The work is written in the classic form of Fukushiki Mugen-Noh, which consists of three parts: a first part in which travelling monks happen to see fishermen, the Kyogen part (a farce played during a Noh play cycle) in which the fishermen have disappeared and the monks ask a local villager about this mystery, and a last part in which the main character Yoshitsune appears as a ghost.
作品は典型的な複式夢幻能の形式をとり、旅の僧が漁師にであう前段、漁師がきえた後、僧がその不思議を土地の住人にたずねる狂言部分、主人公義経が生前の姿であらわれる後段の三部構成をとる。
