Akigami Onsen is a simple hot spring in Japan, set within a landscape that takes on its most striking character in autumn, when the surrounding hillsides turn vivid shades of red and gold in the seasonal foliage display the Japanese call koyo. The gentle alkaline waters of this simple spring are prized for their skin-softening quality and warming effect, making autumn visits—when the mountain air carries its first chill—particularly evocative and emotionally resonant. Soaking in the thermal waters while surrounded by autumn foliage represents one of the classic pleasures of the Japanese onsen experience, a ritual of seasonal attunement.
Insider tip — Akigami Onsen in the Gifu highlands lies in the mountainous Hida region near Gero — home to Gero Onsen, ranked among Japan's three greatest hot springs alongside Arima and Kusatsu. The mild springs serve a landscape of deep forested valleys in the Japanese Alps, where the Hida mountain culture, the famous Hida beef, and the abundant hot springs of the region combine in one of central Honshu's most celebrated onsen districts, near the UNESCO villages of Shirakawa-go.
