The sacred high point of Western Japan
Mt. Ishizuchi (1,982 m / 6,503 ft) is the highest mountain in Western Japan and the highest in the entire Kansai-Chūgoku-Shikoku region — every higher peak in Japan lies in the Northern, Central or Southern Alps far to the east. It is also one of Japan's Seven Sacred Mountains ('Nana Reizan'), revered for over 1,300 years as a Shugendō ascetic-training site. The mountain consists of three peaks — Tengu-dake (the true summit), Misen (where the shrine sits), and Minami-Sempō — and is climbed by perhaps the most distinctive route in Japan: a series of long iron chains hanging from the upper crags, used as climbing aids by both modern hikers and white-robed pilgrims.
Two trails, two characters
There are effectively two routes. From the north, the Jōjusha (Joju Shrine) route uses a ropeway to reach 1,300 m and follows the historic pilgrim path past four chain sections — the trial chain plus the first, second and third 'real' chains — to the summit. About three hours up. From the southeast, the Tsuchigoya route starts where a paved mountain road (Ishizuchi Skyline) drops you at 1,492 m. Only two chain sections, with bypass paths around them; about two and a half hours up. The two routes merge just below the summit shrine. Pilgrims and chain enthusiasts use Jōjusha; first-timers and hikers short on time use Tsuchigoya.
About the chains
The chains are the defining feature, and they are not a tourist gimmick. The third chain is around 68 m long with sections steeper than 60°. You are pulling your own body weight up smooth iron links bolted to the rock face. The chains are well maintained by Ishizuchi Shrine, but the act of climbing them is real climbing — both hands on the chain, body weight loaded through your arms. Every chain section has an alternative bypass route ('makimichi') if you choose not to use them, so reaching the summit without ever touching a chain is fully possible. Use gloves with grip and tuck your trekking poles inside the pack before each chain.
What to pack
Standard alpine layering for an exposed sub-2,000 m summit: long-sleeve synthetic or merino base, a fleece or wind-shell midlayer, a real rain shell, gloves (essential for the chains), and ankle-supporting hiking boots. Summer summit temperatures average 15 °C with frequent wind. Water: 1.5–2 L. There is a spring on the Jōjusha trail before the first chain but no reliable source on the Tsuchigoya side. A small detail that matters: the Tengu-dake summit ridge beyond the Misen shrine is a narrow knife-edge with vertical drops on both sides. If exposure makes you uncomfortable, the shrine point at Misen is a fine turn-around — most pilgrims historically went no further.
Access from outside Japan
From Matsuyama Airport (Ehime), the simplest path is a rental car to either the ropeway (90 minutes via Iyo-Saijō) or to Tsuchigoya via the Ishizuchi Skyline (about two hours). Public-transport access exists but is slow: limited summer-only buses serve Tsuchigoya. The Ishizuchi Skyline closes from late November to mid-April for winter, so the Tsuchigoya trailhead is effectively a summer-and-autumn option. The ropeway operates year-round (except early January), making the Jōjusha route the only realistic winter approach — but Ishizuchi in winter is a serious snow climb, not a hiking trip.
When to go
Hiking season runs late April through mid-November. The peak Japanese-pilgrim window is the Oyama-biraki festival (July 1–10), when white-robed Shugendō practitioners carry the shrine's sacred object up to Misen — visually one of the most striking living-religion scenes in the Japanese mountains. The trails are noticeably busier in this period. The other peak window is mid-October to early November, when the upper beech and rowan forests along Ishizuchi Skyline turn red and gold.
Pilgrim lodging exists at Jōju Shrine itself — bookable as a 'shukubō' guesthouse with simple shared rooms and vegetarian meals. Staying here the night before lets you start the climb at first light and gives a tangible sense of how Ishizuchi was approached for the past millennium.
From the summit: the view across Shikoku
On a clear day, Mt. Ishizuchi delivers what its geography promises: looking north, the Seto Inland Sea spreads to Honshū with the bridge complexes of Imabari–Onomichi clearly visible; looking south, the Pacific Ocean lies beyond the lower spine of Shikoku; to the east, Mt. Tsurugi (Tokushima) — the second-highest peak in Shikoku — fills the far horizon. The natural follow-up climb is Mt. Tsurugi itself, a much gentler grass-and-bamboo summit that pairs with Ishizuchi as the classic 'Shikoku Hyakumeizan double.'
