Because he was not included in the princes who participated in the Yoshino Pact in 679, and the rank of 'joko ichi' (the first rank of joi yoshina, four rank of joi, which corresponds to Shoshiinoge, Senior Fourth Rank, Lower Grade in ranks for Shoo and shoshin, vassal of Taiho Ritsuryo, Taiho Code) appears in "Shinsen Shojiroku" (Newly Compiled Register of Clan Names and Titles of Nobility), it is likely that he had died right before the Taiho Ritsuryo (Taiho Code) was established, at the age of around 30.
679年（天武8年）の吉野の盟約に参加した諸皇子に名を連ねていないこと、また『新撰姓氏録』に「浄広壱」とあることから、大宝律令成立直前に30歳前後で早世したと推定される。
