Located in Gunma Prefecture, Ikaho Onsen is one of Japan’s most historic and picturesque hot spring resorts. Surrounded by scenic nature and steeped in tradition, it offers visitors a truly authentic Japanese experience. In this guide, you’ll find essential information on how to get there, top attractions, and seasonal highlights—everything you need to plan the perfect trip.
Ikaho Onsen is nestled in the city of Shibukawa in Gunma Prefecture and has been beloved by locals and travelers for centuries. Its origins are thought to date as far back as the 1st century BCE, with another theory attributing its discovery to the Buddhist monk Gyoki in the 8th century, who is credited with spreading Buddhism in Japan. The hot spring is even mentioned in literature from the Nanbokucho period (14th century), showing its long-standing reputation as a healing retreat.
One of its most iconic features is the “Golden Water” (Kogane-no-Yu)—a reddish-brown spring rich in iron content that oxidizes when exposed to air. This mineral-rich water is not only visually striking but also gentle on the skin, making it a favorite for therapeutic bathing.
Ikaho Onsen also has deep ties to Japanese culture and the arts, having inspired numerous writers and painters who visited for both leisure and inspiration.
Getting to Ikaho Onsen is simple and convenient, especially from Tokyo. From Tokyo Station, take the Joetsu or Hokuriku Shinkansen to Takasaki Station, then transfer to a local bus for about an hour to reach Ikaho. For international travelers, there’s also a direct highway bus from Narita Airport, which takes approximately three hours, making it easy to head straight to the hot springs after landing in Japan. Once you arrive, you’ll find that the onsen town is compact and walkable, perfect for leisurely exploring on foot while soaking in the atmosphere of a traditional Japanese hot spring resort.
Here are five carefully selected spots that you won’t want to miss during your visit to Ikaho Onsen.
