Sukagawa, in central Fukushima Prefecture, is celebrated as Japan's foremost peony city, home to the magnificent Botan-en peony garden, a National Natural Monument containing over seven thousand peonies of three hundred varieties that bloom spectacularly each spring. Sukagawa Onsen Peony draws on chloride-rich thermal waters from Fukushima's volcanic subsurface, providing soothing baths that warm visitors through the city's characteristically cold inland winters. The town is also celebrated as a hub of traditional Japanese fireworks culture, with Sukagawa's November fireworks festival drawing crowds from across the Tohoku region each autumn.
Insider tip — Sukagawa is a commercial city in the Naka River valley of central Fukushima, better known for its Tokiwa fireworks festival than for tourism, which means its sodium-chloride thermal facility operates primarily for local residents. The salty, warming waters are ideal for the long Tohoku winters and are priced at a fraction of resort-area onsen. The city's famous giant Ultraman statue stands a short walk from the main bathing district, a quirky landmark for visitors.
