Kannonji Castle (観音寺城, Kannonji-jō) was a Sengoku period yamashiro-style Japanese castle located in what is now the Azuchi neighborhood of the city of Ōmihachiman, Shiga Prefecture, Japan. The ruins have been protected as a National Historic Site since 1982, with the area under protection expanded in 1984.^[1] The castle was named after Kannonshō-ji, a Buddhist temple near the peak of the mountain.
