Characteristics of the Three Mountains in Kobo-yama Park
The three mountains comprising Kobo-yama Park each possess distinct charm. With low elevation and easy walking paths, a major feature is that hiking beginners can easily enjoy a ridge traverse.
Sengen-yama (196m elevation)
Sengen-yama, often serving as the entrance to the Kobo-yama hiking course, is the lowest of the three mountains. Sengen Shrine is located near the summit and is cherished as a local point of faith. Since it can be climbed in a relatively short time, it’s ideal for warming up.
Gongen-yama (243m elevation)
Gongen-yama, the highest of the three mountains, features an observation deck that is a highlight of Kobo-yama Park. From the observation deck, on clear days you can enjoy a 360-degree panoramic view of Mt. Fuji, the Tanzawa Mountain Range, Sagami Bay, and the Boso Peninsula. During the cherry blossom season in spring, the area around the observation deck is colored by blooming cherry blossoms, and the spectacular sight of blossoms bathed in morning light and tinted in soft dawn colors is a must-see.
Kobo-yama (235m elevation)
Kobo-yama, a mountain with a legend that Kobo Daishi practiced asceticism here, is the namesake of the park. The summit features Shakakudo Hall and a bell tower, allowing visitors to feel the historical atmosphere. Walking through the quiet forest path is ideal for forest bathing, refreshing both mind and body.
