Shibukawa is located within traditional Kōzuke Province. During the Edo period, the area of present-day Shibukawa prospered from its location on the Mikuni Kaidō highway connecting Takasaki with Niigata. Post stations within the borders of modern Shibukawa were Shibukawa-shuku, Kanai-shuku, Kitamoku-shuku and Yokobori-shuku.
Shibukawa town was created in Nishigunma District, Gunma Prefecture on April 1, 1889, with the creation of the modern municipalities system after the Meiji Restoration. In 1896, Nishiguma District and Kataoka District merged to form Gunma District, Gunma; however, the area containing Shibukawa was separated out in October 1949 into Kitagunma District. On April 1, 1954, Shibukawa absorbed the villages of Furumaki, Kanashima and Toyoaki to become the city of Shibukawa.
On February 20, 2006, Shibukawa absorbed the town of Ikaho, the villages of Komochi and Onogami (all from Kitagunma District), and the villages of Akagi and Kitatachibana (both from Seta District).
Shibukawa has a mayor-council form of government with a directly elected mayor and a unicameral city council of 18 members. Shibukawa contributes two members to the Gunma Prefectural Assembly. In terms of national politics, the city is divided between the Gunma 1st district and the Gunma 5th district of the lower house of the Diet of Japan.
Shibukawa is a regional commercial center and transportation hub. Seasonal tourism, particularly to its hot spring and ski resorts, play a major role in the local economy.
The area is noted for its production of konjac.
Shibukawa has 14 public elementary schools and nine public middle schools operated by the city government, and four public high schools operated by the Gunma Prefectural Board of Education. The prefecture also operates two special education schools for the handicapped.
Kan-etsu Expressway – Shibukawa-Ikaho IC, Akagi IC
National Route 17
National Route 353Shibukawa calls itself "The Bellybutton of Japan" (日本のおへそ) and hosts the Bellybutton Festival (へそ祭り) every year in late July. The festival is based on a traditional Japanese form of entertainment where revelers paint a face on their torsos and stomachs and pretend it is a head. A kimono is then wrapped around the waist and the person's real head is hidden by a large cloth hat. The belly button is traditionally painted into a mouth. These days, modern motifs and Japanese anime designs have crept into the festival, which city officials said is all about having fun.[4][5]
