Japan's chemical industry evolved from wartime military chemistry and fertilizer production, forming a deep industrial layer of zaibatsu-affiliated and independent companies including Mitsui Chemicals, Sumitomo Chemical, Mitsubishi Chemical, Shin-Etsu Chemical, and Asahi Kasei. Petrochemical complexes were built as national policy in the late 1950s but suffered chronic overcapacity after the oil shocks. Industry consolidation accelerated from the 2000s, producing Mitsubishi Chemical through merger. Shin-Etsu Chemical holds the global top position in both PVC resin and semiconductor silicon wafers, synonymous with high profitability. In pulp and paper, Oji and Nippon Paper dominate but face declining demand from digitization. In plant engineering, JGC and Chiyoda Corporation have world-class track records in LNG plant construction.
