Oda Nobuoki
Nobuoki was a younger brother of Oda Nobunaga and came to hold Ogie castle in Ise province. In 1570 his castle was surrounded by rioting ikko-ikki from Ise's Nagashima area. Nobunaga was occupied with the Asai and Asakura families at the time and could send no assistance. As a result the castle fell and Nobuoki, after climbing to upper level of his keep, committed suicide.
