Shiwaku Islands

The Shiwaku Islands (塩飽諸島, Shiwaku-shotō) oder Shiwaku-jima (塩飽島) form an archipelago in the Japanese Inland Sea.

The group is situated between Okayama Prefecture and Kagawa Prefecture in the western Bisan Seto and consists of 28 islands of various sizes. On the Okayama side lie the Kasaoka Islands. The name derives from shioyaku (塩焼く) or shiowaku (潮湧く) both meaning boiling seawater to get salt. However, the name may also refer to rough water created by the confluence of tides that mix around the islands.
