A pictorial subject depicting scenes from the Battle at Ichinotani, a decisive confrontation in the Genpei war Genpei kassen 源平合戦. According to Heike monogatari 平家物語 (The Tale of The Heike), and Genpei seisuiki 源平盛衰記 (The Rise and Fall of The Genji and The Heike), in the second month of 1184, Minamoto no *Yoshitsune 源義経 (1159-89) led a surprise attack against the Taira 平 fort at Ichinotani (present-day Suma 須磨) in Hyōgo Prefecture. While half of the Genji 源氏 (Minamoto) forces attacked from the west, Yoshitsune led the other half down the steep slope of Hiyodorigoe 鵯越 pass directly behind the Heike (Taira) encampment, driving those unsuspecting warriors into the sea. During the battle on the beach, the older Genji warrior Kumagai Naozane 熊谷直実 (1141-1208) captured the courtly youth Taira no Atsumori 平敦盛 (1169-84), but was so impressed by the boy's beauty and grace that he could only bring himself to kill Atsumori to prevent the youth's death at the hands of less appreciative men. The incident, reported in The Tale of The Heike, formed the basis of the *noh 能 play Atsumori 敦盛, as well as jōruri 浄瑠璃 and *kabuki 歌舞伎 versions. Since the 16th century the battle at Ichinotani was frequently depicted on folding screens *byōbu 屏風, such as the one in Chishakuin 智積院, Kyoto. As individual depictions, the stories of Yoshitsune's surprise attack or the confrontation of Kumagai and Atsumori were often illustrated, especially in *ukiyo-e 浮世絵 prints.
