Her birth name was Ichi Kamichika and her pen name was Ei, Yo, or Ou Sakaki(榊 纓).

After World War II, Kamichika served in the Japanese House of Representatives as a member of the Japan Socialist Party.

Kamichika grew up in relative poverty due to the death of her father and eldest brother at a young age.

She and Suzuki later created the Fujin Bungei in 1934, a literary journal that featured women writers and questioned Japan's increasing nationalism just before World War II broke out.

She was famously quoted stating that "we must punish the estimated five hundred thousand prostitutes to protect the lifestyle of forty million housewives.
