Natori, Miyagi  Natori is in east-central Miyagi Prefecture, bordered by the Pacific Ocean to the east. Natori is located in the fertile plains of the Natori River and the Masuda River deltas; however, the Natori River is actually not inside Natori city limits. Traditionally, the area known as Natori District extended from the Natori River in the north and into the west. However, these regions have been absorbed into the greater Sendai area and are no longer part of Natori. Miyagi Prefecture  Natori has a humid climate (Köppen climate classification "Cfa") characterized by mild summers and cold winters. The average annual temperature in Natori is 12.6 °C. The average annual rainfall is 1252 mm with September as the wettest month. The temperatures are highest on average in August, at around 24.9 °C, and lowest in January, at around 1.5 °C. Per Japanese census data, the population of Natori has increased over the past 40 years. The area of present-day Natori was part of ancient Mutsu Province, and was under control of the Date clan of Sendai Domain during the Edo period, under the Tokugawa shogunate. In 1867, Natori came within the borders of the new Rikuzen Province, which later became part of Miyagi Prefecture. With the establishment of the modern municipalities system on April 1, 1889 Natori District was formed with six villages: Masuda, Higashi-Taga, Shimo-Masuda, Tatekoshi, Aishiwa and Takadate. On April 1, 1896 Masuda was elevated to town status as was Higashi-Taga on April 1, 1928. On April 1, 1955 the towns of Masuda and Yuriage, and the villages of Shimo-Masuda, Tatekoshi, Aishiwa and Takadate were merged to create the town of Natori, which was elevated to city status on October 1, 1958. The official boundaries of Natori City have changed since 1958, as Sendai City redefines its area to include districts to the north and west of Natori. The area was badly affected by the 2011 Tōhoku earthquake and tsunami. Large portions of the coastal area including Sendai Airport was severely damaged by the tsunami. On March 14, rescue workers arrived in an area of Natori known as Yuriage and found few survivors, as much of the Yuriage area was wiped out.
