Onsen & Spa Services
Release your mind,
embraced by the gentle country breezes,
and the soft babbling of the Otozure River
The hot springs of Nagato Yumoto Onsen have been flowing since 1427, in the Muromachi Period.
Take in the scent of the trees carried on the breeze, the sound of flowing water, and soft birdsong.
The large public bath looks out over the flowing waters of the Otozure River, creating a view reminiscient of traditional Japanese "sansui" landscape paintings.
Immerse yourself in the soothing embrace of the soft, alkaline waters, known as a "family bath," because they are gentle enough for those of all ages, from babies to the elderly.
