History As with all of Tokushima Prefecture, the area of Miyoshi was part of ancient Awa Province. From the Muromachi period it was the seat of the Miyoshi clan, a once powerful warlord clan who ruled most of Shikoku and parts of Honshu.. During the Edo period, the area was part of the holdings of Tokushima Domain ruled by the Hachisuka clan from their seat at Tokushima Castle. Following the Meiji restoration, it was organized into 10 villages within Miyoshi District, Tokushima with the creation of the modern municipalities system on October 1, 1889, including the villages of Ikeda (池田村), Mino (三野村), Sanmyo (三名村), and Minawa (三縄村). Ikeda was raised to town status on October 1, 1905 and Mino on January 26, 1924. Sanyo and Minawa merged on September 30, 1956 to form the town of Yamashiro. The city of Miyoshi was established on March 1, 2006, from the merger between the towns of Ikeda, Ikawa, Mino and Yamashiro, (all from Miyoshi District) and the villages of Higashiiyayama and Nishiiyayama from Mima District.
