This article comprehensively conveys the charm of Kakkon’da Gorge and provides practical information useful for those planning a visit.
About Kakkon’da Gorge | Natural Sculptural Beauty Created by Mount Iwate
Kakkon’da Gorge is a valley formed by volcanic activity on the southern slope of Mount Iwate, stretching approximately 10 kilometers from Genbu Cave to Takinoue Hot Spring, serving as a treasure trove of natural beauty. Located in Nishi-ne, Shizukuishi Town, Iwate County, Iwate Prefecture, the terrain was formed through the process of lava flowing from the initial eruptions of the Abashiri volcano cooling and solidifying, creating today’s landscape.
The gorge’s greatest characteristic lies in its diversity. Steep precipices, clear streams, and rich forests unite to create a scenic area that displays different aspects in each season, attracting not only local residents but also many tourists from outside the prefecture.
Geological Value and Natural Environment
Kakkon’da Gorge possesses exceptionally high geological value, particularly with Genbu Cave’s columnar jointing designated as a National Natural Monument. The unique structure of this formation—where lava cooling created regular cracks and hexagonal columns bundled together—is a precious natural heritage that conveys the history of volcanic activity to the present day.
Approximately 8,000 hectares of pristine beech forests spread throughout the basin, with diverse broadleaf trees such as maple, acer, and rowan naturally occurring here. This rich forest ecosystem plays an important role as a habitat for wildlife, and with luck, one might spot traces of Japanese serow or Asian black bears.
Genbu Cave (Genbu no Daiiwaya) | Spectacular Columnar Jointing
The representative landscape of Kakkon’da Gorge is Genbu Cave (玄武洞), also known as “Genbu’s Great Rock Cavern.” A precipice of columnar jointing approximately 70 meters high, continuing for about 160 meters along the Kakkon’da River, is truly breathtaking.
Formation Mechanism of Columnar Jointing
The columnar jointing of Genbu Cave was formed through the cooling and solidification process of basaltic lava that flowed out due to Mount Iwate’s volcanic activity. As the lava cooled uniformly, volume contraction created regular cracks (jointing), from which columnar structures based on hexagons emerged.
Formed through this geological process, Genbu Cave is highly evaluated academically for its scale and excellent preservation, and is utilized as teaching material in geology and volcanology.
Points for Observation
When observing Genbu Cave, focusing on the following points allows for deeper enjoyment of nature’s sculptural beauty:
- Regularity of columnar jointing: Arrangement patterns of columns based on hexagons
- Height and continuity of rock walls: The grandeur of a 70-meter height continuing for 160 meters
- Color variations: Changes in rock surface color depending on season and time of day
- Harmony with vegetation: Contrast between plants rooted in rock walls and the rock itself
There are easily observable viewpoints around Genbu Cave, and the scenic landscape can be safely enjoyed from the road along the gorge.
Toriko Falls | Silver Flow Cascading into Deep Green Pools
Another highlight of Kakkon’da Gorge is Toriko Falls (鳥越の滝), located in the deeper part of the gorge. With a drop of approximately 30 meters, the falls cascade down the rock face into a deep green pool, creating a magnificent sight with thunderous sound and white mist.
Characteristics and Scenery of the Falls
Toriko Falls is a straight waterfall on the main flow of the Kakkon’da River, appearing particularly dramatic during high water periods. The area surrounding the falls is enclosed by steep rock walls and rich forests, allowing one to simultaneously feel both the beauty of nature’s sculpting and the power of water.
The vicinity of the pool displays a deep green hue, and this mysterious color has captivated many photographers and nature enthusiasts. Particularly during the new foliage season and autumn leaves, the surrounding vegetation and the white flow of the waterfall create beautiful contrast.
Access and Observation Tips
Toriko Falls is accessed on foot from a parking space via the road along Kakkon’da Gorge. While the walking trail to the falls is well-maintained, some sections have slippery footing, so visiting in comfortable walking shoes is recommended.
The best timing for photography is during morning hours when soft light filters in. The water spray glimmers and rainbows sometimes appear.
