Kakuma Gorge (Nagano Prefecture) Complete Guide | Thorough Explanation of Sarutobi Sasuke’s Training Ground and Spectacular Hidden Gem
Kakuma Gorge is located in Sanada Town, Ueda City, Nagano Prefecture, and is a large gorge spanning approximately 4 kilometers in length that spreads across the foothills of Mount Eboshi. Also known as “Shinano Yabakei,” this gorge is recognized as one of the prefecture’s most scenic spots and is famous as the legendary training ground of Sarutobi Sasuke, a ninja and one of the Ten Braves of Sanada. The spectacular scenery woven together by steep cliffs, clear streams, and natural beauty that changes with each season continues to captivate visitors.
Overview and History of Kakuma Gorge
Kakuma Gorge is located on the northern foothills of Mount Eboshi, at the municipal boundary with Tomi City, and was formed by the erosion of the Kakuma River. Andesite and tuffaceous breccia created by volcanic activity have been eroded by wind and rain over many years, creating the dynamic landscape we see today.
Numerous unusual rock formations and scenic spots dot the gorge, named after their shapes, such as “Oni Castle,” “Demon’s Gate,” “Tengu’s Railing,” and “Lion’s Cage.” Since ancient times, the valley has been feared as a place where demons dwell and has been passed down in local folklore with reverence.
The Training Legend of Sarutobi Sasuke
Kakuma Gorge is known as the place where Sarutobi Sasuke, a ninja and one of the Ten Braves of Sanada, honed his skills. It is said that he underwent rigorous training between the steep dual rock walls and perfected his acrobatic climbing and jumping techniques.
Within the gorge, there is a place called “Sarutobi Stone,” where a legend remains that Sasuke practiced by jumping over this rock. Visiting the site in person allows one to imagine the ninja’s harsh training from its ruggedness, making it a tourist attraction filled with historical romance.
Main Attractions of Kakuma Gorge
Oni Castle
“Oni Castle,” towering on the left bank of the Kakuma River, is a distinctive rock formation representing Kakuma Gorge. The harder portions of the tuffaceous breccia layer have withstood erosion and remain as a towering rock peak. Its overwhelming presence is truly as imposing as a castle where demons would dwell, and it is the biggest attraction that catches the eyes of visitors to the gorge.
It is also geologically fascinating, serving as a valuable natural heritage that tells the story of volcanic activity and erosion.
Demon’s Gate
“Demon’s Gate” is a scenic spot characterized by giant rocks standing in a gate-like formation. Passing through the space between these rocks creates a mysterious atmosphere as if entering a gateway to another world. The contrast between the clear stream flowing between the steep rock walls is beautiful and makes for a popular photography spot.
Tengu’s Railing
“Tengu’s Railing” is a group of unusual rocks that appear to be lined up like a railing. From its unique shape, it was named after the railing of a bridge used by tengu (mountain goblins). The sculptural beauty created by nature leaves a deep impression on all who visit.
Iwaya Kannon
At the base of the steep cliff of Kakuma Gorge, an Iwaya Kannon (Kannon statue in a rock cave) is carved. The stone steps leading to this Kannon consist of 222 steps, allowing visitors to undergo an experience like ascetic training as they climb the steep stairs. The view from Iwaya Kannon is also wonderful, offering a vantage point from which to view the gorge’s spectacular scenery in its entirety.
It also has a long history as a place of worship and remains a sacred site cherished by local people.
