  ## History
  
  The area of present-day Tagajō was part of ancient Mutsu Province, and has been settled since at least the Jōmon period by the Emishi people. Per the Shoku Nihongi, following a huge earthquake in the year 715 AD, a large number of people migrated to this area from the southern Kantō region, forming numerous fortified settlements in the hinterland. In 729 AD, a large fortified settlement, Taga Castle, was established by the Yamato dynasty as a military center to establish control over the region and to protect these colonists. The fortification became the administrative capital of Mutsu Province under the Ritsuryō system. The tsunami in 869 caused extensive flooding of the Sendai plain, destroying the town of Tagajō. Archaeological investigations have identified the remains of 8th and 9th century buildings beneath the present town, covered by sediments dated to the middle of the 10th century.
  
  During the later portion of the Heian period, the area was ruled by the Northern Fujiwara. During the Sengoku period, the area was contested by various samurai clans before the area came under the control of the Date clan of Sendai Domain during the Edo period, under the Tokugawa shogunate.
  
  After the start of the Meiji period, the modern village of Tagajō was established with the creation of the municipalities system on April 1, 1889. From 1945 to 1954, a United States Army base, Camp Loper, was located in the town. Tagajō was elevated to town status on July 1, 1951. In the mid-1960s, the town was designated as an industrial development zone due to its proximity to Sendai harbor. Tagajō was designated a city on November 1, 1971. The city was seriously affected by the tsunami caused by the 2011 Tōhoku earthquake. As of April 7, 2011, 177 people were known dead, with 15 missing. 1,811 people were living in shelters.
