Overview

Amagase Onsen boasts a history of over 1,300 years, with its existence hinted at in the "Bungo-no-kuni Fudoki," an ancient record from the Nara period. It is counted as one of the "Three Great Onsen of Bungo" along with Beppu and Yufuin, and has long been a popular destination for therapeutic bathing.

The most distinctive feature of this onsen town is the series of communal open-air baths, called "kawayu," located along the banks of the Kusu River. These baths offer an incredibly liberating experience, allowing you to feel at one with nature. Although the area suffered significant damage from torrential rains in 2020, it is gradually regaining its charm thanks to the dedicated recovery efforts of the local community. Many inns have their own private spring sources, allowing visitors to enjoy a variety of unique baths.

Key Spring Water Types and Benefits

The main spring type in Amagase Onsen is sulfur spring, recognizable by its faint egg-like aroma. This water quality is known as a "beauty spring" because it is said to soften and remove old skin cells and inhibit melanin production. You can expect your skin to feel smooth after bathing, a true "silky skin" experience. Some locations also offer gentle simple thermal springs, allowing you to choose based on your preference.

  • Atopic dermatitisThe sulfurous water is known to gently soften the skin's outer keratin layer. This action may help soothe the rough, dry patches characteristic of this condition, promoting healthier-feeling skin.
  • Psoriasis vulgaris
  • Chronic eczemaSoaking in these sulfur-rich waters can help soften and smooth the skin's surface. This may provide relief from the persistent roughness and discomfort associated with chronic eczema.
  • Impaired glucose tolerance (Diabetes)
  • Cuts
  • Poor circulation
  • Dry skin

Water Characteristics and Best Seasons

The source temperature is very high, ranging from 80 to 100°C (176-212°F), with an abundant flow of water. As a result, many inns and public baths cool the free-flowing spring water to a comfortable temperature by adding river or stream water. The best seasons to enjoy the rustic riverside baths are spring, with its fresh green foliage, and autumn, when the area is enveloped in vibrant fall colors. In winter, you may even have the special experience of bathing while admiring a snowy landscape.
