Aizumi is a town located north of the Yoshino River from Tokushima city. During the Warring States period, the feudal lords of Awa were based here at Shozui Castle during the Muromachi era (1336-1573). Shozui became a prominent political and cultural centre in Shikoku, with influence extending right up to the Shogun of Japan.
During the 17th century, Tokushima city replaced Shozui as the main administrative centre of Tokushima, and the area declined over the centuries with most of the significant development in the region taking place in Tokushima city, south of the Yoshinogawa. For a long time Aizumi was an agricultural area with little urban development.
Today, you can visit the site of Shozui Castle, and try your hand at indigo dyeing at the fascinating Ai-no-Yakata museum.
