Azumaen (Unzen, Nagasaki Prefecture) Verified Reviews | Tablet Hotels

"Unzen's Azumaen draws on layers of history few Japanese resorts can match. The mountain was sacred to Shingon Buddhists from 701, then became a cosmopolitan summer escape during the Meiji era: Europeans and Shanghai expats gathered here for dance parties and rounds on Japan's first public golf course, opened 1913. The 27-room ryokan maintains gender-separated spa facilities across multiple floors, with meals served privately in rooms or dedicated dining spaces. Beyond the property lie Christian martyrdom sites and trails through the country's inaugural quasi-national park, declared in 1911, where volcanic vents still steam through ancient rock." - Tablet Hotels
