Kimitsu (君津市, Kimitsu-shi) is a city located in Chiba Prefecture, Japan. As of 30 November 2020, the city had an estimated population of 83,058 in 39,138 households and a population density of 260 persons per km².^[1] The total area of the city is 318.83 km² (123.10 sq mi).

The area along Tokyo Bay is in the Kimitsu district of Kisarazu Port, and it is a heavy industrial area centered around Nippon Steel (formerly Yahata Steel and Nippon Steel). The city area is mostly located along the coast around Kimitsu Station. In the inland Kururi area, the JR Kururi Line runs through, and it was a castle town of the Kururi Domain during the Edo period, with historical streets still remaining.

The underground water from the Kiyosumi and Mitsuishi mountain ranges was chosen as one of the "Top 100 Famous Waters of Heisei" and is called "Living Water of Kururi." Kururi is the top producer in Japan of kallos (wetland plants) using the spring water.

In the late 1960s, about 20,000 people from Kyushu moved to the area when the Yahata Steel factory opened. This is known as the "Great Migration," and Kyushu culture still remains in many parts of the region.

Kimitsu is located in the southwestern part of Chiba prefecture, about 35 kilometers from the prefectural capital at Chiba, and 40 to 50 kilometers from the center of Tokyo. The northwestern part of the city faces Tokyo Bay and forms a part of the expansive Keiyo Industrial Zone. The inland area is lined with mountains in the Bōsō hills. The city area is the second largest area in Chiba prefecture after Ichihara city. Two small rivers cross Kimitsu, the Koito River and the Obitsu River.

Kimitsu has a humid subtropical climate (Köppen Cfa) characterized by warm summers and cool winters with light to no snowfall. The average annual temperature in Kimitsu is 14.2 °C (57.6 °F). The average annual rainfall is 2,046.5 mm (80.57 in) with October as the wettest month. The temperatures are highest on average in August, at around 25.3 °C (77.5 °F), and lowest in January, at around 3.5 °C (38.3 °F).^[2]

Per Japanese census data,^[4] the population of Kimitsu peaked around the year 2000 and has declined since.

The area of present-day Kimitsu was largely part of the Kururi Domain under the Edo period Tokugawa shogunate, centered on the jōkamachi of Kururi Castle. It was divided between Moda District and Sue District in the early Meiji period cadastral reforms. Both districts became part of Kimitsu District from April 1, 1897. The village of Susaki and Yaehara were created with the establishment of the modern municipalities system on April 1, 1889. Kimitsu Town was founded by the merger of these villages on April 1, 1943, and expanded through annexation of two neighboring villages of Sunami and Sadamoto on April 1, 1944. The town continued to expand by annexing the towns of Kazusa and Koito and the villages of Seiwa and Obitsu on September 28, 1970. Kimitsu was elevated to city status on September 1, 1971. ^{[citation needed]}

Before Kimitsu City was established, Kimitsu Town went through three mergers in 1943, 1954, and 1970. Except for the 1954 merger, which was based on the Town and Village Merger Promotion Law (known as the "Great Merger of Showa"), the other two mergers had no relation to national policies.

In 1943, when the first Kimitsu Town was formed, Japan was in the middle of World War II. The Yaehara Factory, a branch of the Kisarazu Naval Air Corps, was built on a large area of land across Yaehara Village and Susai Village. Because of this, there were issues like moving houses, buying farmland, and distributing food and clothes for workers. With help from the Japanese military, the two villages merged to create "Kimitsu Town."

The 1970 merger was influenced by the Yahata Steel Factory (now Nippon Steel Kimitsu Works) that moved into the coastal area during the 1960s. The factory increased property tax income for Kimitsu Town. However, if the population was too small, part of the tax would go to Chiba Prefecture. To prevent this, the town merged with other nearby areas to increase the population. At first, Kisarazu City was also part of the merger talks, and a new city name, "Kimitsu-Kisarazu City," was suggested. But since Kisarazu City did not agree, the plan was dropped. On September 28, 1970, five towns and villages merged, creating the new "Kimitsu Town." After reaching the population requirements, Kimitsu Town became Kimitsu City on September 1, 1971, becoming the 25th city in Chiba Prefecture.

Kimitsu has a mayor-council form of government with a directly elected mayor and a unicameral city council of 22 members. Kimitsu contributes two members to the Chiba Prefectural Assembly. In terms of national politics, the city is part of Chiba 12th district of the lower house of the Diet of Japan.

Despite its short coastline on Tokyo Bay, the economy of Kimitsu is centered around its coastal belt of heavy industries, primarily by the large-scale steelworks of Nippon Steel's Kimitsu Works. Kimitsu Works was established in 1965, covers 11,720,000 square metres (126,200,000 sq ft), and employed 3,280 people as of 2007.^[5] The Koito Fishing Port, technically located in both Kimitsu and Futtsu, is located just north of Cape Futtsu at the mouth of the Koito River. Entry in and out of the fishing port suffers from sediment deposited by the Koito.^[6] Kazusa Akademia Park, which spans both Kimitsu and Kisarazu, was established to carry out research in biotechnology and information technology.^[7]

Kimitsu has 17 public elementary schools and seven public middle schools operated by the city government, and three public high schools operated by the Chiba Prefectural Board of Education. There is also one private middle school and one private high school. The prefecture also operates one special education school for the handicapped.
