Lake Biwa, Japan’s largest lake, occupies approximately one-sixth of the prefecture's area, and is a place dotted with rare scenery, such as Shirahige Shrine, which has a torii gate that floats on the lake, and Ukimido Temple, the enshrinement hall of which does the same. You can enjoy "suigo meguri," water channel boat tours which cruise the waterways in the city of Omihachiman.

Also, this land has been a major traffic point since ancient times and flourished as a place with an advanced culture and economy. There are many popular sights, such as Hikone Castle, a famous castle designated as a national treasure, Hieizan Enryakuji Temple, which was founded in 788, and Eigenji and Kongorinji Temples, famous for their red autumn leaves. Koka is home to the Koka Ninja, and also has Koka Ninja Village, a theme park where you can enjoy getting into the ninja mood.
