Background
Prince Masahito died before his father.
誠仁親王
Prince Masahito died before his father.
Masahito"s eldest son was Imperial Prince Kazuhito (和仁親王, Kazuhito-shinnō, 1572-1617), who acceded to the Chrysanthemum Throne on the death of Emperor Ōgimachi. Kazuhito would become known as Emperor Go-Yōzei. Later, Go-Yōzei elevated the rank of his father, even though his father"s untimely death made this impossible in life.
In this manner, Go-Yōzei himself could enjoy the polite fiction of being the son of an emperor.
The actual site of Prince Masahito"s grave is known. The Imperial Household Agency designates this location as Yōkwōin"s mausoleum.
lieutenant is formally named Tsukinowa no misasagi at Sennyū-ji.
