Dai Nippon Butoku Kai
In his latter years, Prince Komatsu was a patron of the Japanese Red Cross Society and the "Dai Nippon Butoku Kai", along with other charity institutions. As Prince Komatsu died without heirs, the title of Komatsu-no-miya reverted to his younger brother, Prince Higashifushimi Yorihito. However, to preserve the Komatsu family name, in 1910 the fourth son of Prince Kitashirakawa Yoshihisa was renamed Teruhisa Komatsu, with the peerage title of marquis ("koshaku").
