Description

Origins and Succession

Nabeshima Mitsushige (1632-1700) was born in 1632, the eldest son of Nabeshima Tadanao, who was the heir and the fourth son of Nabeshima Katsushige, the first daimyo of Saga domain in Hizen Province. He received a character from the name of the third shogun, Tokugawa Iemitsu, and took the name Mitsushige. Following the death of his grandfather, the first daimyo Katsushige, he succeeded to the headship of the house in 1657 and became the second daimyo of Saga domain.

Domain Governance and the Ban on Junshi

In 1662 Mitsushige banned junshi (ritual suicide to follow one's lord in death) within his domain, doing so ahead of the shogunate's own formal prohibition. The measure is regarded as anticipating a broader shift in early Edo-period samurai society, redirecting the expression of loyalty away from a retainer's death and toward service to the domain itself. In 1683 he also fixed a hierarchy of rank among the three branch domains of Hasunoike, Ogi and Kashima, which had previously stood in something close to equal status, thereby consolidating the domain's system of governance.

As a Man of Culture

Mitsushige was also versed in waka poetry and is said to have received the transmission of the Kokin denju from Sanjōnishi Sanenori, a poet of the Nijō school. Rather than a daimyo of purely martial bent, he had a literary side that gave weight to scholarship, and he is regarded as the figure who laid the groundwork for the encouragement of learning and culture in Saga domain.

Legacy

Mitsushige's rule corresponds to the period in which the foundations of Saga domain laid by his grandfather Katsushige were stabilized and established as institutions. His ban on junshi and his establishment of the branch-domain hierarchy are frequently cited in early-modern daimyo studies as examples of domain administration during the transition from a martial to a civil order.
