1. A driving assistance device comprising:
a storage device storing a program; and
a hardware processor connected to the storage device,
wherein the hardware processor reads and executes the program stored in the storage device to:
recognize a risky physical object located near a mobile object on the basis of an output of a physical object detection device,
cause at least one speaker to output a notification sound on the basis of a position of the risky physical object, and
when the notification sound is output, cause the at least one speaker to output a first notification sound if the risky physical object is located in a first region including a region in front of the mobile object and cause the at least one speaker to output a second notification sound if the risky physical object is located in a second region including a region behind the mobile object, and
wherein the first notification sound is a sound having a pitch different from that of the second notification sound,
the first notification sound includes a first fundamental sound and a first additional sound, and
the hardware processor changes a mode of the first additional sound on the basis of a position of the risky physical object within the first region when the risky physical object is located in the first region.
