Banna-ji (鑁阿寺) is a Buddhist temple of the Shingon sect in Ashikaga, Tochigi. The honzon of the temple is a statue of Dainichi Nyōrai, leading to the temple's nickname of Dainichisama. The temple is built on the ruins of the ancestral fortified residence of the Ashikaga clan, who ruled Japan during the Muromachi shogunate, and its grounds are a National Historic Site.
