Sure, you can head out and explore Tenninkyo Onsen without a car. But with so much to see, having one is sure to make your trip all the more exciting. If you’re eager to venture out into some nature, consider a vehicle with some extra oomph. A full-size car or an SUV could be exactly what you need. A smaller car, like a mini or a compact, is an excellent choice for travelers heading off on shorter trips.
