A vehicle approach notification system for notifying approach of a vehicle includes: a first speaker and a second speaker provided in a speaker case included in a vehicle; a sound source that outputs sound signals which are respectively input to the first speaker and the second speaker and correspond to a sound notifying the approach of the vehicle; and a phase controller that controls a phase of at least one sound signal out of the sound signal input to the first speaker and the sound signal input to the second speaker so that sound pressure at left and right of the vehicle caused by the sound output from the first speaker and the second speaker is higher than sound pressure along a longitudinal axis of the vehicle caused by the sound output from the first speaker and the second speaker.
