Sure, it’s possible to head out and explore Iwamuro Onsen without a car. But with so much to see and do, having one is sure to make your trip all the more memorable. If you’re excited to venture out into nature, choose something with some extra oomph. A full-size car or an SUV will do the job in style. A smaller car, like a mini or a compact, is a great choice for travelers heading off on shorter trips.
