Ikaho Onsen – Gunma

Overview

Ikaho Onsen is one of Japan’s most historic hot spring towns, located on the slopes of Mount Haruna in Gunma Prefecture, approximately two hours from Tokyo. With a history spanning more than 1,000 years, Ikaho Onsen is famous for its stone-step street, traditional ryokan inns, and rare iron-rich brown hot spring water.

Blending nostalgic atmosphere with natural scenery, Ikaho offers visitors a classic onsen-town experience that reflects Japan’s deep bathing culture and seasonal beauty.

Historical Background

Ikaho Onsen has been documented since ancient times and was particularly favored by:

• Samurai families during the Edo period

• Writers and poets in the Meiji and Taisho eras

The town developed as a mountain retreat where visitors could escape urban life, restore health, and enjoy nature. Many historical ryokan and cultural landmarks still preserve this atmosphere today.

The Famous Stone Steps (Ishidan-gai)

Description

The heart of Ikaho Onsen is its iconic 365 stone steps, representing the days of the year. These steps form the town’s main street, lined with:

• Traditional ryokan inns

• Small souvenir shops

• Local snack stands and cafés

Climbing the steps offers scenic views and a gradual immersion into the town’s history.

Cultural Significance

The stone steps have been the center of town life for centuries. Walking them is considered part of the Ikaho experience, connecting visitors physically and symbolically to generations of travelers before them.

Hot Spring Waters

Golden Hot Spring (Kogane-no-Yu)

Ikaho is especially known for its brownish-gold hot spring water, which contains iron. When exposed to air, the iron oxidizes, giving the water its distinctive color.

Believed benefits include:

• Improved circulation

• Relief from fatigue

• Warming the body deeply, even after bathing

This type of water is relatively rare in Japan.

Silver Hot Spring (Shirogane-no-Yu)

In addition to its famous golden water, Ikaho also offers a newer, clear hot spring source. Many ryokan provide access to both types, allowing visitors to compare their qualities.
