A frictional resistance reducing method for ships, and a ship with reduced frictional resistance, which are intended to reduce the power required to send a gas into water and effectively reduce the power required during the navigating of the ship and to save the construction cost of ships. A negative pressure location (21) which is reduced in pressure relative to a gas space as the ship navigates is defined in water, and the gas is led from the gas space into the negative pressure location (21) in water, emitting bubbles (22) into water.
