The Former Residence of Shusuke Aoki is the historic home of Shusuke Aoki, a man celebrated as one of the leading Western-style physicians (Ranpo-i) during the late Edo period. Aoki served as the personal physician to the 13th Lord of the Mori Clan, Takachika Mori, and the residence stands as a testament to this significant historical era. The main building is architecturally divided into a formal reception area for guests and a private living space for the family, reflecting the social structures and the bustling atmosphere of a household that once welcomed many students from across the country.
Shusuke Aoki was born in 1803 as the eldest son of a physician in Suo-Oshima. He studied under the renowned doctors Nomi Yu-an and Doan in Mitajiri, and later mastered Western medicine under Tsuboi Nobumichi in Edo. His academic journey even took him to Nagasaki, where he studied the works of influential figures like Philipp Franz von Siebold. In 1838, upon the recommendation of Nomi Doan, he became a clan physician, and by 1848, he earned the trust of the 13th Lord, Mori Takachika, to serve as his personal physician.
Aoki was a pioneer not only in general medicine but also in the implementation of smallpox vaccination. He sent his brother, Kenzo, to Nagasaki to conduct research, which eventually led to the successful introduction of vaccination techniques within the domain. He was also instrumental in the founding of the medical school 'Koseido' and later served as its director. His profound knowledge of Western science significantly influenced the domain's administrative reforms.

Visitors can observe the traditional Japanese architectural style of the main house. The distinct separation between the formal guest rooms and the family living quarters provides a window into the social roles and the historical reality of hosting numerous medical students. The white-plastered walls, traditional roofing, and wooden pillars offer an authentic glimpse into the living spaces of the late Edo period.
