Shoun Falls

was a waterfall located at Mount Furai.

History
Akitoki Hōjō was seeking Kaede on how to purify the ken blade of the Naginata of Kenkon. She instructed Akitoki to follow the Shoun Falls upwards toward the Furai shrine where he could purify the blade. Inuyasha's group accompanied him.

When Akitoki and Kagome were separated from the rest of the group after an attack by Hoshiyomi's demon ninjas, they were approached by Genbu's puppets. Kagome discovered the trap and destroyed them, but was kidnapped by the demons, who followed the river and the waterfall on Mount Furai. The demon ninjas were sent by Hoshiyomi to fight around the waterfall at the foot of the mountain. Each ninja would fight against each member of the Inuyasha team: Genbu against Inuyasha, Byakko against Miroku, Seiryū against Sango, and Akitoki against Suzaku. Hoshiyomi finished the ceremony to once again join the ken and kon blades, and form the Kenkon halberd. Akitoki was dragged by the waterfall, and Shippō transformed to rescue him, but is attacked by the original form of Suzaku and falls to the edge of the mountain again. Inuyasha use the Blades of Blood to Byakko as Miroku managed to absorb three demon ninjas into his Wind Tunnel. Suzaku tried to escape flying over the waterfall, but was still sucked in. After that, Akitoki apologized to Inuyasha and the gang he has let them down and saw the symbol of the pentagram and heads to the shrine.
