Abstract
The cities of Sôka of Saitama Prefecture, and of Sagamihara of Kanagawa Prefecture, have been developed as industrial cities adjacent to the Keihin industrial area. The former lies in the northeastern part of Keihin, and the latter, in the southwestern.
The industrial development of both Sôka and Sagamihara shows strong ties to that of the central Keihin industrial area in that Sôka has become a satelite industrial city, and a center for miscellaneous light industries related to the Jôtô district; while Sagamihara has grown into an assembly point for mechanical commodities related to the Jônan district.
