About Aridagawa Onsen Hikari no Yu

"Aridagawa Onsen Hikari no Yu" is a hot spring facility in Arida, Wakayama Prefecture. Its natural sodium chloride spring has excellent heat-retaining properties. Alternating between the 41-degree hot spring and the 28-degree cold spring helps regulate the autonomic nervous system and boost metabolism. The hot spring sauna, which vaporizes the source water, and the high-temperature sauna lined with Kishu binchotan charcoal deeply warm the body, while the cold plunge bath using groundwater from the Aridagawa River cools you down refreshingly. There are also an outdoor rock bath, a walking bath, and tsuboyu. At the restaurant "Mansai," you can enjoy local swordfish dishes and fresh seafood, and the comic corner with more than 4,000 volumes lets you relax after bathing.

Hot SpringONSEN

Free-flow from source

Aridagawa Onsen

A sodium chloride spring that bubbles up from underground. Commonly called the "hot water of heat," its salt content forms a thin film on the skin, so its moisturizing and heat-retaining effects last for a long time even after you get out of the bath. The water feels smooth, with such a rich mineral content that you can taste the saltiness. It warms you deeply from the core, and is expected to help relieve sensitivity to cold, muscle pain, and joint pain. In the large public bath, you can enjoy alternating baths between the 41-degree hot spring and the 28-degree cold spring source water, experiencing a unique bathing method that stimulates the autonomic nervous system and promotes metabolism.

SaunaSAUNA

01SAUNA

Kishu Binchotan Charcoal Sauna

Men's

A high-temperature sauna with walls covered from floor to ceiling in Kishu binchotan charcoal. Thanks to the far-infrared effects of binchotan, the body warms evenly from the core. The men's sauna is equipped with an automatic löyly feature that operates every 7 minutes, periodically spreading steam throughout the room and sending waves of heat across the body. The soft, deep heat unique to binchotan gradually penetrates the whole body and induces abundant sweating. It is easy to breathe in and comfortable for everyone from beginners to advanced sauna-goers. Its appeal lies in the wholesome thermal environment created by natural materials.

02SAUNA

Hot Spring Sauna

Men's

A world-first hot spring sauna that uses "heated water vapor" made by vaporizing source water. Mist derived from the spring fills the room, and with every breath, the hot spring components soak into the body through the skin and lungs. The steam gently wraps the skin and slowly encourages perspiration. It offers a rare experience of taking in the benefits of sodium chloride spring water from both inside and out. The high humidity makes it comfortable to stay for long periods without worrying about dry skin. This is a one-of-a-kind bathing style where you can soak your whole body in hot spring components.

Aridagawa Natural Groundwater

Men's

A cold plunge bath using groundwater from the clear Aridagawa River. The naturally springing groundwater feels soft and smooth on the skin and has a clean, refreshing quality with no chlorine smell. It gently envelops a body warmed by the sauna while cooling it effectively. The excellent water quality stands out, and it is comfortable enough to soak in for a long time without irritating the skin.
