The purpose of this paper is to discuss the generation of Yokohama's aspect of direction through studying the relation of between the town name based on Yokohama's direction and the components related to natural, social-cultural or historical elements through analyzing generation pattern of relative and absolute direction. The following is the approach taken to study this matter: (1)Collecting data on the current town names of Yokohama and Extract/sort them according to direction. (2)To grasp how town names are made accordingly to direction, that is, the generation pattern in time. (3)To examine the generation pattern in space which are the relation of town names and urban space's components by visualizing the town name's spatial distribution and relations. (4)To consider the awaking generation pattern of Yokohama's aspect of direction on basis of the above. As a result, the following has been able to be made clear of: (1) There are 1370 town names in Yokohama. Of them, 194 are based on direction, 33 on UP-DOWN of relative direction, 99 on NORTHSOUTH EAST and WEST of absolute direction, 11 on CENTER/CENTRAL, 7 on MIXTURE, 44 on NO DIRECTION. Particularly there were 31 town names including EAST, and the number of combination names were 69. (2) Most of the town names based on absolute direction have rapidly increased since 1969. (3) We have visualized spatial distribution and relations as an arrow using Geographical Information System. As a result, 106 arrows/double arrows were able to be drawn, mostly along the Sakaigawa basin and the former path of Tokaido with most of them having small angular difference. Also, the lag difference between double arrows and the actual axis of four cardinal points of formerly Tachibana county, Kuraki county, Kamakura county are lagged counter clockwise while only formerly Tsuzuki county is lagged clockwise. (4) By combining generation pattern in time and space, we were able to make clear of the following 4 points. 1, The UP-DOWN axis along the Sakaigawa basin and the former main roads most notably the former Tokaido were assembled before the organization awakening of the city of Yokohama, which impact could still be seen as of now. 2, After the enforcement of the municipalism of Yokohama the reorganization of Yokohama as an city urban space that is conscious of NORTH SOUTH EAST and WEST axis is formed at formerly south Tachibana, county, north Kuraki county. 3, From 1939 and later NORTH SOUTH EAST and WEST axis is recognized at formerly south Kuraki county, Kamakura county, Tsuzuki county. 4, East, which is the direction the harbor is at from the areas where town names are named according to direction, can be seen to be particularly focused on.
