The Headship at Seven: The Day Tachibana Dōsetsu Passed the House to His Daughter

In 1575 (Tenshō 3), Bungo Province. Tachibana Dōsetsu named his seven-year-old daughter Ginchiyo as the successor of the Tachibana headship.

As a Sengoku-period warrior-house inheritance, transfer to a woman was extraordinary.

Dōsetsu was a senior retainer of Ōtomo Sōrin, and made his name as a warrior of Bungo Province.

Ginchiyo was Dōsetsu's sole daughter; there were no other sons. Dōsetsu's decision was the choice of passing the house to his actual daughter rather than taking an adopted heir.

In the warrior custom of the time, adoption succession was standard, and Dōsetsu's decision was exceptional.

Ginchiyo was set up as the castellan of Tachibana-yama. Actual rule was supported by Dōsetsu and the senior retainers, but the headship was inherited in Ginchiyo's name.

This formal headship was not mere nominalism; it became the foundation for the legitimacy of the later succession of Muneshige (Ginchiyo's husband) to the Tachibana house.

In 1581, Dōsetsu took the eldest son of Takahashi Jōun — Muneshige — as Ginchiyo's husband.

Muneshige entered the Tachibana as adopted son, and as Ginchiyo's husband became the substantive leader of the house.

The headship, however, remained with Ginchiyo.

Dōsetsu died in 1585. The name of Ginchiyo, who had inherited the headship at seven, lived on in the Tachibana house as the form of Dōsetsu's will.

When Muneshige was later stripped of Yanagawa domain after Sekigahara, and when he was pardoned by the Tokugawa and restored to Yanagawa in the early Edo period, the origin of the Tachibana house lay in the inheritance from Dōsetsu to Ginchiyo.
