Geography and Natural Environment
A City Near the Center of Japan
Shibukawa is considered to be located close to the geographical center of the Japanese archipelago, excluding Okinawa. For this reason, it is widely known as one of the places associated with the “Navel of Japan.”
In 1984, Shibukawa declared itself the “Navel City in the Center of Japan” and has also hosted the National Navel Summit, a gathering associated with communities across Japan that identify with the concept of the country’s geographical center.
Mountains, Rivers, and Rich Landscapes
The foothills of Mount Haruna extend across the western part of the city, while Mount Akagi rises to the east. To the north are Mount Komochi and Mount Onoko.
The city is also blessed with abundant water. The Tone River flows from the north, while the Agatsuma River flows from the west before the two rivers meet in the Shiroi area.
Although Shibukawa’s urban area is relatively compact—approximately 6 kilometers from east to west and 10 kilometers from north to south—the city contains a remarkable variety of mountains, rivers, forests, hot spring landscapes, and rural scenery.
The Many Attractions of Shibukawa, the “Navel of Japan”
Shibukawa has prospered as a transportation hub since ancient times, and today its major industries include tourism, manufacturing, and agriculture. Above all, the famous Ikaho Onsen has attracted visitors seeking relaxation and healing for centuries.
However, the appeal of Shibukawa extends far beyond its hot springs. Visitors can enjoy changing seasonal scenery, historic sites, museums, traditional festivals, cultural events, and food made with local agricultural products.
The city can broadly be divided into six areas, each with its own character and attractions.
Ikaho Area – Famous Hot Springs and Traditional Resort Atmosphere
The Ikaho area is the center of tourism in Shibukawa and is home to the internationally recognized hot spring resort of Ikaho Onsen.
The hot springs have an exceptionally long history and are even mentioned in the Manyoshu, Japan’s oldest major anthology of poetry. For centuries, people have visited Ikaho to relax and enjoy the therapeutic atmosphere of the mountains.
Ikaho Onsen’s Two Famous Springs
Ikaho Onsen is traditionally associated with two types of hot spring water: “Kogane-no-Yu,” or Golden Hot Spring, and “Shirogane-no-Yu,” or Silver Hot Spring.
Kogane-no-Yu contains a relatively high amount of iron, giving the water its distinctive brownish color. The warm, gentle water has long been associated with bathing for relaxation and is traditionally known as a hot spring for supporting fertility and women’s health.
Shirogane-no-Yu is a comparatively newer source. It is clear and relatively mild, with a plentiful supply of water. It is traditionally regarded as suitable for recuperation, relieving fatigue, and maintaining good health.
Ikaho Stone Steps
The Ikaho Stone Steps are the symbolic heart of the hot spring town. Along with Yamadera in Yamagata Prefecture and the approach to Kotohira-gu Shrine in Kagawa Prefecture, the street is often counted among Japan’s famous historic stairways.
The stone staircase is said to have been developed approximately 440 years ago as part of an early planned hot spring town. Today, it serves as the main street through Ikaho, with traditional inns, souvenir shops, restaurants, and shooting galleries lining both sides.
Walking up the steps is one of the best ways to experience the atmosphere of Ikaho. During the day, the street is lively with visitors, while at night, lanterns and other lights create a more atmospheric setting.
Kajika Bridge and the Colors of the Seasons
Kajika Bridge is a striking vermilion-painted bridge located at the upper end of the Ikaho hot spring district. It stands near the hot spring source and the Ikaho Open-Air Bath and is one of the area’s most recognizable scenic spots.
Fresh greenery makes the area particularly attractive in spring, while autumn brings brilliant foliage. During the autumn season, the bridge is sometimes illuminated at night, creating a magical atmosphere.
Maple, oak, lacquer, and other trees turn vivid shades of red, orange, and yellow, making the area especially popular during the fall foliage season.
Cultural and Hands-On Experiences in Ikaho
Ikaho offers much more than hot spring bathing. Bukkozan Housuiji Temple is a temple established as the Japanese headquarters of Fo Guang Shan, a Buddhist organization whose main headquarters are in Taiwan.
The temple features an expansive grounds and impressive architecture. Visitors can also take part in free experiences such as zazen meditation and sutra copying, providing an opportunity to enjoy a quiet and contemplative moment.
The Gunma Prefectural Comprehensive Sports Center Ikaho Rink is known as one of Japan’s largest skating facilities. It welcomes everyone from beginners to experienced skaters and can be enjoyed throughout the year.
Enjoying Nature Around Ikaho
The Ikaho Ropeway offers a scenic approximately four-minute aerial journey from the hot spring town to Miharashi Station. From the ropeway, visitors can enjoy broad views of the surrounding landscape.
After reaching the upper station, visitors can explore Uenoyama Park and the Ikaho Forest Park.
From the Tokimeki Deck observation area in Uenoyama Park, visitors can look across the Ikaho hot spring district and Shibukawa’s urban area. The park is also home to the Kibo Bell, known as a bell associated with good relationships and romantic connections.
At Ikaho Forest Park, visitors can enjoy forest bathing and hiking around Mount Futatsudake, one of the outer peaks of the Mount Haruna volcanic range. The area is particularly beautiful when azaleas bloom and when the forests turn red and gold in autumn.
Easy Day-Trip Hot Spring Experiences
Visitors do not need to stay overnight to enjoy Ikaho’s hot springs. Several bathing facilities welcome day visitors.
Ikaho Open-Air Bath is located near the source of Kogane-no-Yu and offers a simple outdoor bathing experience surrounded by nature.
Ishidan-no-Yu is a traditional public bath built in a warehouse-style structure along the stone steps, making it particularly convenient for visitors exploring the town.

History and Development as a Post Town
Shibukawa as a Transportation Hub
Shibukawa developed as a post town along the Mikuni Kaido, an important route connecting Takasaki via Kaneko with the Echigo region.
The town was also located where the Sado Bugyo Kaido, a route connecting Honjo and Sado Magistrate-related destinations via Sosha, joined the transportation network. As a result, Shibukawa became an important transportation center throughout the Edo period.
Town planning is believed to have begun around 1613, forming three main districts known as Kami-no-cho, Naka-no-cho, and Shimo-no-cho. Each district had a wholesaler responsible for handling goods and travelers.
Although the town did not have an official honjin or waki-honjin for feudal lords, records indicate that feudal lords from Echigo and officials connected with Sado stayed in the town during the late Edo period.
Markets and Horse Fairs
Shibukawa was also known as a lively market town where regular markets were held six times a month.
Markets were held on the 2nd and 17th in Kami-no-cho, the 7th and 22nd in Naka-no-cho, and the 12th and 27th in Shimo-no-cho. The first market is said to have begun in 1630 and played an important role in the local economy.
The town was also famous for its horse fairs, which are traditionally said to date back to the Oei period. Held three times a year—in spring, summer, and winter—the fairs attracted people from surrounding areas.
From the Modern Era to the Present
Municipal Development and Mergers
Shibukawa Town was established under the municipal system introduced in 1889. Following subsequent mergers, the former Shibukawa City was established in 1954.
The present-day city was created in 2006 through a merger with Ikaho Town, Onogami Village, Komochi Village, Akagi Village, and Hokkitsu Village.
Hot Springs and Leisure Experiences
Ikaho Onsen
The best-known tourist attraction in Shibukawa is undoubtedly Ikaho Onsen, one of Japan’s most famous hot spring resorts.
The resort spreads across the slopes of Mount Haruna, with the historic stone-step street at its center. The staircase has 365 steps, with souvenir shops, restaurants, traditional inns, and other businesses lining the route.
Walking up the steps one by one while exploring the traditional hot spring town is one of the defining experiences of Ikaho.
The two traditional spring waters—iron-rich Kogane-no-Yu and clear, gentle Shirogane-no-Yu—offer different bathing experiences. Ikaho has long been visited as a therapeutic hot spring resort and continues to attract travelers seeking relaxation today.
