The purpose of the present invention is to provide a technology which enables scent control. Provided is a scent presentation module comprising: a first opening part through which a first air flow containing a scent exits; and a second opening part through which a second air flow exits. The first opening part and the second opening part are provided so that movement of the first air flow that has exited from the first opening part can be controlled by the second air flow. Also provided are a scent presentation device comprising the scent presentation module, and a scent presentation system. Further provided is a scent presentation method comprising: a first air flow generation step in which a first air flow containing a scent is output from a first opening part; and a second air flow generation step in which a second air flow that exits from a second opening part or a second air flow that enters a second opening part is generated. The movement of the first air flow that has exited from the first opening part is controlled by the second air flow.
