Asaba Ryokan is in Shuzenji, a quaint town located between Kyoto and Tokyo that’s home to the oldest onsen—hot springs—in the Izu Peninsula. The inn has been a fixture of the town since 1484, when the Buddhist monk Yakuro Yukitada Asaba opened it as lodging for visitors to the nearby historic Shuzenji Temple. Over the years, Asaba Ryokan morphed into a hotel for travelers of all ilks—yet, it has remained in the same family. Each room has a personal attendant who bows in and out of the sliding doors to serve tea, provide directions, and even run a bath. Expect to change into an ironed yukata (cotton robe) upon arrival. No complaints here. —Elena Clavarino
