Under the Meiji period establishment of the modern municipalities system, the towns of Miyako and Kuwagasaki were established within Higashihei District. The area was devastated by a tsunami in 1896, which killed 1,859 inhabitants. Higashihei District became part of Shimohei District on 1 April 1897. Miyako and Kuwagasaki merged on 1 April 1924. On 3 March 1933, much of the town was destroyed by the 1933 Sanriku earthquake, which killed 911 people and destroyed over 98% of the buildings in the town. Miyako attained city status on 20 June 1940.
