Mount Kamiyama: Discovering Hakone’s Spiritual Heart
When travelers dream of Hakone, images of steaming onsen, the sparkling waters of Lake Ashi, and the majestic silhouette of Mount Fuji often come to mind. Yet, looming silently above these popular attractions is the geological and spiritual father of them all: Mount Kamiyama (箱根の神山). As the highest peak in the Hakone caldera, Kamiyama is more than just a mountain; it is the sacred center that shaped the land and defined the region’s ancient worship.
Introduction
Standing at 1,438 meters (4,718 feet), Mount Kamiyama—literally translating to “God Mountain”—is the central cone of the Hakone volcano complex. While the ropeway cars glide past its slopes carrying tourists to the sulfur fields of Owakudani, few realize that they are skirting the edge of a sacred site that has been worshipped for millennia. For the intrepid traveler and the culture enthusiast, Kamiyama offers a blend of raw volcanic power and deep religious history, serving as a reminder that in Japan, nature and divinity are often one and the same.
Origins: The Birth of the Central Cone
To understand the spiritual weight of Kamiyama, one must first understand its violent birth. Hakone is a massive volcano with a complex history of eruptions. Approximately 3,000 years ago, a massive phreatic eruption occurred on the northwestern slope of Kamiyama. This cataclysmic event caused a landslide that dammed the Hayakawa River, creating the iconic Lake Ashi that tourists cruise upon today.
This explosion also birthed Owakudani, formerly known as O-jigoku or “Great Hell.” The contrast between the lush, green summit of Kamiyama and the steaming, sulfurous vents of Owakudani below represents the duality of nature—life and death, creation and destruction. In ancient times, people looked up at the verdant peak towering above the “hell” valley and saw a dwelling place for the gods, leading to the mountain’s sanctification.
Legend: The Monk and the Dragon
The spiritual history of Kamiyama is inextricably linked to the founding of the Hakone Shrine. According to legend, during the Nara period (around 757 AD), a high-ranking Buddhist priest named Mangan Shonin visited the region. At the time, the area was feared due to the toxic gases and the terrifying noise of the volcanic earth.
Mangan Shonin, seeing the divine potential in the terrifying landscape, climbed Mount Kamiyama to perform ascetic practices. Following a divine revelation, he established a place of worship for the local deities—the Hakone Okami. This marked the formal beginning of Sangaku Shinko (mountain worship) in Hakone.
Perhaps the most famous legend involves the Nine-Headed Dragon (Kuzuryu) that lived in Lake Ashi, terrorizing local villagers. Through the spiritual power gained from his austerities on Mount Kamiyama, Mangan Shonin subdued the dragon, chaining it to rocks at the bottom of the lake. The dragon transformed into a protector deity, now worshipped alongside the mountain gods at the Kuzuryu Shrine. Thus, Kamiyama is viewed as the source of the spiritual power that tamed the chaotic forces of the land.
Modern Culture: A Hiking Haven and Power Spot
In contemporary Japan, Mount Kamiyama is revered as a major “Power Spot”—a location thought to be charged with spiritual energy that revitalizes visitors. The mountain sits at the center of the Hakone three-shrine pilgrimage, which includes Hakone Shrine, Kuzuryu Shrine, and Mototsumiya (located on the neighboring peak, Mount Komagatake).
Culturally, the mountain serves as the backdrop for the famous Hakone Ekiden, a university relay marathon, reminding spectators of the rugged terrain that defines the area. Furthermore, the famous black eggs (kuro-tamago) sold at Owakudani are cooked in the hot springs heated by Kamiyama’s magma chamber. Eating one is said to add seven years to your life, a modern superstition rooted in the ancient reverence for the mountain’s life-giving heat.
Traveler’s Tips: Conquering the Peak
Visiting Mount Kamiyama requires more planning than the average Hakone sightseeing trip. Because it is an active volcano, access is heavily dependent on the Japan Meteorological Agency’s volcanic alert levels.
- Check the Status: Before planning a hike, always check the volcanic alert level. If the level is raised, the hiking trails connecting Owakudani and Mount Komagatake via Kamiyama are closed strictly for safety.
- The Route: When open, the most popular hiking route is a traverse. You can start from the Hakone Komagatake Ropeway station, hike up to the summit of Kamiyama, and descend toward Owakudani (or vice versa). The trail is steep and can be slippery with clay-like soil, so proper hiking boots are mandatory.
- The View: The summit of Kamiyama is covered in dense trees, so panoramic views are limited at the very top. However, the trail offers breaks in the canopy where you can see Mount Fuji and the glittering Sagami Bay.
- Alternative Worship: If the trail is closed, take the Hakone Komagatake Ropeway to the summit of the adjacent Mount Komagatake. Here lies the Mototsumiya Shrine. Since Kamiyama was historically too sacred (and dangerous) to enter frequently, this shrine was built on the neighboring peak to worship Kamiyama from a distance.
