A low earthwork in Oe Marsh survives from the Boshin War (1868–1869). Aizu-domain samurai stationed here built the mound, about 80 cm high and 12 m long.
Oe lay on the roughly 180-km Aizu-Numata road, linking Aizu in Fukushima with Numata in Gunma. At a nearby Lake Ozenuma trading post, rice and sake went one way; salt and oil the other.
Each Nikkō kisuge bloom lasts only 1–2 days, yet one plant carries 6–7 buds and opens them one at a time. This floral relay helps Oe Marsh’s yellow display last about a week.
At Oe Marsh’s western edge, Yanagiran Hill holds the Hirano family graves. Across 3 generations, the family helped protect Oze: Chozo opposed a dam, Choei resisted another, and Chosei led the campaign that stopped a road.
The deer fence around Oe Marsh is seasonal work: crews stretch about 3.5 km of barrier after snowmelt, then take it down before deep snow can damage it and deer move away for winter.
The Three Larches stand on a small mound called Oze-zuka. Local legends call it either the grave of Fujiwara no Yorimi or the archery ground of his elder brother Yorikuni—folklore, not settled history.
Oe Marsh’s summer flowers pass a baton: cotton grass’s tiny flowers become soft white seed heads in early summer, then yellow Nikkō kisuge takes over in midsummer.
Most tiny Tateyama gentians in Oe Marsh are blue, but the visitor center has also documented a rare white form and flowers with a reddish-lavender cast. Spotting one means looking close.
At the Oe River mouth, nutrient-rich water supports low-marsh plants such as skunk cabbage and marsh lobelia. The river edge is also where peat is still forming—Oe Marsh slowly builds itself into Lake Ozenuma.
