The cherry trees of Okuhida-Onsengo begin to blossom around the end of April each year. This is about 1 month later than in the flatlands. The cherry blossoms of Tochio-Onsen Horadani are especially beautiful. During the period of the cherry blossom festival, the paths lined with cherry trees and the public open-air spa "Kojin-no-yu" are lit up with paper lanterns in celebration of the late-coming spring of Okuhida-Onsengo.
