Iwami Province

Iwami bordered Aki, Bingo, Izumo, Nagato, and Suō provinces.

From the sixteenth century onwards, it played an important role in East Asia's economic history as a major silver source.

During the Muromachi and Sengoku periods, the battles were very furious in this area.

On 16 June 1026, a 10 m (33 ft) tsunami struck the Sea of Japan coast of present-day Masuda, Shimane, killing more than 1,000 people.
