Prince Sanehito
son of emperor Ōgimachi
Prince Masahito (誠仁親王, Masahito-shinnō; 16 May 1552 – 7 September 1586), also known as Prince Sanehito and posthumously named Yōkōin daijō-tennō, was the eldest son of Emperor Ōgimachi. He predeceased 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 abdication 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.
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.
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.

Why this record matters
The phrase “son of emperor Ōgimachi” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jul 6, 2026. The linked authority identifier is Q837231. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1552, 1586, 1572 and 1617.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
