Oirase Stream as a Field Museum

Until now, Oirase has mostly been considered a typical sightseeing spot useful just for overlooking the scenery below, or as one place to walk outdoors. However, there are hardly any scenic places like Oirase equally suitable for appreciating natural history and art. Visitors can enjoy compositions of nature created by various kinds of trees, flowers, ferns, mosses, mushrooms, and geological formations through a moderately maintained trail along a natural stream surrounded by near primeval forest. No excessive physical exertion is required for visitors climbing up the mountain. One can stroll along as if appreciating arts in a museum. Oirase is truly a natural historical site (field museum).
