LAKE & SHRINE
Lake Ashi, Hakone Shrine & the Lakeside Torii
The red gate standing in the water is Hakone's signature image. Behind it lie a drowned volcano, a 1,200-year-old shrine and the old road to Edo.

Lake Ashi — Ashinoko — is the still centre of Hakone, and it is a volcano's grave. When Mount Hakone erupted violently around three thousand years ago it blew out and collapsed the crater, and the long, narrow lake that now fills the caldera floor is the water that gathered in the hollow left behind. That origin explains its shape and its stillness: it is deep, cool and hemmed by forested ridges, with the sulphur vents of Ōwakudani steaming on the rim above as a reminder that the mountain is only resting. On a clear, calm morning the surface goes to glass and mirrors the sky, and Fuji — when it shows — stands reflected off the far shore. It is beautiful in an unhurried, elemental way, and understanding that you are looking at a drowned volcano rather than an ordinary mountain lake changes how you see it.
Crossing by pirate ship
The most popular way onto the water is aboard the sightseeing boats, several of which are built as flamboyant mock galleons — gilded, many-decked and cheerfully unserious, a hit with children and quietly enjoyed by everyone else. They cross between Tōgendai, near the foot of the ropeway, and the piers at Hakone-machi and Moto-Hakone on the southern shore, taking somewhere between 25 and 40 minutes depending on the route. The ride is the calm reward at the far end of the loop's climbs, and from the open decks you get the lake's best angles: the torii standing in the shallows, the cedar-dark ridges, and on a fine day Fuji down the length of the water. The boats are covered by the Hakone Free Pass, and for many visitors the crossing is a highlight in its own right rather than just a way to the shrine.
Hakone Shrine, older than the checkpoint
On the wooded southern shore, reached by a long avenue of ancient cedars and a climb of stone steps, stands Hakone Shrine — one of the region's oldest and most atmospheric sites. Tradition dates its founding to the year 757, and its present buildings to a rebuilding in 1667, though the sense of age is everywhere in the moss, the tall trees and the lantern-lined path. It has long drawn the powerful: Minamoto no Yoritomo sheltered here after a defeat in the twelfth century and became a patron once he rose to shogun, and Tokugawa Ieyasu had it rebuilt after the Battle of Odawara in 1590. Travellers on the old Tōkaidō highway stopped to pray for safe passage over the pass, and the shrine still radiates that role — a place of protection at the threshold of the mountains, quietly busy with visitors seeking the same today.
The torii standing in the water
The image that defines Hakone is the vermilion gate rising straight out of the lake: the Heiwa no Torii, the Torii of Peace. It was built on the shore in 1952 to mark the San Francisco Peace Treaty and the end of the Allied occupation of Japan, and in 1964 a plaque bearing the character for peace was added, its calligraphy by Yoshida Shigeru, the prime minister who had signed the treaty. It serves as a symbolic gateway to Hakone Shrine, approached from the water, and its reflection in a calm lake — with the caldera and, if you are lucky, Fuji behind — is the single most photographed scene in the region. Expect a queue on the small jetty for the picture; it moves, and the wait is part of the experience. Early morning gives the calmest water and the softest light.
The nine-headed dragon of the lake
Lake Ashi has a legend, and it is worth knowing before you visit. The story tells of a fearsome nine-headed dragon that once terrorised the area until a monk subdued and reformed it; the creature became a protective deity of the water, and it is enshrined as Kuzuryū, the Nine-Headed Dragon. There is a Kuzuryū shrine on the lakeshore — the original, reached most easily by boat or on foot through the forest — and an allied shrine within the Hakone Shrine grounds, where visitors draw water from nine dragon-head spouts. The dragon is associated with blessings in love and relationships, which has made these shrines quietly popular, and a monthly water-offering ceremony still takes place on the lake. It is a good example of how thoroughly Hakone layers myth over geology: the same water that fills a dead volcano is also, in the older telling, the home of a tamed dragon.
The old checkpoint and the cedar road
Between the two southern piers lies the historical heart of the lakeshore. Because the Tōkaidō highway between Edo and Kyoto had to climb the Hakone Pass, the Tokugawa shogunate planted a checkpoint — the Hakone Sekisho — here in 1619 to control who moved between the cities, inspecting travellers, and watching especially for weapons entering Edo and women leaving it, until the system was abolished in 1869. The site was excavated and a faithful reconstruction on the original foundations opened in 2007, with guardhouses, a lookout and displays you can walk through. Nearby, a surviving stretch of the old Tōkaidō runs beneath a magnificent avenue of cedars planted for shade in the same era. Together they let you stand on the actual road that every traveller between the shogun's capital and the emperor's once trod — a rare, tangible piece of Edo-period Japan, a few minutes' walk from the torii.
