This article provides detailed explanations of the charm of Mt. Ishizuchi, climbing routes, access methods, and highlights by season.
Basic Information about Mt. Ishizuchi
Geographical Characteristics and Elevation
Strictly speaking, a single peak called Mt. Ishizuchi does not exist. Rather, “Mt. Ishizuchi” is a collective name for three main peaks: Tengu Peak (elevation 1,982m), Miiyama (elevation 1,974m), and Minami Senpo (elevation 1,982m). The highest point is Tengu Peak, which boasts the elevation of the highest peak in western Japan.
It spans Saijo City in Ehime Prefecture and Kuma Kogen Town in Kamiukenamori District, and is protected as a central mountain of the Ishizuchi Quasi-National Park. Its magnificent appearance can be seen from afar from the Seto Inland Sea and is cherished as a scenic landscape representing Shikoku.
Mountain Worship and Historical Background
Mt. Ishizuchi has been revered as a sacred site of mountain worship since ancient times. It is counted as one of Japan’s Seven Sacred Mountains and is said to have been founded by En no Ozunu, the founder of Shugendo (mountain asceticism). A summit shrine of Ishizuchi Shrine stands near the summit, and many ascetics and pilgrims continue to visit today.
During the “Mountain Opening” period from July 1st to 10th each year, a traditional event is held in which believers dressed in white visit the summit, passing down the faith culture of Mt. Ishizuchi to the present day.
Why Mt. Ishizuchi Was Selected as One of Japan’s 100 Famous Mountains
Mt. Ishizuchi was selected in Hisao Fukada’s “Japan’s 100 Famous Mountains” for its high evaluation not only for its elevation but also for its steep rocky terrain, long chain sections, rich natural environment, and cultural value of mountain worship. As the highest peak in western Japan, it is a mountain of aspiration for climbers in Shikoku, and many climbers from across the country visit this famous mountain.
Main Climbing Routes of Mt. Ishizuchi
There are multiple climbing routes up Mt. Ishizuchi, but the main ones are the following three. Each differs in difficulty level, required time, and highlights.
Jojusha Route (Front Approach Course)
The most popular climbing route, accessed using the Ishizuchi Mountain Ropeway.
- Trailhead: Jojusha Station (elevation approximately 1,450m)
- Required Time: Approximately 2.5 to 3 hours one way
- Elevation Gain: Approximately 530m
- Difficulty Level: Intermediate
This route targeting the summit via Jojusha is famous for having four chain sections: Trial Chain (approximately 33m), First Chain (approximately 33m), Second Chain (approximately 65m), and Third Chain (approximately 68m). Since there are detour routes around the chain sections, general climbers can also climb safely.
When climbing the chains, it is important to grasp the chains firmly with both hands and aim for three-point support. In particular, the Third Chain is a nearly vertical rock face and is known as a rare long chain section in Japan.
Tsuchishoyu Route (Back Approach Course)
The route that allows reaching the summit in the shortest time and is recommended for beginners.
- Trailhead: Tsuchishoyu (elevation approximately 1,492m)
- Required Time: Approximately 1.5 to 2 hours one way
- Elevation Gain: Approximately 490m
- Difficulty Level: Beginner to Intermediate
Since you can access Tsuchishoyu by car using the Ishizuchi Skyline, the climbing time is short and it is an easy route for those without confidence in their strength. Although there are no chain sections, rocky terrain climbs continue, so proper climbing equipment is necessary.
From the summit, you can see a panoramic view of the Seto Inland Sea and the mountains of the Ishizuchi range, and on clear days you can see far into the Chugoku region.
Omogo Route (Southern Approach Route)
The longest distance route for experienced climbers.
- Trailhead: Omogo Gorge
- Required Time: Approximately 4 to 5 hours one way
- Elevation Gain: Approximately 1,400m
- Difficulty Level: Advanced
This route, which allows you to enjoy the beautiful nature of Omogo Gorge while climbing, is long and requires stamina, but you can enjoy quiet mountain walking. There are mountain huts along the way, and it is also possible to climb with leisure over a two-day, one-night itinerary.
