Bitchū Province was a province of Japan on the Inland Sea side of western Honshū, in what is today western Okayama Prefecture. It was sometimes called Bishū (備州), with Bizen and Bingo Provinces; those three provinces were settled in the late 7th Century, dividing former Kibi Province. Bitchu bordered Hōki, Mimasaka, Bizen, and Bingo Provinces.
