Komatsu Onsen lies within Komatsu city in Ishikawa Prefecture, an industrial and cultural hub known internationally as the headquarters of Komatsu Ltd., one of the world's largest construction equipment manufacturers, as well as for its Kabuki theatre tradition dating back over three centuries. The sodium-bicarbonate spring water emerges at a comfortable temperature, providing smoothing, revitalising baths that have long drawn local workers and cultural travellers to this compact city between the Noto Peninsula and the mountains of Hakusan. The Komatsu Kabuki festival each spring transforms the streets with elaborate performances of traditional theatre, making the city a distinctive cultural destination that complements its thermal offerings.
Insider tip — Komatsu Onsen serves the industrial city of Komatsu at the base of the Hakusan foothills, where construction machinery manufacturing meets centuries-old bathing culture. The bicarbonate spring water rises at 40°C and is channelled into public baths that attract factory workers and tourists visiting nearby Kaga Onsen Town. The surrounding flatlands offer views of distant Hakusan volcano on clear winter days.
