A trip to the Dogo Onsen, one of Japan's most notable hot spring bathhouses, is a must for any visitor to Matsuyama. The onsen's winding hallways have been said to be inspiration for the award-winning animated film Spirited Away, and its history dates back more than a thousand years and even has a bathing room that was built especially for the emperor's use. First-timers to an onsen should read up on etiquette before arriving. Visitors can choose a few different packages--the cheapest is entry to the large public bath, while the most expensive (which is still very reasonably priced) allows for a private relaxation room after you've experienced a more exclusive bathing room. Many hotels in the area provide yukata and geta (dressing gowns and traditional sandals) to wear while exploring the area and at the onsen.
