A temple of the Kouyasan-Shingon sect, Shikoku's Star Valley Temple is located in Katsuura Town. Its chief object of worship is Ekādaśamukha, the Eleven-Faced Kannon. It is the inner sanctuary of Tatsue Temple, the 19th temple of the 88 temples of Shikoku. It was said to have been built by Kuukai in 792.

Legend says that long ago, Kuukai pulled down an evil star that was causing misfortune to people and sealed it in this temple's rockery. When the evil star turned into a stone, this stone was enshrined.
