A festival called Bakkansai (wheat appreciation festival) is held to increase publicity as the largest wheat production site in Japan.

The flying Heike Fireflies (luciola lateralis) raised by the Moor Onsen paint the night skies of Tokachigawa Onsen during the short summer period. Although the fireflies disappeared once due to urbanization, the town brought them back by creating a "creek" using hot springs. At the "creek" inside the Tokachigaoka Park where fireflies gather, firefly viewings are held for about 2 weeks starting at the beginning of July. The sight of fireflies painting the summer night sky is quite magical.
