Ritomaru Co., Ltd. (headquartered in Iki City, Nagasaki Prefecture, CEO: Hiroyuki Okumura) will soft open a new accommodation facility, "THE RIHAN South Aso Mizu no Oyado" in Minami-Aso on Monday, September 8, 2025.
A Perfect Harmony of Land and Water in Minami-Aso
Stay nestled alongside the blessings of the great land and water of Minami-Aso.
This facility is a special place where a traditional farmhouse, breathing with the nature and culture of Minami-Aso, has been revitalized with contemporary sensibilities.
Respecting the way of life and history that have been passed down in this land, it offers a lodging experience that connects the past and future. For reservations and details, please visit the official website (https://ritomaru.co.jp/minamiaso/).
*According to company research (as of August 2025)
"THE RIHAN South Aso Mizu no Oyado" is the result of carefully renovating a historic farmhouse built over 150 years ago, creating a space that fuses its charming appearance with modern comfort.
From the accommodation, guests can enjoy panoramic views of the majestic Aso Five Peaks and the ridgeline of the outer rim mountains, while at night, a canopy of stars spreads across the sky.
Just nearby flows a stream from the outer rim mountains. Listening to the sound of flowing water while gazing at the peaceful mountain scenery and the appearance of traditional houses brings exceptional tranquility.
The area where this facility is located in Minami-Aso features diverse tourist spots, including the "Shirakawa Spring" selected as one of Japan's 100 best waters, "Kusasenrigahama" offering views of the Aso Five Peaks, the mystical "Kamishikimi Kumanoza Shrine," and the "Trolley Train" of the Minami-Aso Railway.
Additionally, activities such as horseback riding and trekking are abundant, and guests can enjoy seasonal nature experiences, including strawberry picking in spring.
Private SPA for Premium Relaxation
The facility features a sophisticated relaxation area with a semi-outdoor bath overlooking the Aso Five Peaks where guests can relax in a lying bath. The sauna is also designed for lying down in comfort. The water bath, with particular attention to water depth, stimulates blood vessels and cells with adequate water pressure, enhancing the sense of release after bathing. The contrast between hot and cold promotes circulation, allowing for deeper physical and mental refreshment.
Amenities include products from the New York-based fragrance brand "Le Labo." Enjoy a truly special time.
Furthermore, treatment menus including oil treatments, bodywork, and yoga are available through partner therapists.
Throughout your stay, you can deepen the harmony of mind and body even further.
Exclusive Views of the Majestic Aso Five Peaks and Starry Skies
The second floor of the accommodation features an open space that takes advantage of traditional roof framing.
From here, guests can enjoy panoramic views of the majestic Aso Five Peaks mountain range and a sky full of stars. In the morning, enjoy the spectacular views with aromatic coffee brewed with well water.
