Ibaraki Prefecture

In Japanese Paleolithic, humans are believed to have started living in the present-day prefecture area before and after the deposition of the volcanic ash layer from the Aira Caldera about 24,000 years ago. At the bottom of this layer are local tools of polished stone and burnt pebbles.

During the Asuka period the provinces of Hitachi and Fusa were created. Later Fusa was divided, among them, the Shimōsa Province.

At the beginning of the Muromachi period, in the 14th century, Kitabatake Chikafusa made of the Oda Castle his field headquarters for over a year, and wrote the Jinnō Shōtōki (Chronicles of the Authentic Lineages of the Divine Emperors), while he was at castle.

In Edo period, one of the three houses or clans originating from Tokugawa Ieyasu (Gosanke 御 三家, three houses), settled in the Mito Domain, known as Mito Tokugawa family or Mito Clan. Mito Domain, was a Japanese domain of the Edo period it was associated with Hitachi Province.

In 1657 the Mitogaku school was created, when Tokugawa Mitsukuni, head of the Mito Domain, commissioned the compilation of the Dai Nihonshi.

In Meiji era, during the Meiji Restoration, the political map changes, the old provinces are converted or merged, to create the current prefectures, in this case the Ibaraki Prefecture.

As of 1 April 2012, 15% of the total land area of the prefecture was designated as Natural Parks, namely Suigo-Tsukuba Quasi-National Park, and nine Prefectural Natural Parks.[3] Also, Ibaraki has one Prefectural Geopark. The Suigo-Tsukuba Quasi-National Park, also includes the northeast area of Chiba Prefecture.

The northern third of the prefecture is mountainous and in the center is the Tsukuba Mountains (筑波 山地). Its main mountains are: mount Yamizo with an elevation of 1022 m on the border with Fukushima and Tochigi prefectures (tripoint), mount Takasasa with 922 m, mount Tsukuba with two peaks Nyotai-San at 877 m and Nantai-San at 871 m, mount Osho at 804 m, mount Hanazono at 798 m, and mount Kaba at 709 m.

The main rivers that flow through the prefecture include the Tone, Naka (Ibaraki), and Kuji rivers, all of which flow into the Pacific Ocean. Before the seventeenth century, the lower reaches of the Tone were different from its current layout, and the Tone ran south and emptied into Tokyo Bay, and tributaries such as the Watarase and Kinu rivers had independent water systems.

The main tributaries of the Tone River basin are the Kinu River and Kokai River, which flow from north to south in the western part of the prefecture. The Shintone and Sakura rivers flow into Lake Nishiura.

The Edo River flows into Tokyo Bay; its source currently rises as an arm of the Tone River. In the past, the course of the Edo River was different, its source was corrected and diverted to the Tone River in the 17th century by the Tokugawa shogunate to protect the city of Edo (now Tokyo) from flooding.

The Tone River, in addition to the Edo River, is part of the southern border of Ibaraki Prefecture with Chiba Prefecture, and the Watarase River, Tone River, Gongendō River, and Naka River (Saitama) in the southwestern border of Ibaraki with Saitama Prefecture. The Watarase River has become a small boundary of the southern border between Ibaraki and Tochigi prefectures.

From ancient times to the beginning of the Edo period, the lower reaches of the Tone River did not exist and the mouth of the Tone was in Tokyo Bay. On the plain was the Katori Sea, which existed in ancient times,[4] the Lake Kasumigaura and other lagoons in present-day Chiba prefecture are remnants of that sea. Katori Sea was connected to the Kashima-nada (Pacific Ocean).

Lake Kasumigaura is currently divided into three lakes: Nishiura, Kitaura, Sotonasakaura. In addition, in the prefecture there are freshwater lagoons such as Hinuma, Senba, and Ushiku.

Fukuoka Dam, is a dam that spans the Kokai River in Tsukubamirai, it is one of the three largest dams in the Kantō region. Ryūjin Dam in Hitachiōta, is a beautiful dam on the Ryuujin River with a large pedestrian suspension bridge above the dam lake.

Thirty-two (32) cities are located in Ibaraki Prefecture:

These are the towns and villages in each district, 10 towns and 2 villages in 7 districts:

With extensive flat lands, abundant water, and suitable climate, Ibaraki is among the prefectures with the highest agricultural production in Japan. It plays an important role in supplying food to the Tokyo metropolitan area. Its main products include melons, pears, peppers, various varieties of rice and sugar cane, as well as flowers and ornamental plants.

It also supplies other food crops to the rest of the country. As of March 2011, the prefecture produced 25% of Japan's bell peppers and Chinese cabbage.[7]

It is one of the prefectures with the highest fish production in the country; in the Pacific Ocean, Lake Kasumigaura, other lagoons and rivers, various species of fish are obtained.

The Hitachigyū cattle (常 陸 牛 - ひたちぎゅう - Hitachi-gyū, Hitachi-ushi), which is a prefectural bovine breed, is noteworthy in livestock. The name comes from the kanji 常 陸 (Hitachi), the name of the ancient Hitachi Province and 牛 (ushi or gyū, beef).[8]

Background. In 1833 Tokugawa Nariaki (徳川 斉昭) established the breeding of black cattle in the present Migawa-chō (見川 町) of the city of Mito. Originally it remained mainly in the northern part of the prefecture, but later it spread throughout the prefecture.
