Iyo Province
Iyo Province was an old province of Japan in the area that is today Ehime Prefecture on Shikoku. Iyo bordered on Awa, Sanuki, and Tosa Provinces. It was sometimes called Yoshū.History
The ancient provincial capital was near modern Imabari. During the Sengoku period it was split into several fiefs, the largest one usually being run from Matsuyama Castle in Matsuyama. It was briefly unified by the Chōsokabe clan of neighboring Tosa, but Toyotomi Hideyoshi invaded Shikoku in 1584 and reallocated the fiefs. During the Edo period the province was controlled by Uwajima Domain.
