Tlle spatial cycles hypothesis is investigated through the analytical method of ROXY index． Consideration is given to both''spatial centralization and decentralization pheno皿ena，， and '' 唐垂≠狽奄≠戟@eoncentration and deeoncentration phenomena，， of population in Japan；the former phenomena correspond to the intra－metropolitan redistribution processes of population， while the latter correspond to the inter－metropolitan redistribution processes of population． It may be laid down as a general rule that the empirical results of the study would reasonably support the basic conceptual framework of the spatial cycles hypothesis．
