Otsuki, Yamanashi

The old road through Otsuki still follows the Kaido line — the Koshu Kaido, once a relay route between Edo and the mountains, now a national highway threading between steep valley walls. The Katsura River cuts the same gorge it always has, and the town sits wedged into whatever flat ground the water left behind. Eight stations serve a population that fits comfortably into a single mid-sized neighborhood elsewhere, which says something about how the terrain shapes movement here.

At Saruhashi, a wooden bridge spans the gorge on a system of cantilevered timber brackets — no piers touching the water below, the structure held by the logic of counterweights alone. The bridge carries a legend about a craftsman from Baekje, though the current form is Edo-period. Nearby, vendors sell Saruhashi Manju, the local sweet that appears in station kiosks and roadside shops without ceremony. At the foot of Sasago Pass, in the Nitta district, a tradition of puppet theater — Ningyō Jōruri — has been passed down since the eighteenth century, performed by the community itself rather than professional troupes.

Above the town, the peaks of Koganezawa and Karagahara-surisanyama rise into the Chichibu-Tama-Kai National Park. From the higher ridges, the silhouette of Fuji appears across the ranges. Down in the valley, Iwadono-san Entsūji temple sits on its rocky prominence, once under the protection of the Oyamada and Takeda clans. Nigomi — a local simmered dish — and Sasakomochi round out a pantry that belongs specifically to this corridor between the mountains.
