Ibaraki Prefecture was previously known asHitachi Province. In 1871, the name of the province became Ibaraki, and in 1875 it became its current size, by annexing some districts belonging to the extinctShimōsa Province.
In theJapanese 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 theAira Caldera about 24,000 years ago. At the bottom of this layer are local tools of polished stone and burnt pebbles.
At the beginning of theMuromachi period, in the 14th century,Kitabatake Chikafusa made of theOda Castle his field headquarters for over a year, and wrote theJinnō Shōtōki (Chronicles of the Authentic Lineages of the Divine Emperors), while he was at castle.

In 1657, aMitogaku was created whenTokugawa Mitsukuni, head of the Mito Domain, commissioned the compilation of theDai Nihonshi, a book on the history of Japan.
As of 1 April 2012[update], 15% of the total land area of the prefecture was designated asNatural Parks, namelySuigo-Tsukuba Quasi-National Park, and nine Prefectural Natural Parks.[6] 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, andmount Kaba at 709 m.
The main rivers that flow through the prefecture include theTone,Naka (Ibaraki), andKuji rivers, all of which flow into thePacific Ocean. Before the seventeenth century, the lower reaches of the Tone were different from its current layout, and the Tone ran south and emptied intoTokyo Bay, and tributaries such as the Watarase and Kinu rivers had independent water systems.
The main tributaries of the Tone River basin are theKinu 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.
TheEdo 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 ofEdo (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 theWatarase River, Tone River, Gongendō River, andNaka 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 theKatori Sea, which existed in ancient times,[7] theLake 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 inTsukubamirai, it is one of the three largest dams in the Kantō region. Ryūjin Dam inHitachiōta, is a beautiful dam on the Ryūjin River with a large pedestrian suspension bridge above the dam lake.
Ibaraki's economy is based on energy production (particularly nuclear energy), chemical and precision machining industries, research institutes, and tourism. Agriculture, fishing, and livestock are also important sectors in the prefecture.[8]
Ibaraki's vast flat terrain make it highly suitable for industrial development. This complements its proximity to the Tokyo metropolitan area, giving it a high reputation as an industrial base. The prefecture is also home toTsukuba, Japan's most extensive research and academic city, and the birthplace ofHitachi, Ltd.[9]

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.[10]
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).[11]

The prefecture is often alternatively pronounced "Ibaragi" by those who speak the regional dialect known as Ibaraki-ben. However, the standard pronunciation is "Ibaraki". According to the author of "Not Ibaragi, Ibaraki",[16] this is most likely due to a mishearing of the softening of the "k" sound in Ibaraki dialect.
