Ikura Gorge, Limestone canyon in Niimi, Japan.
The gorge features vertical limestone cliffs reaching 240 meters in height, carved by the Takahashi River through the Atetsu Plateau karst formation.
The natural formation developed over millions of years through water erosion of limestone deposits, creating both the gorge and the 1,200-meter-long Ikura Cave system.
The gorge becomes a regional celebration site during autumn when the gray limestone walls contrast with red and orange maple leaves.
Visitors can access the site through JR Ikura Station with a 15-minute walk, while the parking area accommodates 250 cars and 20 buses.
Inside Ikura Cave, three waterfalls cascade through the limestone formations, with one falling 50 meters through a natural skylight opening.
