From when the Empress Jingo-kogo led an invasion of Korea while pregnant with the future Emperor Ojin, tales of female Japanese warriors have emerged from Japan’s rich history. Using material that has never been translated into English before, this book presents the story of Japan’s female warriors for the first time, revealing the role of the women of the samurai class in all their many manifestations, investigating their weapons, equipment, roles, training and belief systems. Crucially, as well as describing the women who were warriors in their own right, like Hauri Tsuruhime and the women of Aizu, this book also looks at occasions when women became the power behind the throne, ruling and warring through the men around them.
