Overview
The history of Ikaho Onsen is ancient, with mentions in the Man'yoshu, Japan's oldest poetry anthology. The iconic stone staircase, the town's centerpiece, is said to have been established in 1576 during the Warring States period, making it a pioneering example of Japanese hot spring town planning. The 365 steps are lined with ryokans, souvenir shops, and eateries, creating a charming atmosphere perfect for a stroll in a yukata.
Ikaho's most notable feature is its two types of spring water. The original "Kogane no Yu" is rich in iron, turning a distinct brownish-red color upon contact with air. It's known for its ability to warm the body to the core. In contrast, the more recently discovered "Shirogane no Yu" is clear and gentle on the skin, said to be beneficial for recuperation and general health.
Key Spring Qualities and Indications
Ikaho Onsen offers two main spring types. "Kogane no Yu" is a Calcium/Sodium - Sulfate/Bicarbonate/Chloride spring, classified as both a "Sulfate spring" and an "Iron-containing spring." "Shirogane no Yu" is a "Simple thermal spring" containing metasilicic acid. Kogane no Yu is particularly known for its long-lasting warming effect.

Water Characteristics and Best Season
The source temperature of "Kogane no Yu" is around 45°C, with a plentiful flow of about 4,000 liters per minute, allowing many facilities to offer free-flowing hot spring baths (gensen kakenagashi). "Shirogane no Yu" has a smaller flow and is often used in circulating systems. While Ikaho is a year-round destination, it is especially popular in autumn (late Oct to mid-Nov) when the Kajika Bridge, a famous foliage spot, is illuminated. The winter snowscape also offers a special beauty.
