'OYUGIWA Niiza Onsen,' opening in Niiza City, Saitama, is a new relaxing hot spring destination where multiple generations, from children to seniors, can enjoy themselves all day. It was born from a strong desire to create a new place in Niiza City where multi-generational families can forget their daily lives and relax from the heart.

■ Past Engagement between OYUGIWA and Local Communities
OYUGIWA holds the 'Kids Staff in OYUGIWA' vocational experience event for local elementary school students every summer vacation. Children explore the 'backstage' of the bathhouse, assist with tasks such as hot water management and cleaning, and take on the challenge of being a 'thermal wave master' using the large fans famous at the facility for 'Roryu.' It is an event that teaches children the joy of working along with learning not available at school.
Additionally, through 'Plogging de Hito-Puro,' we support activities that pick up trash while jogging in the area and provide a place for participants to refresh themselves afterward.
