Nagato Fuchû han, often abbreviated to Chôfu han, was a branch domain of Chôshû han. Ruled by a branch of the Môri clan, the domain was based in the city of Shimonoseki, and had a kokudaka of 50,000 koku. The lords of Chôfu were "castle-holder" (shiro-nushi or shiro-mochi) daimyô, and were assigned to the Yanagi-no-ma in Edo castle.
The Meiji period Nihonga pioneer Kanô Hôgai is among the notable figures originally from Chôfu; he was born and raised the son of Kanô Seikô, a court painter in the official service of the lords of Chôfu, and later succeeded his father to that position.
