The Chigo Deeps (Chigo ga fuchi) of the play title Keisei chigogafuchi (A courtesan and deep water at Chigo: けいせい稚児淵) was located off the island of Enoshima. It was there in the twelfth century that a young temple page (chigo) named Shiragikumaru committed suicide rather than choose between two priests who vied for his love. Elements of this ancient tale were also adapted for the present play about the legendary sixteenth-century outlaw Ishikawa Goemon. (The various and very popular Gonpachi Komurasaki mono (plays about Gonpachi and Komurasaki: 権八小紫物) were based on actual tales involving unrelated historical figures. The samurai Shirai Gonpachi (白井権八) was guilty of murder and robbery, and was executed in 1679. The second figure was the legendary otokodate (lit., standing man, i.e., chivalrous commoner: 男伊達 or 男作) Banzuin Chôbei (幡随長兵衛), ca. 1622-1657, said to have been killed by Mizuno Jûrozaemon, a leader of hatamoto-yakko (bannermen footsoldiers: 旗本奴). Banzuin was also the subject of puppet and kabuki plays called Banzuin Chôbei mono (plays about Banzuin Chôbei: 番随長兵衛物).
