Enakyo SA (Osaka-bound) serves as an excellent rest area 1.5 hours from Kamisuwa Onsen, convenient for facilities breaks. Ena City's historical significance as the former Nakasendo highway post town Oi-juku is reflected in the SA's thoughtful architectural design. The building successfully recreates the atmosphere of traditional Japanese traveler inns through warm wooden construction that feels authentic and period-appropriate. The observation deck offers sweeping views of Gifu's mountain ranges and the majestic Mount Ontake beyond. A popular Starbucks location allows visitors to enjoy coffee while relaxing comfortably. This location provides a genuinely restorative experience that beautifully combines historical atmosphere with natural splendor.
