Kasumigaura is the Japan's second largest natural freshwater lake after Lake Biwa, and is located about 60-90 kilometers northeast of Tokyo at the south part of Ibaraki Prefecture.
Kasumigaura was originally a bay and from the 10th to 15th century, sand carried by many rivers had been deposited, so it became a brackish lake. In the 1960s, purification of brackish water was done, now it is a freshwater lake.
Lake Kasumigaura is also known for the hobikibune, these are the sailed fishing boats that have been used for centuries. There is also an old one in the small museum, which is housed in a castle structure, on the east shore of the lake.
