Numappara marshland is subalpine zone located at 1,230 meters high, 250 meters from east to west, and 500 meters from north to south of the west end of the Nasu mountain range. This marshland is a start of the mountain trail as well.
230 kinds of plants are already confirmed there. The following are the main plants: Symplocarpus foetidus in spring, malus toringo in early summer, hemerocallis dumortieri, veratrum, iris ensata, filipendula multijuga, salvia japonica, and gentiana triflora. You can see these plants while you walk around the street constructed in the marshland. Especially the end of June to the middle of July, the season of hemerocallis dumortieri, a lot of hikers visit Numappara.
The south part of marshland has an adjustment reservoir which was constructed for generating electricity in 1969. Marshland became a bit smaller, but it is taking natural environment into consideration. In addition, constructing the reservoir brought better traffic that even large-sized bus can pass through.
Historically, “Aizu-Chukaido Road”, which was built by the shogunate’s fund, was opened in 1695, and it was used for sankinkotai for four times.
