Jinbo Yukiko

Jinbo Yukiko was born in 1845 (Kōka 2), the daughter of Inoue Kyūgu, a retainer and military scholar of the Aizu domain. She married Jinbo Shuri, son of the Aizu chief retainer (karō) Jinbo Toshitaka, a man reputed to have had unusually broad knowledge of international affairs and to have been involved in organizing the Byakkotai (White Tiger Corps). In 1868 (Keiō 4), however, following the Battle of Toba-Fushimi, Shuri was held responsible for having advised submission to the new imperial government; facing backlash within the domain, he was made to commit ritual suicide (seppuku) in Aizu. Yukiko, still in her early twenties, was widowed at that point.

Soon after her husband's death, the Boshin War entered its decisive phase in the region: in the eighth month of 1868 (Keiō 4), the imperial army closed in on Aizuwakamatsu Castle. The Aizu domain effectively fought a total war involving the families of its retainers, and many women are said to have taken part in fighting both inside and outside the castle, or in supporting roles behind the lines. Yukiko has long been said to have joined the all-female unit organized by Nakano Takeko and others — variously called the Jōshitai or Fujotai — and to have taken part in fighting outside the castle walls. Later research, however, has cast doubt on parts of this account. An investigation by Yamakawa Kenjirō, an Aizu-born figure who later became a physicist and served as president of Tokyo Imperial University, could not confirm that Yukiko actually joined the main body of the women's unit; instead, it suggests she acted alone and ultimately died near Namida-bashi ("Tears Bridge"). Coming from a fellow native of Aizu, this account carries a certain weight, though it too is not based on direct first-hand testimony. A separate account, said to have been related after the war by the Tosa domain retainer Yoshimatsu Hayanosuke, describes an even more harrowing fate: that Yukiko was captured by soldiers of the Ōgaki domain, subjected to abuse, and afterward given a short dagger with which she took her own life.

Given these conflicting accounts, it cannot be stated with certainty whether Yukiko actually took part in organized combat as a member of the women's corps, nor exactly where or how she ultimately died — multiple, mutually inconsistent versions of her final days coexist in the historical record, and the surviving source material is too thin to settle the question definitively. With that important caveat acknowledged, she continues to be remembered as one of the figures who symbolize the tragedy of the Boshin War in Aizu, in which women who had already lost their husbands one after another were nonetheless drawn inexorably into a fight for the survival of their domain.
