History
The ancient province of Gunma was a center of horse breeding and trading activities for the newly immigrated continental peoples (or
Toraijin). 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
Westernisers 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 near
Shibukawa.
Four modern prime ministers are from Gunma, namely,
Takeo Fukuda,
Yasuhiro Nakasone,
Keizo Obuchi, and
Yasuo Fukuda, the son of Takeo.

Mergers
Climate
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''.
