1. A driving assistance device that assists driving of a vehicle, the driving assistance device comprising:
a first detector configured to detect a driver's accelerator operation on an accelerator operator provided in the vehicle;
a second detector configured to detect a driver's brake operation on a brake operator provided in the vehicle;
a third detector configured to detect a surrounding situation of the vehicle;
a notification unit configured to perform notification for recognition of a risk associated with traveling of the vehicle present in the surrounding situation detected by the third detector to a driver of the vehicle;
a determination unit configured to determine a degree of recognition of the risk by the driver based on a period of time from when the first detector no longer detects the accelerator operation to when the second detector detects the brake operation in response to the risk present in the surrounding situation detected by the third detector; and
a control unit configured to control the notification unit so that the notification according to the degree of recognition determined by the determination unit is performed,
wherein when an operation amount of the accelerator operator corresponding to the accelerator operation detected by the first detector in response to the risk present in the surrounding situation detected by the third detector is equal to or less than a predetermined operation amount, the control unit controls the notification unit so that a timing of starting the notification is earlier than a reference timing.
