The ancient province of Gunma was a center of horse breeding and trading activities for the newly immigrated continental peoples. The arrival of horses and the remains of horse tackle coincides with the arrival of a large migration from the mainland. From this point forward, the horse became a vital part of Japanese military maneuvers, quickly displacing the older Yayoi tradition of fighting on foot.
When Mount Haruna erupted in the late 6th century, Japan was still in the pre-historical phase (prior to the importation of the Chinese writing system during the Nara period). The Gunma Prefectural archaeology unit in 1994 was able to date the eruption through zoological anthropology at the corral sites that were buried in ash.
In the past, Gunma was joined with Tochigi Prefecture and called Kenu Province. This was later divided into Kami-tsu-ke (Upper Kenu, Gunma) and Shimo-tsu-ke (Lower Kenu, Tochigi). The area is sometimes referred to as Jomo (上毛, Jōmō). For most of Japanese history, Gunma was known as the province of Kozuke.
In the early period of contact between western nations and Japan, particularly the late Tokugawa, it was referred to by foreigners as the "Joushu States", inside (fudai, or loyalist) Tokugawa retainers and the Tokugawa family symbol is widely seen on public buildings, temples, and shrines.
The Tenmei eruption of Mount Asama occurred in 1783, causing enormous damage.
The first modern silk factories were built with Italian and French assistance at Annaka in the 1870s.
In the early Meiji period, in what was locally called the Gunma Incident of 1884, a bloody struggle between the idealistic democratic westernizers and the conservative Prussian-model nationalists took place in Gunma and neighboring Nagano. The modern Japanese army gunned down farmers with new repeating rifles built in Japan. The farmers in Gunma were said to be the first victims of the Murata rifle.
In the twentieth century, the Japanese aviation pioneer Nakajima Chikushi of Oizumi, Gunma Prefecture, founded the Nakajima Aircraft Company. At first, he produced mostly licensed models of foreign designs, but beginning with the all-Japanese Nakajima 91 fighter plane in 1931, his company became a world leader in aeronautical design and manufacture, with its headquarters at Ota, Gunma Ken. The factory now produces Subaru motorcars and other products under the name of Subaru née Fuji Heavy Industries.
In the 1930s, German architect Bruno Julius Florian Taut lived and conducted research for a while in Takasaki.
The Girard incident, which disturbed US-Japanese relations in the 1950s, occurred in Gunma in 1957, at Soumagahara Base near Shibukawa.
Four modern prime ministers are from Gunma, namely, Takeo Fukuda, Yasuhiro Nakasone, Keizo Obuchi, and Yasuo Fukuda, the son of Takeo.
One of only eight landlocked prefectures in Japan, Gunma is the northwesternmost prefecture of the Kantō plain. Except for the central and southeast areas, where most of the population is concentrated, it is mostly mountainous. To the north are Niigata and Fukushima prefectures, while to the east lies Tochigi Prefecture. To the west lies the Nagano Prefecture, and the Saitama Prefecture is to the south.
Some of the major mountains in Gunma are Mount Akagi, Mount Haruna, Mount Myōgi, Mount Nikkō-Shirane and Mount Asama, which is located on the Nagano border. Major rivers include the Tone River, the Agatsuma River, and the Karasu River.
As of 1 April 2012, 14% of the total land area of the prefecture was designated as Natural Parks, namely Jōshin'etsu-kōgen, Nikkō, and Oze National Parks and Myōgi-Arafune-Saku Kōgen Quasi-National Park.

Because Gunma is situated in inland Japan, the difference in temperature in the summer compared to the winter is large, and there is less precipitation. This is because of the karakkaze ("empty wind"), a strong, dry wind that occurs in the winter when the snow falls on the coasts of Niigata. The wind carrying clouds with snow are obstructed by the Echigo Mountains, and it also snows there, although the high peaks do not let the wind go past them. For this reason, the wind changes into the kara-kaze.
Gunma's modern industries include transport equipment and electrical equipment, concentrated around Maebashi and the eastern region nearest Tokyo. More traditional industries include sericulture and agriculture. Gunma's major agricultural products include cabbages and konnyaku. Gunma produces over 90% of Japan's konnyaku, and two-thirds of the farms in the village of Tsumagoi are cabbage farms. Also, the city of Ōta is famous for the car industry, notably the Subaru factory.
There is a local dialect, known in Japanese as 'gunma-ben' or 'jōshū-ben'.
Gunma has a traditional card game called Jomo Karuta (上毛かるた). It features people, places, and things of regional and/or cultural importance.
In 2007, the Ministry of Agriculture, Forestry and Fisheries held an event to find the top 100 best local dishes across all of Japan. Three dishes were featured from Gunma; yaki-manju, okkirikomi, and konnyaku.
As of 2018, Gunma is home to eleven of Japan's over thirty Melody Roads. 2,559 grooves cut into a 175-meter stretch of the road surface in transmit a tactile vibration through the wheels into the car body. The roads can be found in Katashina, Minakami, Takayama, Kanna, Ueno, Kusatsu, Tsumagoi, Nakanojo, Takasaki, Midori, and Maebashi. Each is of a differing length and plays a different song. Naganohara also used to be home to a Melody Road playing “Aj, lučka lučka siroka”, though the road in question was paved over in 2013 due to noise complaints.
