Lake Inba

Lake Inba (印旛沼, Inba-numa) is a man-made polder lake consisting of northern and western sections connected by a canal and located in Inba Tega Prefectural Natural Park in the Tone River basin in Chiba Prefecture, Japan. It is the largest lake in the prefecture. It was formed from remnants of the Katori Sea after the Tone River was diverted. It is a popular location for outdoor activities, including fishing, bicycling, and birding, and is home to numerous species of plants, birds, and other wildlife. The National Museum of Japanese History is located on the grounds of the ruins of Sakura Castle, southwest of the lake. It is easily accessible through a number of train and bus services. The lake is also variously known as Lake Imba, Lake Imbanuma, Inbanuma, and Imbanuma.
