District once depended on the fishing industry, but fishing in the district has been in long decline. The district has extensive greenhouse fruit and vegetable production. The mountainous areas of Nagara, Chonan, and Mutsuzawa were once major agricultural centers, but the district's proximity to the Keiyō Industrial Zone has transformed agricultural areas into centers of small-scale industry and housing complexes. Tourism in the coastal areas has increased due to the district's proximity and rail links to the greater Tokyo Metropolitan Area. References Districts in Chiba Prefecture
