Ibaraki Prefecture (茨城県, Ibaraki-ken) is a prefecture of Japan located in the Kantō region of Honshu.[1] Ibaraki Prefecture has a population of 2,903,925 (2017) and has a geographic area of 6,097 km2 (2,354 sq mi). Ibaraki Prefecture borders Fukushima Prefecture to the north, Tochigi Prefecture to the northwest, Saitama Prefecture to the southwest, and Chiba Prefecture to the south.

Mito is the capital and largest city of Ibaraki Prefecture, with other major cities including Hitachi, Hitachinaka, and Tsukuba.[2] Ibaraki Prefecture is located on Japan's eastern Pacific coast to the northeast of Tokyo, and is part of the Greater Tokyo Area, the most populous metropolitan area in the world. Ibaraki Prefecture features Lake Kasumigaura, the second-largest lake in Japan, and Mount Tsukuba, one of the most famous mountains in Japan. Ibaraki Prefecture is home to Kairaku-en, one of the Three Great Gardens of Japan, and is an important center for the martial art of Aikido.


Ibaraki Prefecture was previously known as Hitachi Province. In 1871, the name of the province became Ibaraki.

Ibaraki Prefecture is the northeastern part of the Kantō region, stretching between Tochigi Prefecture and the Pacific Ocean and bounded on the north and south by Fukushima Prefecture and Chiba Prefecture. It also has a border on the southwest with Saitama Prefecture. The northernmost part of the prefecture is mountainous, but most of the prefecture is a flat plain with many lakes.

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]

Ibaraki is an agricultural prefecture contributing more or less to Japanese dining tables. As of March 2011, the prefecture produced 25% of Japan's bell peppers and Chinese cabbage.[4]


Ibaraki's population is decreasing more rapidly than any other prefecture.[5]


Ibaraki is known for nattō, or fermented soybeans, in Mito, watermelons in Kyōwa (recently merged into Chikusei), and chestnuts in the Nishiibaraki region.

Ibaraki is famous for the martial art of Aikido founded by Ueshiba Morihei, also known as Osensei. Ueshiba spent the latter part of his life in the town of Iwama, now part of Kasama, and the Aiki Shrine and dojo he created still remain.[6]

There are castle ruins in many cities, including Mito, Kasama, and Yūki.

Kasama is famous for Shinto, art culture and pottery.[citation needed]

The capital Mito is home to Kairakuen, one of Japan's three most celebrated gardens, and famous for its over 3,000 Japanese plum trees of over 100 varieties.

The prefecture is often alternatively pronounced "Ibaragi" by those who speak the regional dialect known as Ibaraki-ben. However, the correct pronunciation is "Ibaraki". According to the author of "Not Ibaragi, Ibaraki",[8] this is most likely due to a mishearing of the softening of the "k" sound in Ibaraki dialect.
