Izu, Shizuoka

The train ends at修善寺駅, and from there the roads climb quickly into mountain terrain. Much of the municipality is forested, the slopes divided by the upper reaches of the Kanogawa watershed, and the air shifts noticeably as you move inland from the coast toward the ridgeline. 伊豆市 was assembled from four towns in the early 2000s, and its breadth shows — the Pacific-facing hot spring town of 土肥温泉 and the cedar-shaded lanes around 修善寺温泉街 feel like separate worlds joined by a single administrative boundary.

What grounds the area economically and culturally is the land itself. 天城山 receives rainfall in quantities that sustain the cold, clear streams required for わさび cultivation, and the terraced beds along those streams have been worked since the Edo period. Shiitake grows here too, quietly, alongside the wasabi. At 浄蓮の滝, a waterfall drops into a gorge where wasabi fields spread below the spray — a place where the logic of the landscape becomes visible in a single glance.

修禅寺, founded by Kūkai and later the site of the confinement of the shogun Minamoto no Yoriie, sits at the center of the old hot spring quarter. The inn 新井旅館, established in the Meiji era and associated with Japanese painters and literary figures, still operates nearby. The 天城山隧道, a stone tunnel cut through the mountains in the Meiji period, now stands as a registered cultural property — the kind of infrastructure that outlasted its era and became, almost incidentally, a record of how people once moved through this difficult terrain.
