Yamakawa Onsen Kosugi-an is nestled in the rich natural landscape of Aso, Kumamoto.
This area, historically known as “Higo-Oguni,” has deep cultural roots in the old Higo Province.
Here, you can experience the beauty of Japan’s four seasons and enjoy moments of true relaxation.
In our garden, you will find seasonal trees such as cherry blossoms in spring and colorful maple leaves in autumn, along with a gently flowing river.
It creates a peaceful space where you can feel as if you are one with nature.
We invite you to enjoy a special experience that can only be found here.
We offer four different baths, each with its own unique atmosphere.
Our natural hot spring water flows directly from the source, gently relaxing both your body and mind and guiding you into deep comfort.
We hope you will fully experience the charm of this special place.
At Yamakawa Onsen Kosugi-an, we warmly welcome guests every day.
Please enjoy a luxurious stay surrounded by the beautiful nature of Higo-Oguni.
Majestic peaks stand serenely,Watching over time itself.
In the silence,
The wind gently stirs a melody of green.
A soothing moment,Where the murmuring stream
weaves its melody.
