Hoshina Masaari
Viscount Hoshina Masaari (保科 正益) (March 22, 1833 – January 23, 1888) was a Japanese daimyō of the late Edo period who was the last ruler of the Iino Domain (Kazusa Province; 20,000 koku). Though lord of a minor domain, his family was a branch of the Matsudaira of Aizu, whose founder Hoshina Masayuki was the older brother of the Iino founder, Hoshina Masasada. Masaari was born in Edo to the 9th Iino lord, Hoshina Masamoto. Masaari was the younger brother of Matsudaira Teru. As he was initially weak, his father did not notify the shogunate of his birth.
