Overview
Kawaji Onsen was discovered in 1718 during the Edo period. Legend says that after a period of long rain caused a river to flood, hot spring water was found gushing from the riverbank. It flourished as a post town and therapeutic spa on the Aizu Nishi Kaido, an important route connecting Nikko and Aizu-Wakamatsu, offering rest to many travelers.
An old saying, "Go to Kawaji for wounds, and Taki (present-day Kinugawa Onsen) for burns," highlights its reputation for healing injuries. Today, its gentle spring water and the tranquil environment of the beautiful valley continue to attract visitors seeking both physical and mental relaxation.
Primary Spring Quality and Indications
The main spring type at Kawaji Onsen is a "Simple Onsen" (Tanjun Onsen), which is mild and gentle on the skin. The water is clear, odorless, and slightly alkaline, which can help to smooth the skin. It is suitable for everyone, from babies to the elderly.

Water Characteristics and Best Season
The source temperatures range from 40 to 60°C (104-140°F). Many establishments offer high-quality, free-flowing spring water directly from the source without adding cold water or reheating. Numerous ryokans are located along the valley, and their open-air baths (rotenburo) with the sound of the flowing river offer an exceptional experience.
While the area's natural beauty can be enjoyed year-round, the autumn season is particularly spectacular, with the entire valley painted in vibrant reds and yellows. A winter visit also offers the charming experience of a "yukimi-buro" (snow-viewing bath).
