Complete Guide to Kobugarahara Highland (Tochigi Prefecture) | Hiking and Seasonal Scenic Beauty at a Shugendo Sacred Site
What is Kobugarahara Highland?
Kobugarahara Highland (古峰ヶ原高原) is a highland plateau located at an elevation of approximately 1,200-1,300 meters in Kusaku, Kanuma City, Tochigi Prefecture. Spread near the border between Kanuma City and Ashio Town in Nikko City, this highland has been known since ancient times as a sacred site for ascetic practice and meditation, where Shodo, the founder of Nikko, is said to have conducted his training according to mythology.
Today, it is gaining popularity as a hiking spot where visitors can enjoy beautiful natural landscapes from spring through fall, with particularly large numbers of climbers and nature enthusiasts visiting during the azalea blooming season. The highland area spreading behind Furuminejinja Shrine is also known as a sacred site for tengu (mountain goblin) worship, creating a unique atmosphere where history and nature are fused together.
History and Faith of Kobugarahara Highland
Shodo and the Shinjinbar Retreat
The history of Kobugarahara Highland is deeply connected to the ascetic practice of Shodo (勝道上人), who was active from the late Nara period through the early Heian period. Before opening Nikko, Shodo spent three years of training in the mountains of Kanuma. His ascetic practice site was called “Shinjinbar no Shuku (深山巴の宿),” located in the central part of Kobugarahara Highland.
Shinjinbar no Shuku remains a sacred place where ascetic monks accumulated rigorous training, still exuding a spiritual atmosphere today. Following his training at this site, Shodo is said to have successfully climbed Nantai Mountain in Nikko and established the opening of Nikko Shrine.
Tengu Worship and Furuminejinja Shrine
At the foot of Kobugarahara Highland stands Furuminejinja Shrine (古峯神社), known for tengu worship. This shrine is nationally famous as the “Shrine of the Tengu” and is widely revered as a deity protecting against fire and theft. The path leading from Furuminejinja Shrine to Kobugarahara Highland is also an ancient ascetic training route once walked by mountain monks, and its historical atmosphere can still be felt today.
Kobugarahara Wetland and Natural Attractions
Characteristics of Kobugarahara Wetland
The area surrounding Shinjinbar no Shuku is called Kobugarahara Wetland, featuring marshland characteristic of highlands. Located at elevations exceeding 1,200 meters, this wetland provides a valuable natural environment where diverse plants thrive due to the cool climate and abundant moisture.
Wooden pathways have been installed around the wetland, allowing visitors to enjoy walking without damaging the marshland. Surrounded by silence, the wetland serves as a healing space that helps visitors forget the bustle of the city, and it is cherished by many visitors.
Spring Azalea Hotspot
Kobugarahara Highland becomes most crowded during the azalea blooming season from spring through early summer. Particularly from late May through early June, various types of azaleas—including Yama-azalea, Flame Azalea, and Deciduous Azalea—paint the entire highland.
Main types of azaleas:
- Flame Azalea: Vivid reddish flowers bloom in clusters, turning the highland red
- Yama-azalea: Deep pink flowers color the mountainside
- Deciduous Azalea: Delicate pale pink flowers announce the arrival of spring
These azaleas grow naturally around Kobugarahara Wetland and along hiking trails, allowing visitors to enjoy beautiful flowers while hiking. Simultaneously with the azaleas, small pear blossoms also bloom, creating a beautiful contrast with the red and pink azaleas.
Summer and Autumn Highland Scenery
In summer, fresh greenery is beautiful, and the cool highland climate makes it ideal as a summer retreat. Due to the high elevation, temperatures are approximately 5-10 degrees Celsius lower than in the lowlands, allowing for comfortable hiking.
In autumn, fall foliage colors the highland, with beech, maple, and rowan trees turning yellow and red. Late September through mid-October is the prime viewing period for autumn leaves, offering a different kind of beauty from the spring azaleas.
