1. A driving assistance device comprising:
a storage device configured to store a program; and
a processor connected to the storage device,
wherein the processor executes the program stored in the storage device to:
acquire information about a target position decided on as a position relative to another moving object located in a second lane when a host moving object merges or changes lanes from a first lane to the second lane; and
cause a speaker to output a sound obtained by combining a basic sound for acceleration guidance with an additional sound for the acceleration guidance having a higher frequency than the basic sound for the acceleration guidance when the host moving object should accelerate such that position alignment related to a traveling direction of the host moving object is performed with respect to the target position,
wherein the additional sound for the acceleration guidance includes a plurality of sounds having frequencies different from each other.
