Masahito's eldest son was Imperial Prince Kazuhito (和仁親王, Kazuhito-shinnō, 1572–1617), who acceded to the Chrysanthemum Throne on the abdication of Emperor Ōgimachi. Kazuhito would become known as Emperor Go-Yōzei.[1]

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.

  • 21–25 August 1598 (Keichō 3, 20-24th day of the 7th month): Buddhist rituals were performed in the Seriyoden of the Imperial Palace to celebrate the 13th anniversary of the death of the emperor's father.[2]

The actual site of Prince Masahito's grave is known. This posthumously-elevated emperor is traditionally venerated at a memorial Shinto shrine (misasagi) at Kyoto.

The Imperial Household Agency designates this location as Yōkōin's mausoleum. It is formally named Tsuki no wa no misasagi at Sennyū-ji.[1]
