Mt. Ishizuchi

Mt. Ishizuchi.

Mt. Ishizuchi is the chain mountain. Four iron chains, the earliest dating to the eighth century, hang down the summit cliffs in a sequence that the pilgrim is meant to climb in order. The shikemai-no-kusari — the test chain — comes first, an introductory pull of about thirty meters that the pilgrim uses to determine whether to continue. Then the first chain (ichi-no-kusari, 33 meters), the second chain (ni-no-kusari, 65 meters), and the third chain (san-no-kusari, 68 meters), each progressively longer and steeper than the last. Pilgrims who wish to bypass them can take a wooden walkway around. Pilgrims who wish to do the practice take the chains.

The chains are not for tourism. They are how Ishizuchi has trained mountain ascetics for over twelve centuries. The mountain is the highest peak in western Japan, and tradition holds that En no Gyōja himself opened it in the seventh century, recognizing in its severe rock summit a natural temple for the kind of body-discipline he was developing further east at Ōmine. The Ishizuchi school of Shugendō has its own distinct lineage, its own ritual calendar, and its own annual gate-opening festival each July when white-robed yamabushi from across western Japan converge on the mountain.

The chains test specific things. You cannot hold them with one hand; the gradient is too steep. You must commit both hands. Once you are halfway up, retreat is harder than continuing. The wind cuts horizontally across the cliff face. The rock is wet much of the year. The chains themselves are heavy — old, thick, hand-forged links worn smooth by twelve hundred years of palms and boot-edges. The links sometimes ring against each other in a strange dull music. You can hear yourself breathing.

What the chains teach is not bravery. It is a particular kind of present-tense attention. Halfway up, with both hands occupied, no possibility of stopping to think — the practitioner discovers what their body actually knows. The mind goes quiet not because it is forced to but because it is not needed. The body climbs. This, in the Shingon-aligned tradition of Ishizuchi, is the actual practice — direct experience without the mediating layer of thought.

The summit is at 1,982 meters. From it, on a clear day, you can see five old provinces — Iyo, Sanuki, Awa, Tosa, and the southern edge of Aki — the entire shape of Shikoku spread below, with the Inland Sea glittering to the north. The summit ridge is rarely empty of cloud; you may stand in white mist for an hour with no view. Then it parts, and you see, and you remember why you came up.

The annual gate-opening festival at the start of July is one of the most active Shugendō events in Japan. Hundreds of yamabushi participate. Conch horns echo off the cliffs. The chains, polished by use, gleam darkly in the morning light. The body knows things the mind does not. The chains are how the mountain teaches that.
