Overview
The history of Amagase Onsen is ancient, with mentions in the "Bungo-no-kuni Fudoki," a provincial record compiled in the Nara period (8th century). Even after more than 1,300 years, hot water continues to gush from the banks of the Kusu River. During the Edo period, it also flourished as a post town for feudal lords traveling for their sankin-kotai duties.
The main attraction of this onsen town is the five public open-air baths dotted along the Kusu riverbed. These baths, called "kawayu," use natural rocks as tubs, and soaking in them while listening to the river's murmur is an exceptional experience. In recent years, wearing bathing attire has been encouraged, making this rustic experience accessible to everyone.
Main Mineral Springs and Health Benefits
The primary spring type in Amagase Onsen is the Sulfur Spring, characterized by a faint sulfurous aroma. Some sources are classified as Simple Thermal Springs. Sulfur springs are known as "bihada-no-yu" (beauty springs) as they are said to help soften the skin's keratin and break down melanin, which can cause spots and dullness.

Water Characteristics and Best Season to Visit
The source temperatures are extremely high, ranging from 80°C to nearly 100°C (176-212°F), so most facilities add cool water to regulate the temperature. However, thanks to the abundant water volume, most ryokans offer fresh, free-flowing spring water (gensen kakenagashi). The water has a slightly thick texture and is gentle on the skin.
To best enjoy the riverside open-air baths, the mild climates of spring and autumn are ideal. The valley is adorned with cherry blossoms in spring and colorful foliage in autumn, creating a beautiful backdrop for bathing. Soaking in the onsen while viewing a snowy landscape in winter is also a charming experience.
