Prehistory Human settlement in the Tsuchiura area dates to the
Japanese Paleolithic period.
Hunter-gatherers inhabited the coastal area of the Pacific Ocean (now Lake Kasumigaura) forming large
shell middens, examples of which can be seen at the Kamitakatsu archeological site. Migrants from the Asian mainland brought
wet-rice cultivation, as well as iron and bronze technology, during the
Yayoi period. In the
Kofun period numerous
burial mounds were constructed in the area.
8th to 19th centuries During the
Nara period the area was organized under the
Taihō Code, and what is now Tsuchiura occupied four districts of
Hitachi Province. In 939, during the
Heian period,
Taira no Masakado led an uprising against the central government by attacking the
provincial capital at
Ishioka, a few kilometers north of Tsuchiura. During the
Kamakura and the
Sengoku periods, the area was dominated by several
samurai clans. During the
Edo period, part of what is now Tsuchiura was administered as a
castle town by
Tsuchiura Domain, one of the
feudal domains under the
Tokugawa shogunate. The area prospered due to its position on the Mito Kaidō, a highway connecting
Edo with
Mito, and on a canal connecting
Lake Kasumigaura to
Edo Bay.
Modern period With the creation of modern municipalities after the
Meiji Restoration, the town of Tsuchiura was established on April 1, 1889, within Ibaraki Prefecture. Railroad service was started in Tsuchiura in 1895. The
Gothic Revival architecture of the old junior high school from this period can be seen at the Dai'ichi high school. Tsuchiura was elevated to city status when the towns of Manabe and Tsuchiura were merged on November 3, 1940. During
World War II, the city suffered damage in an air raid on June 10, 1945. On September 1, 1951, Tsuchiura absorbed parts of the village of
Asahi on the shore of Arakawa and also absorbed the village of Towa. The city absorbed the village of Kamiotsu on November 1, 1954. On February 20, 2006, the village of
Niihari (from
Niihari District) was merged into Tsuchiura. ==Government==
