nikissimo Spa

Phytotherapy in the forest

nikissimo Spa

Inside is a treasure garden with little animals like squirrels and rabbits, as well as rare species of wild flowers.
Spring water rushes and the Futa-ai river, a clear mountain stream, flows past.

NIKI Club & Spa is a resort fusing the nature and has been gradually created over the last 26 years. “Aroma Therapy Salon nikissimo” at NIKI CLUB & Spa offers a variety of programs to maintain your body and mind holistically following the idea of naturopathy (phytotherapy), which makes use of the natural healing power of plants.

Step away from hustle and bustle of daily life and take a walk in the forest. Warm up your body by bathing in a hot spring which brings the power of the Earth and feel the wind as it brushes the trees. Relax your body deeply with long, languid treatment.
Health, Mind, Spirit, Beauty – NIKI CLUB & Spa’s “Well-Being Spa Journey” begins as you bathe in the forest, soak in a hot spring, enjoy a treatment and select from our spa menu with plenty of seasonal herbs.

Forest Stroll – Experience NIKI’s forest with our Forest Concierge

This strolling program is available early in the morning.
Breathe deep and bring fresh air into your body, and enjoy forest bathing in all four seasons in the beautiful Nasu district.


The hot spring source contains naturally occurring sulfur, calcium, magnesium sulfate and hydrogen carbonate. This clear, colorless water is effective for recovering from fatigue, muscle pain and neuralgia.
Try our open-air hot spring in the forest.
*Spa is closed from 11:00 through 15:00 for cleaning.
