A hull resistance reduction system and a hull resistance reduction method are provided. The hull resistance reduction system is characterized in that: the hull resistance reduction system is provided with: a main engine (1), an exhaust turbine compression mechanism (20) actuated by some of the exhaust gas led from the main engine (1), and a discharge nozzle (24) for leading compressed air led from the exhaust turbine compression mechanism (20) to a submerged hull outer surface of the ship; and the exhaust turbine compression mechanism (20) is provided with an exhaust turbine (20b) rotatably driven by the led exhaust gas, a compressor (20a) that uses the rotational drive force of the exhaust turbine (20b) to compress air, and an electric power generator (21) that generates power by means of the exhaust turbine (20b) and heats the compressor (20a).
