History
The most of the area of present-day Ōda located in Iwami Province, although an eastern portion of the city was within the borders of Izumo Province. The area was a meeting point of three ancient transportation routes: the San'indō, Izumo Kaidō, and the Bingo Kaidō. As a result, numerous market towns were developed in the area.[1] WIth the development of the Iwami Ginzan Silver Mine, the area was maintained as tenryō, or territory under the direct control of the Tokugawa shogunate throughout the Edo Period. The village of Ōda within Ano District, Shimane was established on April 1, 1889 with the creation of the modern municipalities system. Ōda was raised to town status on November 6, 1903. Ōda merged with the neighboring villages of Nagahisa, Torii, Kute, Hanehigashi, Kawai, Shizuma, and Kuri on November 1, 1954 and was raised to city status.
On October 1, 2005, the towns of Nima and Yunotsu (both from Nima District) were merged into Ōda. Therefore, Nima District was dissolved as a result of this merger.
