Kumoi no taki is one of the main waterfalls along Oirase Stream. I think it is one of the tallest waterfalls located along the Oirase Stream. I was there with my relatives and colleagues in April 2016, July 2017 and lately April 2019. It is one of the waterfalls easily accessible by the roadside, usually tourist or locals will alighted from the buses or cars to take pictures or to pose for pictures. It is one of the popular waterfalls and I think you will not missed it as you travel from Choshi Otaki falls downstream to the Oirase Keiryu Museum.
