Kudan no Taki measures approximately 15 meters wide and 7 meters high, making it the largest waterfall along the Oirase Stream. It is also the only waterfall located on the main stream itself, while other waterfalls in the area flow from tributaries. Despite its size, the waterfall features a gentle flow where water runs down the rock face in a curtain-like manner, creating both an exuberant and subtle display.
