Ohmi is the region that occupies the space between the major cities of Kyoto and Nagoya. A large part of Ohmi is water – the huge Lake Biwa, Japan’s biggest lake, which is easily mistaken for the sea. From the eastern shore of Lake Biwa extends a broad plain, ideal for growing rice and raising livestock.
The keep of Hikone Castle is one of several Japanese castles designated as a national treasure. It’s registered as a special national historic site on the provisional World Heritage list. Various other features of the castle are designated important national cultural properties. The construction of the castle began in 1604, and it took about twenty years to complete by 1622. Hikone Castle is also known as Kinkame (golden turtle) Castle.
