The siege of Fukuryūji took place in 1183, and was a battle of the Genpei War, the great 12th-century Japanese civil war between the Taira clan and the Minamoto clan. Fukuryūji (福隆寺) was a fortress belonging to Seno Kaneyasu, a Taira partisan. Imai Kanehira led his men across muddy ricefields, under heavy archer fire, to take the fortress. The attackers were victorious, and Kaneyasu was killed.^[1]
