Lake Ikeda

This crater lake has a circumference of 15 kilometers and reaches a depth of 233 meters, making it the largest such lake in Kyushu. Its clear, blue surface is a sight to behold, and a variety of seasonal flowers adorn the lakeside, making for an enchanting scene. The rape blossoms that bloom in January are especially gorgeous. The lake is also home to large eels that reach two meters in length and 50 centimeters in girth, but it is most famous for being the abode of the legendary monster “Issie.”
