In ancient Japan there was a unique land system concerning allotment and allocation which was called “Jori system.” So far, many geographers have been studying about the system from historico-geographical point of view.The purpose of the present paper is in an attempt to clarify the distribution and morphology of the Jori system in ancient Awa province (Prefecture of Tokushima at present) in order to approach general principles of the system in ancient Japan. Especially, the relationship between ancient administrative districts and regionalism was investigated to reveal the political backgrounds of the system.The main findings are as follows:(1) The Jori system in ancient Awa province was divided into three areas: the central area of the Yoshino-river alluvial plain (Miyoshi-gun and Mima-gun), the lower area of the plain (Oe-gun, Awa-gun, Itano-gun, Myozai-gun and Myodo-gun) and Minami-gata (Katsu'ura-gun and Naka-gun). In the lower area of the plain, Many Jori land allotment systems are found as seen in Figs. 1, 2, 3 and 4. However, the direction of most Joris is N 10°W even though they are apart situated each other. Therefore, each Jori seems to be constructed under the same planning. The real direction is based on the inclination of the Akui-river delta-fan that the Awa Kokufu (administrative town of ancient Awa province) was situated on.(2) It may be stated that the Jori system in the lower area of the plain was planned by the Awa-ooshinoatae family ruled this area 6th through 8th centuries as the “Kuninomiyatsuko.” Guns established immediately after the Taikanokaishin (revolution in A.D. 645) were divided into five districts with straight line boundaries each accoridng to the Jori system, and their original boundaries are still present in part even now as seen Fig. 1.(3) The Niijima manor established in A.D. 749 under the rule of the Todaiji temple owned 42cho, 8tan and 162bu (about 52ha.) area. This manor was sited on the lowland along the Yoshino-river or its former course near the coast as seen in Figs. 5 and 6, however that was destroyed by frequent floods of the river. In addition, a small Jori system is also found near the manor.
