Cause → Event → Consequence
During the Genpei War, the Taira clan established a fortified position at Ichi-no-Tani near Suma, exploiting the narrow coastal terrain between mountains and the sea to create a defensible stronghold against the advancing Minamoto forces.
On 20 March 1184, the Minamoto clan, led by Minamoto no Yoshitsune and Minamoto no Noriyori, attacked the Taira fortification at Ichi-no-Tani. Despite the difficult terrain, which constrained troop maneuver, the Minamoto forces overcame the Taira defenses and secured a decisive victory.
The Taira clan suffered a crucial defeat at Ichi-no-Tani, significantly undermining their military strength and territorial control. This loss accelerated their decline during the Genpei War and shifted momentum decisively in favor of the Minamoto clan.
