It began with one monk and a handful of maple seedlings.
In the early Edo period, the abbot of Korankei's temple planted maples along the approach to the hall—a small act, the kind that usually vanishes. But his successors kept planting, and the planting kept going, and now some four thousand trees of eleven different maple species fill the gorge along the Tomoe River.
The variety is the point. Because no two species turn at quite the same moment or to quite the same shade, the autumn here is never uniform: scarlet beside vermilion beside orange beside a stubborn lingering green, the reds layered rather than flat. In the evening the trees are lit, and the leaves reflected in the river show a color the daylight never gave them, doubled and slightly wrong, the way reflections always are.
What moves you, if anything does, is the arithmetic of patience. A single planted tree, and then three hundred years, and at the end of it an entire valley gone red. It is the kind of project no one alive ever sees finished, which may be why it was worth starting at all.
The road into Shitara narrows as the mountains close in, and by the time the valley opens again, the air has changed — cooler, quieter, carrying the smell of cedar and moving water. The Toyokawa and its tributaries cut through this deeply forested corner of northeastern Aichi, where the surrounding slopes are almost entirely woodland. This is Oku-Mikawa, and Shitara sits at its center.
The town's history runs deep beneath the surface. Obsidian was worked here in the Paleolithic period, and the ground has given up evidence of continuous settlement ever since. In the medieval period, the Suganumasshi clan held this territory from Tamine Castle, a fortification whose wooden main hall has been reconstructed on its original site. The castle changed hands between Takeda Shingen and Oda Nobunaga, and the weight of that contested past lingers in the landscape. At Tsugu, the local folk museum preserves over a thousand everyday objects from the Edo through Shōwa periods, alongside records of the Tsugu gold mine — a reminder that this mountain interior was once economically significant.
What continues to animate Shitara is its ritual calendar. The Hana Matsuri, a festival of ancient origin, and the Mikawa Dengaku are not performances staged for outsiders; they are living observances tied to specific shrines and temple grounds, including Tamine Kannon at Kōshōji. Tamine-cha, the local tea, and karasumi are produced quietly in this agricultural economy that also runs to tomatoes and rice. The Michi-no-Eki Shitara, opened in 2021, houses the Oku-Mikawa Folk Museum alongside its road-stop function — a practical building that doubles as an archive of the valley's material life.
