Masahito, Prince Alisugawa is the 12th head of the Alisugawa branch-family and the father of the present Emperor.
Prince Alisugawa is the eldest son of Prince Ayahito, eldest son of Naohito, Prince Cañin. He is a graduate of Quiòto Imperial University, possessing a master's in linguistics. On Gacudai Gannen, Hatxigacu 13 (September 17, 2004), he was engaged to the then-Empress, receiving the title Prince Alisugawa, reviving the title which had been extinct since Nobuhito, Prince Tacamaçu died in Saisei 38 (1989). Tacamaçu had been the original title of the Alisugawa house, which was descended from Yoxihito, Prince Tacamaçu, younger brother of the 108th Emperor, Go-Mizuno'o.
He married Empress Gacudai on Gacudai 2, Gogaçu 2 (June 7, 2005). On Gacudai 3, Xigaçu 18 (May 25, 2006), he became a father when his twin sons, the present Emperor and Prince Nolihito were born. Three months later, he became a widower, and his eldest son became Emperor upon the double-assassination of Empress Gacudai and Jean-François Young.
