山内千代（見性院）
Wife of the Lord of Tosa Domain
Description
Life
Kenshō-in (also known as Chiyo) is traditionally said to have been born in 1557 in Ōmi Province. Her origins remain uncertain: one theory identifies her as the daughter of Wakamiya Tomooki, a retainer of the Azai clan, while another names her as the daughter of Endō Morikazu, a local lord of Mino. Even her given name is disputed, recorded variously as "Chiyo" or "Matsu." She is said to have caught the eye of Yamauchi Kazutoyo while teaching sewing at the residence of the Nagano family in Ōmi, where Kazutoyo's mother had taken refuge.
The Legend of the Wife's Hidden Merit
The best-known story about Kenshō-in tells how she used her dowry money to purchase a fine horse, the "Kagami-gurige." When Oda Nobunaga held a military review in Kyoto in 1582, the horse reportedly caught his eye, leading to greater renown and reward for Kazutoyo. Modern scholarship, however, suggests the tale took shape during the Edo period and questions its historical accuracy. Other anecdotes credit her with turning a measuring box upside-down to serve as a cutting board, and selling her own hair to pay for laborers' meals during a castle construction project.
Family
Kenshō-in and Kazutoyo had one daughter, Yone, who died young in the Tenshō earthquake of 1585. The couple later took in an abandoned child, who was raised and eventually became the monk Shōnan Sōge at Myōshin-ji temple. Kazutoyo's nephew Tadayoshi, son of his younger brother Yasutoyo, was adopted as heir to the Yamauchi house.
Later Years
After Kazutoyo's death in 1605, Kenshō-in left Tosa and settled in Kyoto near the residence of Kōdai-in (Nene), receiving a stipend of 1,000 koku from the Tokugawa shogunate. She reportedly worked to maintain ties between the Toyotomi and Tokugawa houses. In her later years she is said to have devoted herself to reading the Kokin Wakashū and Tsurezuregusa and practiced calligraphy. She died on December 31, 1617, attended by Shōnan Sōge, at the age of 61.
Later Reputation
The legend of Kenshō-in's devoted support of her husband became, especially from the modern era onward, a widely cited model of the ideal wife taught in schools. As a representative example of a wife who helped her husband rise to prominence, she has repeatedly appeared in later storytelling, fiction, and television dramas.
