The Fushino River runs through the center of the Yamaguchi Basin from north to south, and urban areas are formed on both sides of the river.
The area of Yamaguchi was part of the ancientSuō Province. During theMuromachi period it was ruled by theŌuchi clan, who at their height ruled over six provinces in theChugoku region of western Japan. The Ōuchi clan claimed descent from the royal house ofBaekje and grew wealthy due to extensive trade with Korea andMing Dynasty China. After theOnin War, they welcomed intellectuals who escaped fromKyoto, such that Yamaguchi prospered as a center of culture. Later in the Muromachi period, Christian missionaries from Spain and Portugal were welcomed, and the area became an early center for theKirishitan faith. The Ōuchi were eventually overthrown by their vassals, theMōri clan, who ruled the area as part ofChōshū Domain during theEdo Period.
