Matsumoto Jūjō

Every room at this ryokan-adjacent retreat in Asama Onsen comes with its own private spring-fed bath, which freed up the old communal soaking hall to become a restaurant, café, bakery, bookshop, and shop. The bones of the original inn, an old-school fixture of this resort town, survived the redesign even if what stands now looks quietly modern. The name translates loosely as "ten stories," referring to chapters of history rather than floors.
