The purpose of this research is to clarify the locational characteristic and the locational pattern of the convenience store (hereafter to be referred as CVS) in Okayama prefecture and central city scale for Okayama Prefecture. In Okayama Prefecture, CVS are dispersed in municipalities with concentrated traffic in conjunction with national highways. CVS were initially located in Okayama city and Kurashiki city, the central cities of Okayam Prefecture, and gradually expanded to neighboring municipalities. In the northern part of Okayam Prefecture, CVS expanded to the neighboring municipalities from Tsuyama city. It was clarifiesd that the locational pattern of CVS corresponded to the respective population of the municipalities in Okayama Prefecture. In Okayama city, CVS were mainly located in the urban core or the surrounding area of the urban core, but they gradually expanded to the suburban areas. CVS expanded to surrounding areas of the urban core or neighboring areas of surrounding areas of the urban core. Therefore the locational pattern fo CVS differs from the tendency of suburbanization in the retail location in Okayama city. In conclucion, this analysis of the locational characteristic of CVS clarified the tendency of deversification in various areas. For example, CVS expanded to the central business district in the urban core, or to the mixed districts in the surrounding area of the urban core, or to districts that are distant from residential districts in suburban areas. However, in the analysis of the locational characteristic of closed CVS, conditions on why CVS closed down not be obtained.
