"Set in a 17th-century building on the verdant slopes of Hakone, Japan, Matsuzakaya Honten is the absolute gold standard for onsen hospitality. The timeless luxury of their private hot springs hardly needs introduction and is available in both communal and private settings. Meiji period details abound in public spaces, including a lounge, bar, and unique sunken hearth area. Rooms overlook enchanting, mossy gardens and feature mountain views, cozy tatami, and gorgeous natural wood." - Tablet Hotels
