Abstract: A vehicle proximity notification device that notifies proximity of a vehicle by causing a speaker disposed outside a vehicle interior of the vehicle to output a warning sound. The vehicle proximity notification device includes: a controller that, when a sound pressure of a sound collected by a microphone disposed outside the vehicle interior exceeds a first threshold, sets a sound pressure of the warning sound output by the speaker to a level lower than the sound pressure of the warning sound output by the speaker when the sound pressure of the sound collected by the microphone is lower than or equal to the first threshold.
