History and Characteristics of Ikaho Hot Spring
The history of Ikaho Hot Spring is ancient, with its name appearing in the Man’yōshū and Kokin Wakashū anthologies, making it a hot spring destination known since ancient times. During the Sengoku period, under the orders of Takeda Shingen, it was developed as a recovery area for wounded soldiers, and the foundation of today’s hot spring town was established.
During the Edo period, it thrived as a therapeutic hot spring resort, and from the Meiji period onward, it became a hot spring destination beloved by literary and artistic figures. Many cultural figures such as Tokutomi Roka, Natsume Soseki, and Takehisa Yumeji visited this place, and it was depicted as the setting for their works.
The greatest characteristic of Ikaho Hot Spring is its abundant hot spring volume, among the highest in Gunma Prefecture, and the cool climate created by its high altitude. Even in summer, it remains cool and is popular as a summer retreat, with many tourists visiting year-round. Since the hot spring town spreads across sloping terrain, beautiful scenery can be viewed from anywhere, which is another of its attractions.
The Charm of Ikaho’s Symbol: Stone Steps Street
The symbol of Ikaho Hot Spring is the 365-step stone stairway. These steps were constructed with the number of days in a year in mind and serve as the main street for tourism through the center of the hot spring town.
On both sides of the steps are lined long-established inns, souvenir shops, shooting galleries, cafes, and restaurants, preserving the strong historic atmosphere of a traditional hot spring town. Shopping and eating while walking up the steps is a highlight of Ikaho sightseeing.
There are many points of interest throughout the stone steps street. Midway along the steps is a small spring outlet called “komaguci” where hot spring water is distributed to each inn. Additionally, at the top of the steps stands Ikaho Shrine, where the deity of hot springs and medicine is enshrined. It is said to bring blessings for good marriages and fertility, and many worshippers visit.
At night, the stone steps street is illuminated, creating a fantastical atmosphere different from daytime. Strolling through the stone steps in a yukata embodies the hot spring atmosphere unique to Ikaho. Benches are placed throughout the steps for resting, allowing you to enjoy your walk at your own pace.
Two Hot Springs: “Golden Water” and “Silver Water”
Ikaho Hot Spring has two different hot springs, each with distinctive therapeutic effects.
Golden Water (Kogane no Yu)
Golden Water is characterized by its tea-brown color and is the representative hot spring source of Ikaho Hot Spring. It is a sulfate spring rich in iron that turns brown when exposed to air due to oxidation. This hot spring flows beneath the stone steps and has traditionally been distributed to each inn.
The benefits of Golden Water are said to be effective for neuralgia, muscle pain, joint pain, cold sensitivity, and fatigue recovery. It is particularly popular with women and is also known as a “beauty hot spring.” After bathing, the skin becomes smooth, and the heat-retaining effect is high, making it resistant to cooling down after the bath.
Silver Water (Shirogane no Yu)
Silver Water is a transparent hot spring discovered newly in 1996. It is a simple hot spring rich in metasilicic acid and is characterized by being colorless and transparent. With less irritation than Golden Water, it is popular as a gentle hot spring on the skin.
Silver Water is said to be effective for post-illness recovery, fatigue recovery, and health promotion. In recent years, the number of facilities using Silver Water has increased, and many inns offer accommodation where you can enjoy both hot springs.
Many accommodations and day-trip facilities allow you to enjoy both hot springs, and the ability to experience the different qualities of each hot spring is one of the attractions of Ikaho Hot Spring.
