Steam Sauna
Jet BathAbout
Tennennoyu Nagaoka is a day-use spa complex out among rice fields a few minutes from the Nankoku interchange in Kochi. The bathing side has an indoor bath with bubble-jet massage, a hexagonal open-air tub facing a dry-landscape rock garden, a waterfall-style water jet (utaseyu, うたせ湯), a cold plunge, and two saunas: a dry infrared room and a steam sauna scented with aroma oil. The spring water itself runs clear and lightly salty, smooth on the skin. Beyond the baths there is a heated 25-meter pool, a training room, a casual noodle-and-rice-bowl restaurant, and a rest area, so it works as much as a local leisure spot for a swim and a soak as it does a quiet bathhouse.
