His life is mostly unknown; it is only assumed that he was the same person as 'Yotsutsuji Wakamiya' (a young Imperial Prince of Yotsutsuji) who was given the territory in 1316, one year before his father, supposedly Imperial Prince Yoshimune, died.
その生涯については謎が多く、父とされる善統親王死去の前年正和5年（1316年）に所領を譲られた「四辻若宮」と同一人物であったと推定できるのみである。
