Overview
The discovery of Oigami Onsen is deeply connected to a legend of a battle between the serpent god of Mt. Akagi and the centipede god of Mt. Nikko-Futarasan. The story goes that the wounded Akagi god, while retreating, pulled an arrow from his body, and a hot spring gushed forth from the spot. The name is said to have evolved from "Oigami" (追い神), meaning "the place where the god was driven away," to its current characters (老神), which mean "old god."
The onsen village is situated along the deep Katashina Gorge, a tributary of the Tone River, with over a dozen ryokans and hotels. Surrounded by lush nature, it offers a tranquil environment to forget daily life and soak in the baths. The Oja Matsuri (Great Serpent Festival) in mid-May, featuring a giant serpent float parading through the town, celebrates this legend and attracts many visitors.

The water is characteristically soft, colorless, and transparent with low irritation, earning it the name "Bijin-no-yu" (water of beauty). It's known for leaving the skin smooth and is believed to be effective for skin conditions.

Water Characteristics and Best Seasons to Visit
The source temperatures are relatively high, ranging from 50-65°C (122-149°F), but are adjusted to a comfortable bathing temperature at each facility. Many ryokans feature gensen kakenagashi baths, where abundant, fresh spring water flows freely. The numerous open-air baths (rotenburo) overlooking the gorge offer an exceptional experience, allowing you to feel the changing seasons.
The best times to visit are in spring (May-June) for the vibrant green foliage and in autumn (late October-mid November) when the gorge is ablaze with red and yellow leaves. Winter offers a serene experience, enjoying the onsen amidst a snowy landscape, making it a destination with year-round appeal.
