Tenko Forest is a scenic spot in Yamanashi Prefecture designated as a natural monument. It is famous for a unique phenomenon: if you stamp your feet firmly at certain locations within the forest, a resonant sound resembling a drum echoes up from underground. Consider stopping by for a break during your autumn stroll.
