Keichū Keichū (契沖 ) (1640 – April 3, 1701) was a Buddhist priest and a scholar of Kokugaku in the mid Edo period. Keichū's grandfather was a personal retainer of Katō Kiyomasa but his father was a "rōnin" from the Amagasaki fief. When he was 13, Keichū left home to become an acolyte of the Shingon sect, studying at Kaijō in Myōhōji, Imasato, Osaka. He subsequently attained the post of Ajari (or Azari) at Mount Kōya, and then became chief priest at Mandara-in in Ikutama, Osaka. It was at this time that he became friends with the poet-scholar Shimonokōbe Chōryū (下河辺長流, 1624–1686).
