Какамигахара: История, природа и развитие города

Situated in the northern part of the Nōbi Plain, what is now Kakamigahara originally thrived as a post station on the Nakasendō highway connecting Edo with Kyoto, being called "Unuma juku" at the time. In more recent history, the city developed due to the JASDF Gifu base. In addition, Kakamigahara grew as an industrial city and a commuter suburb of Gifu City and Nagoya. The city of Kakamigahara has many large parks, the most notable among them being "Kakamigahara Kōen", which was originally made from a vacant lot owned by Gifu University. A city planning policy of making Kakamigahara into a "park city" has been undertaken by the municipality, and in 2005, the city received the Green City Prize from the prime minister. Although the city was officially named Kakamigahara, it is also called Kakamihara, Kagamihara, or Kagamigahara by tradition.

Mountainous terrain runs from the northern to the eastern part of the city. The Kiso River flows through the southern part, forming the municipal and prefectural (Aichi Gifu) border. A large portion of the city is situated on the Kakamigahara Plateau. Because the soil is very well drained, it was not traditionally suited to rice cultivation. With the exception of rest stops such as Unuma juku or other roadside settlements, though, the area was largely wilderness until the Meiji period. The names of the Meitetsu train stations, Rokken, Nijukken, and the Ogase Reservoir are from that era. Beginning from the Meiji period, to take advantage of the large amount of wilderness and well drained soil, military bases and training grounds were established. In addition, Gifu University's agricultural and engineering departments were established in the area, leading the growth of machine and textile factories. These industries, in addition to carrot production, which used the dry soil, became the main industries of the town. Part of the city is within the borders of the Hida Kisogawa Quasi National Park.

The city has a climate characterized by hot and humid summers, and mild winters (Köppen climate classification Cfa). The average annual temperature in Kakamigahara is 15.5 °C. The average annual rainfall is 1939 mm, with September as the wettest month. The temperatures are highest on average in August, at around 27.9 °C, and lowest in January, at around 3.9 °C.

The area around Kakamigahara was part of traditional Mino Province. During the post Meiji restoration cadastral reforms, the area was organised into Inaba District, Gifu in April 1897. 1 April 1963: Kakamigahara City was founded by amalgamating Naka, Sohara, Unuma, and Inaba. 1968: The Line Bridge was completed. Together with the Inuyama bridge, completed in 1925, these two bridges span the Kiso River and connect Kakamigahara City with Aichi Prefecture. 1969: The Aigi bridge was completed. This was the third bridge to span the Kiso, and connects the city to Aichi Prefecture. It was the first bridge to connect Kakamigahara to Konan City. 5 March 1986: The section of the Tokai Hokoriku Expressway between Kakamigahara Junction and Mino Junction was opened. Furthermore, on 13 December 1998, the Tokai Hokoriku Expressway was connected to the Meishin Expressway (Ichinomiya Junction). 28 March 2000: The twinning of the Inuyama Bridge was completed. Previously, Meitetsu trains had shared the bridge with automobiles, crossing the bridge in a manner similar to streetcars. After the twinning, the trains began to use the old Inuyama Bridge. This separation of trains and automobiles improved transportation across the river. 1 November 2004: Kawashima cho (Hashima District), was incorporated in Kakamigahara City. 5 November 2006: The Shin mei Ko ami Bridge, connecting to Konan, is completed. 24 March 2013: Kakamigahara Bridge is completed. It connects the city hall area with Kawashima chiku (formerly Kawashima cho) of Konan City. With the completion of this bridge, there are now four routes from Kakamigahara City into Aichi Prefecture.

Kakamigahara City is second in Gifu Prefecture in terms of industrial production. The city has an aircraft factory operated by Kawasaki Heavy Industries Aerospace Company, located next to the JASDF Gifu Air Base, and Mitsubishi Heavy Industries also produces aircraft parts. The city also has many automobile related factories, including parts makers and metalworking industries. In Sue cho in the north of Kakamigahara City, an industrial park called Techno Plaza was established by the Gifu Prefectural government as a focal point for the research and development of robotics and virtual reality. With Waseda University's WABOT HOUSE laboratory and Gifu University's Science and Technology Promotion Center as a nucleus, Techno Plaza is structured as an industrial and R&D center. Many ventures have moved into the park, including some companies that have made IPOs, such as Nippon Ichi Software, Inc.

Kakimigahara has 16 public elementary schools and eight public junior high schools operated by the city government. The city also operates one special education school.

Aigi Ohashi Bridge crosses the Kiso River into Inuyama in Aichi Prefecture.

JASDF Gifu Air Base was established as an army airfield in 1917, and is currently used by the JSDF for aircraft and flight testing. From 1945 to 1958, it was occupied by the U. S. military and known as "Camp Gifu".
