What is Ikaho Onsen (伊香保温泉) ?
Charming attractions in the past and present
Ikaho Onsen has long been known as a famous hot spring. The hot spring resort is located on Mount Haruna, about 700 meters above sea level in Gunma Prefecture.
During the Edo period (1603-1868), travel to Ikaho Onsen was so booming that a Sekisho (checkpoint) was built in response to the increase in the number of visitors to the hot-spring. After the Meiji era (1868-1912), the place was also loved by many cultural figures.
It takes only 1 hour and 20 minutes from central Tokyo by car on the expressway, making it popular for visitors to enjoy a casual trip to the hot springs.
Two types of hot water gushing out
At Ikaho Onsen, visitors can enjoy two types of hot springs: Kogane-no-yu(Golden hot water), a brownish-brown water that has been gushing out since ancient times, and “Shirogane-no-yu,(White silver water)” a colorless, clear water that was discovered in recent years. Not only the color of the water but also its efficacy differs, and being able to enjoy two different types of hot springs in the same area is a feature unique to Ikaho Onsen.
There are many other ways to enjoy besides hot springs
The stone stairway streets that has become a symbol of Ikaho is said to be the first in Japan to be built according to a hot spring resort plan, and visitors can enjoy walking around the town while feeling the history and the emotional atmosphere of the hot spring resort. In addition to the hot springs, Ikaho Onsen offers a wide variety of tourist attractions such as historical sites, leisure facilities, and museums in the neighborhood, as well as seasonal fruit picking and local delicacies.
There’s a view you can only see there
In winter, the minimum temperature can drop below freezing, and the roads can become icy and snowy. In summer, the average temperature in August exceeds 30°C (86°F), typical of inland areas with a wide range of temperatures throughout the year.
Surrounded by rich nature and high mountains, visitors can enjoy cherry blossoms in spring, mountain azaleas with vivid red colors that cannot be seen in the city, alpine flowers, and the changing seasonal scenery of fresh green, autumn leaves, and snow on the mountains.
Highlights of a trip to Ikaho Onsen
Enjoy two types of hot water
The hot spring is said to have gushed out due to the volcanic activity of Mt. Haruna Futatsudake during the Kofun Period (250 – 538), and at Ikaho Onsen, which has a long history, visitors can enjoy two types of hot spring water Kogane-no-yu(Golden hot water), which has a unique brownish color, and Shirogane-no-yu(White silver water), which is clear and colorless.
Originally, only Golden hot water, in which the iron contained in the hot water was oxidized by exposure to the air and turned brownish brown, gushed out. Because the water was soft on the skin with little irritation, many people came to visit Ikaho to recuperate from illness or injury or for rest and relaxation.
It is also particularly popular with women as it warms the body from the core and promotes blood circulation, and has been popular since the Edo period.
And “Shirogane-no-yu(White silver water)” boasts an abundance of 110 liters of hot water per minute, and its gush has been confirmed in recent years. It was named so because it was colorless and transparent. It is said to be good for relieving fatigue, improving health, and recovering from illness.
At Ikaho Onsen, you can enjoy either one or both hot springs at each lodging facility or day spa. Enjoy the hot springs according to your preferences and travel plans.
Walking along the stone steps of the town
Ishidan gai(The stone steps streets), the main street of Ikaho Onsen, has 365 long stone stairs leading up to the Ikaho Shrine, and is lined on both sides with onsen ryokan, amusement facilities for shooting gallery, and souvenir shops. The stone steps are perfect for a leisurely stroll up the street and feel the atmosphere of a hot spring.
The history of the stone steps streets is very old, and it is said to have been created around 1576 during the Sengoku period. Stone steps were built, and hot spring water was newly drawn, and the area began to be managed as a hot spring resort.
The current stone steps, renovated over a five-year period starting in 1980, are paved with granite—a stone formed by the cooling of magma at depth and pressure from above ground. The poem “Town of Ikaho” by the poet Akiko Yosano is inscribed in the middle of the stone steps.
In 2010, the stone stairway was extended further to the north to 365 steps, with the hope that the Ikaho Onsen will be lively with people 365 days a year. A hot spring waterfall and a plaza were also built in the center of the stairway. Stone stairs markers are placed at the 100th, 200th, and 300th steps, as well as at the 365th step.
You can also find signs of the twelve zodiac signs along the stone steps. More than 200 years ago, there were 12 hot spring inns called “Oya” in this area, and since the zodiac signs had a meaning like the family crest of each inn, they decided to mark the stone steps where the inns were located with the signs of the 12 zodiac signs. Please take a stroll along the stone steps and find your own zodiac sign.
It is also popular to take a photo at your birthday or anniversary number of the steps. There are websites where you can check the number of steps for your birthday or download a commemorative step certificate. You can check them in advance and add them to your travel plans!

Enjoy nature in each of the four seasons
Ikaho Onsen is a hot spring resort that developed on the slopes of Mount Haruna at an elevation of around 700 meters, and is surrounded by high mountains. Being surrounded by nature, visitors can enjoy the flowers and scenery of the four seasons close at hand.
In spring, visitors can enjoy viewing cherry blossoms at Shibukawa City Park and Ikaho Green Bokujo (farm), and from late April to early May, approximately 1,500 peonies are at their best on the grounds of Shorenji Temple in Shibukawa City.

Discover the history of Ikaho Onsen
There are two theories about Ikaho Hot Spring. One says that it was opened during the reign of the 11th Emperor Suinin, and the other says that it was discovered during the Tenpyo Period (729-749) by the monk Gyoki, just like the Kusatsu Hot Spring in Gunma Prefecture. Although various theories exist, it is said that a book written during the Nanbokucho Period (1336-1392) mentions the presence of a hot spring already gushing out, indicating its long-standing existence.
During the Manyo period, the area around present-day Mt. Haruna was called Ikaho, and many poems were composed about the area. The Manyoshu, said to be Japan’s oldest anthology of poetry, contains nine poems about Ikaho, giving visitors a sense of the area’s history.
The stone staircase that is the symbol of Ikaho Onsen is said to have been built in 1576 by Kogure Shimousa no Kami Suketoshi, who was under the control of the Uesugi and Takeda clans during the Sengoku period, to treat the wounded warriors of the Takeda clan during the Battle of Nagashino. A monument stands halfway up the stone stairway, which is said to be Japan’s first hot spring resort.
As travel became more popular in the Edo period, the hot-spring cures at Ikaho Onsen became popular, attracting people from all over the country. As the number of travelers increased and the area was also an important transportation hub, a guard station was set up here to control the flow of traffic. Today, it is restored as the Ikaho Sekisho and can be visited.
And during the Meiji period (1868-1912), the Villa was also built and became a bustling summer resort for political and financial figures, literary figures, and foreigners from the central part of Japan.
In addition, Yokote-kan, a hot spring ryokan located on the stone step street, still retains its Taisho era wooden structure, which still retains the atmosphere of that time.

Local Food of Ikaho Onsen
Mizusawa udon (水沢うどん)
Mizusawa udon is said to be one of the three best udon noodles in Japan and is famous throughout the country for its firm texture. It is said that the origin of this local delicacy dates back several hundred years, when udon noodles were made and served to visitors to the Mizusawa Kannon shrine near Ikaho Onsen, using wheat grown in Joshu and spring water from Mount Mizusawa.
The area in front of the gate of Mizusawa Kannon is also known as “Mizusawa Udon Kaido(road),” and is lined with stores specializing in Mizusawa udon. From long-established stores that have been in business for several hundred years to newer establishments, each store competes with the others to offer the best taste of its specialty. Mizusawa udon is usually served cold udon (eat cold udon with cold soup), but most stores also serve kake udon (udon served in warm soup). You can compare udon noodles from different stores.
Founded in 1970, Osawaya has two stores on the Mizusawa Udon Road. The freshly made udon noodles have the original flavor and chewy texture of wheat flour. They are particular about serving cold Zaru Udon and have heated floors so that cold udon can be enjoyed even in winter. The soup is handmade by artisans every morning. Maitake mushroom tempura grown by a local contract farmer is also highly recommended.
Yunohana Manju (湯の花まんじゅう)
Ikaho Onsen is renowned as the birthplace of onsen manju, a thin-skinned brown bun commonly found in hot spring resorts across Japan. Stores selling onsen manju, known as “yunohana manju,” line the stone stairway and the prefectural road.
Shougetsu-do, founded in 1910 and located below the Ikaho Onsen, is the store where it originated. The hot water of the Ikaho Onsen is brown in color due to its high iron content, so much so that tenugui (hand towels) are dyed brown. Inspired by the color of the hot spring water in Ikaho, the founder of Shougetsu-do made brown manju with brown sugar and sold it as a souvenir of the Ikaho onsen.
The brown outer is soft, and the rich red bean paste is made from azuki beans grown in Tokachi, Hokkaido, and has a pleasant texture and elegant sweetness. The ingredients are additive-free and handmade by artisans every day using a method that has remained unchanged for 100 years.
