history

Ancient Times

The Iwajuku ruins, which are renowned for being the first evidence that a Stone Age culture existed in Japan, were discovered in Kasakake Town in 1946. The discovery was crucial in proving the existence of a culture in Japan that pre-dated that of the Jomon period.
Also, the discovery of 8,400 burial mounds throughout the prefecture , believed to have been built when the region was called "the Kozuke district", indicate that Gunma had been the center of Eastern Japan since the time of the Yamato dynasty.
The Kozuke district, along with the Shimotsuke district (now known as Tochigi Prefecture) was at the forefront of the culture of the Yamato dynasty, which originated from Western Japan.

Medieval Times
The samurai warrior class, represented by the Nitta clan, played an active role in shaping society, with one of their key roles being the protection and control of the manors of their lords. In particular, Yoshisada Nitta, who toppled the Kamakura shogunate, is famous for being included in the military epic of Taiheiki. With the advent of the Warring States Period, dominant clans such as the Uesugi clan, the Takeda clan and the Hojo clan engaged in territory disputes and a century of conflict and strife ensued.

When the Tokugawa shogunate finally succeeded in reunifying the entire nation, it saw the Kozuke District (Gunma), located in the northern Kanto area, as being strategically important. Due to this, the shogunate refused to delegate command to the large, estate-owning feudal lords for fear of losing control.
The Kozuke district was also a transportation hub for the region. Many main roads such as the Nakasendo Highway, the Mikuni Highway and the Nikko-Reiheishi Highway were developed, barrier stations set up, and post stations thrived considerably.
With regards to industry, the sericulture and silk textile industry developed, which set the stage for the rise of business tycoons such as Jubei Nakaiya, who entrepreneured raw silk trading in Yokohama in the twilight years of the Edo era.

Contemporary Times

The title of 'Gunma Prefecture' was officially used for the first time in 1871. Its present-day form was roughly formed in 1876, with Maebashi designated as the prefectural capital. The area's main industry focused around sericulture and silk reeling and spinning which, along with the development of a regional transportation network, gained momentum toward modernization.
In recent times, high-speed transportation networks in particular have dramatically improved. In 1972 the Tohoku Expressway, whose starting point is located in Kawaguchi, Saitama Prefecture, was extended to Tatebayashi interchange. And in 1980, the Kan-etsu Expressway, whose starting point is Nerima, Tokyo, was extended to Maebashi interchange and subsequently fully opened to traffic in 1985.
In 1982 the Joh-etsu Shinkansen line began operating and was extended to Tokyo station. The Joh-shin-etsu Expressway, opened to traffic in 1996, has been playing an important role in attracting tourists not only from the Tokyo metropolitan area but also from areas along the Sea of Japan, Nagano Prefecture and the Chukyo area.
Currently, the Kita-Kanto expressway, which is to run through the three prefectures of Gunma, Tochigi and Ibaraki, is under construction.
Gunma's population has steadily been increasing from about 500,000 in the early years of the Meiji period to about 1 million in 1912, then to 2 million in October, 1993.
In 1999, a 33 storey Prefectural Government Office building was constructed, and has become a symbol of the way the government is working together with its citizens in order to make Gunma Prefecture an even better place to live in the future.
