Sure, you can do Iwakuni without renting a car. But with loads to see and experience here, having one would certainly make your stay more comfortable. If you plan to head out of town and into the countryside, pick a vehicle with some power. A larger car like an SUV will take you to the area’s bays in style. Rather spend the majority of your time right in the city? An economical, small car is a wise choice. Maneuvering around busy streets and squeezing into tiny parking spaces will be a piece of cake with one of these.
