Toyooka (豊岡市, Toyooka-shi) is a city in the northern part of Hyōgo Prefecture, Japan. As of 31 March 2022, the city had an estimated population of 78,348 in 37769 households and a population density of 110 persons per km. The total area of the city is 697.55 square kilometres (269.33 sq mi).

Toyooka is located in the northern part of Hyōgo Prefecture and the Kinki region, facing the Sea of Japan in the north. It lies entirely within the San'in Kaigan Geopark. The Maruyama River flows through the central part of the city, and the Toyooka Basin, which is the largest basin in the Tajima region, spreads out in the central part of the city. Toyooka is located in the "snow country" of Japan and is characterized by heavy accumulations of snow in winter. One of Toyooka's famous geological features is a basalt cave called Gembudō. Gembudō was formed 1.6 million years ago from the eruption of an ancient volcano. In 1926, Professor Motonori Matuyama of Kyoto University first proposed the theory of geomagnetic polarity reversal at Genbudo after discovering it had a reverse magnetization.

The wetlands of Toyooka provide an important habitat for the oriental stork. After becoming extinct in the wild in the 1970s, Toyooka began a captive breeding program. After a quarter of a century of breeding efforts, the first oriental stork chick was born in 1989. In 2005 Toyooka released 5 captively bred storks, which bred successfully in the wild. As of June 2015 there are 72 wild oriental white storks in Toyooka.

The hot spring resort Kinosaki Onsen is located within Toyooka.

Kyōtango has a humid climate (Köppen Cfa) characterized by warm, wet summers and cold winters with heavy snowfall. Although part of the Kansai region and Hyōgo Prefecture, Toyooka has a climate much more similar to the Hokuriku region of Chūbu and Tōhoku. Unlike Osaka or Kobe, which rarely see significant snowfall during the winter, Toyooka, exposed to the northerly winter winds driven by the Siberian High and Aleutian Low, receives 3.1 metres (122.0 in) of snowfall per year, though melt rates are high even during the winter and the maximum cover on the ground is typically only 0.35 metres (13.8 in) and has never exceeded 0.54 metres (21.3 in). Precipitation is much heavier than in central Kansai, though less heavy than in the Kii Peninsula or the Hokuriku region proper.

Per Japanese census data, the population of Toyooka in 2020 is 77,489 people. Toyooka has been conducting censuses since 1950.

Toyooka population statistics

The area of Toyooka was the center of ancient Tajima Province in the early 8th century and the location of the provincial capital and the Tajima Kokubun-ji. From the Muromachi period to the end of the Sengoku period, the area was under the stronghold of the powerful Yamana clan. Under the Edo Period Tokugawa shogunate, Toyooka Domain and Izushi Domain existed within the borders of what is now the city of Toyooka. In 1871, following the Meiji restoration, "Toyooka Prefecture" incorporating all of the former feudal territories within Tajima, Tango and Tanba Provinces was created. It was abolished on August 21, 1876, when Hyōgo Prefecture was created. The town of Toyooka was officially established with the creation of the modern municipalities system on April 1, 1889. The 1925 North Tajima earthquake created severe damage in Toyooka, with official government reports, indicating that there were 428 fatalities, 1,016 injuries, 7,863 buildings destroyed, and 45,659 houses damaged by collapse or fire.

The city of Toyooka was created on April 1, 1950 by the merger of Toyooka with neighboring Gosho, Nitta, and Nakasuji villages. The city expanded on April 1, 1955 by annexing Nasa and Minato villages. On April 1, 2005, the towns of Kinosaki, Hidaka and Takeno (all from Kinosaki District) and the towns of Izushi and Tantō (both from Izushi District) were merged into Toyooka.
