “little swallow” because he was (gasp, shock, horror) three years younger than she was. She continued to insist on a common-law marriage until 1941, when wartime asperities made it more convenient to marry officially. In her eyes the relationship was a part of her refusal to engage in the “good wife, wise mother” style of marriage which restricted women’s freedom, but many of the older women in her vicinity, Akiko included, saw it as a feckless young artist leeching off the older and (somewhat) more together Raicho.

Distracted by pregnancy and Okumura’s illness, Raicho passed on editorship of Bluestocking to Ito Noe in 1915; the magazine lasted another year and a bit. Raicho herself later worked as a critic, raised two children (Akemi, born in 1915, and Atsufumi in 1917, both on Raicho’s family register rather than Okumura’s), and engaged in debates on motherhood with Akiko, Yamakawa Kikue, and Yamada Waka. In 1920, she founded the New Women’s Association along with Ichikawa Fusae and Oku Mumeo, fighting for women’s suffrage and greater support for mothers, specifically for an amendment to Article 5 of the Peace Police Law, which prohibited women’s political participation, and a law restricting marriage for men with venereal disease. The former demand was realized two years later (although the latter never came about). With the support of well-known male writers including Sakai Toshihiko, Mori Ogai, and Arishima Takeo, the new Association thrived and Raicho resorted to Western dress to save time amid lecture tours and articles. Three years later she cut her hair (or rather had Okumura cut it for her), becoming the image of the short-bobbed Modern Girl (although her original purpose was to cure her chronic headaches).

Raicho devoted herself after the war to working for world peace through women’s organizations, including opposition to the Vietnam War. She remained the main household breadwinner, albeit with financial support from her birth family. Okumura died in 1964, and Raicho followed him in 1971 at the age of eighty-five.
