Lake Ikari

An artificial lake created by the construction of a multipurpose gravity dam on the Ojika River.

Lake Ikari is a reservoir on the Ojikagawa River, downstream of Yunishigawa Dam.The lake's name, which means ""50 'ri' lake,"" is derived from the fact the lake is located 50 'ri' from Nihonbashi in Edo. During the fall foliage season from mid-October to early November, the lake and the fiery leaves of the trees on its shore create a beautiful contrast, attracting large numbers of visitors. Around May 5th each year, koinobori carp streamers can be seen ""swimming"" as they are flown from the top of Ikari Dam.""
