Mt. Ishizuchi — The Highest Peak in Western Japan, Sacred Chain Climbs

Trail Overview

Mt. Ishizuchi (石鎚山, 1,982m) in Ehime Prefecture, Shikoku, is the highest mountain in western Japan and one of the country’s most sacred peaks. Revered for over 1,300 years as a centre of shugendo (mountain asceticism), it ranks among Japan’s Seven Sacred Mountains.

The defining feature of Ishizuchi is its series of four iron chain climbs — Tameshi-no-kusari (the Practice Chain), Ichi-no-kusari, Ni-no-kusari, and San-no-kusari — fixed to near-vertical rock faces. Gripping these thick chains and hauling yourself up the cliff is a visceral, deeply Japanese mountain experience unlike anything else in the country. Bypass trails exist for every section if you prefer.

The highest point, Tengudake (天狗岳, 1,982m), is a dramatic rock pinnacle reached by traversing a narrow, exposed ridge from the main summit of Misen (弥山, 1,974m). Many hikers are content to stop at Misen, which has a viewpoint and the Ishizuchi Summit Shrine.

Recommended Route: Ropeway + Omando (Main Pilgrimage Trail)

Take the ropeway to Joju Station, visit Joju Shrine, then follow the Omando (main trail) via the chain sections to Misen and optionally Tengudake.

Course Time

Section	Duration
Ropeway Joju Station → Joju Shrine	About 10 min
Joju Shrine → Hachojo-zaka (before Tameshi chain)	About 50 min
Tameshi-no-kusari / bypass	About 20–30 min
Ichi-no-kusari + Ni-no-kusari / bypass	About 30–40 min
San-no-kusari → Misen Summit	About 30 min
Misen → Tengudake (one way)	About 15 min
Total (ascent, chain route)	About 2 hrs 50 min
Total (descent)	About 2 hours

Tip: The ridge walk to Tengudake involves narrow, exposed sections with steep drops on both sides. If you have a fear of heights, or if the weather is wet or windy, turning back at Misen is the wise choice. Misen already offers sweeping views over Shikoku and the Seto Inland Sea.
