Opening
Three shrines anchor the Kumano Kodo network across the Kii Peninsula's forested mountains: Hongū Taisha inland at the confluence of the Kumano River's tributaries, Hayatama Taisha where that river meets the sea at Shingū, and Nachi Taisha above Japan's tallest waterfall to the south. For over a thousand years — emperors, retired emperors, aristocrats, and eventually pilgrims of every rank — walked mountain trails between them, a practice so dense with movement it became known as "ant pilgrimage" (ari no kumano mairi) for how continuously the paths were used.
Origins
Each shrine's origin story centers on divine descent. At Hongū, tradition holds that three moons fell from the sky around 33 BCE and settled in an oak tree at Oyunohara, the sandbar where the Kumano River's tributaries meet; a voice proclaimed itself the deity Shōjō Daigongen and commanded a shrine be built there (the current shrine relocated to higher ground after an 1889 flood destroyed the original complex). At Hayatama, the creator deities Izanagi and Izanami are said to have first alighted on Gotobiki Rock, a massive toad-shaped boulder still venerated above the shrine. At Nachi, worship predates any built shrine — prehistoric peoples recognized Nachi Falls itself, Japan's tallest single-drop waterfall, as the seat of the deity Hiryū Gongen, and the shrine now sits beside the falls it was built to formalize, not replace, since the falls themselves remain an object of direct worship.
Why pilgrims walk it
The Kumano pilgrimage historically drew on a distinctive theology: this was one of the few places where Shinto kami-worship, Buddhist rebirth practice, and mountain ascetic Shugendō training overlapped so thoroughly that visiting all three shrines was understood as a journey through death and rebirth — descending into the mountains as into the Buddhist Pure Land, then returning purified. Retired emperors made the journey dozens of times in some cases; by the medieval period commoners followed in such numbers the trails earned their "ant pilgrimage" nickname. Modern walkers come for a mix of the same renewal-seeking and for the trail itself, recognized alongside Spain's Camino de Santiago as one of only two pilgrimage routes with UNESCO World Heritage status, with an official dual-pilgrimage credential (green stamp) available to walkers who complete both.
Significance
The three shrines are not interchangeable stops but distinct sacred geographies that together map the region's full landscape: Hongū at the river confluence represents the mountain interior, Hayatama at the river mouth represents the boundary between land and sea, and Nachi at the waterfall represents the vertical descent of divine power from the heights. Each also enshrines a different configuration of Kumano deities (gongen) under Shinto-Buddhist syncretic identifications built up over the medieval period, and each has its own architecture, festival calendar, and founding narrative — visiting only one gives a partial and misleading picture of what the pilgrimage as a whole represents.
