1. A parking assist device that assists in performing an operation of parking a vehicle, the parking assist device comprising:
a memory; and
a processor that is communicatively coupled to the memory,
wherein the processor is configured to:
calculate and update a parking-allowing location, that being a space where the vehicle can be parked, a plurality of times before the vehicle stops at the parking-allowing location,
calculate a parking route leading from a current location of the vehicle to the parking-allowing location, wherein
the processor sets a minimum turning radius for calculating the parking route, based on an amount of a shift between the parking-allowing location not updated and the parking-allowing location having been updated and on an amount of a shift of the vehicle from the parking route, and calculates the parking route using the minimum turning radius, and wherein
the minimum turning radius is set to be larger than a minimum value of a turning radius unique to the vehicle.
