Ikura Gorge

Ikura Gorge is a limestone canyon in Niimi formed by the Takahashi River cutting through the karst terrain of the Atetsu Plateau. The vertical stone walls create a deep valley with a raw, sculptural appearance shaped by millions of years of water flow.

The gorge developed over millions of years as the Takahashi River gradually eroded the limestone bedrock, creating the deep valley we see today. This ongoing geological process also shaped the extensive cave system that lies beneath the surface.

The gorge draws visitors during autumn when maple leaves turn brilliant red and orange, creating a striking display against the gray limestone walls. This seasonal transformation has made it a favored spot for nature photographers and leaf-watching trips.

The site is easily reached from Ikura Station with a short walk to the main area. Parking is available nearby, making access convenient for visitors arriving by car.

Beneath the visible canyon lies a cave system containing multiple waterfalls that flow through the limestone formations. One waterfall drops through a natural opening in the ceiling, creating a dramatic underground scene that few visitors explore.
