The Seto Inland Sea in western Japan has been a major sea route since ancient times. The Geiyo Archipelago, of large and small islands, crisscrosses the inland sea between Hiroshima and Ehime Prefectures. The mighty Murakami pirates' base ruled these waters from the 14th to 16th centuries. In times of civil war, they allied with warlords using their military might, helping shape history. The primary objective of their activity was not looting, but maintaining order by guaranteeing safe passage of ships for a fee. They even engaged in trade with foreign countries. Tatsumasa Murasame, who is originally from Sweden but has assumed Japanese citizenship, visits the Geiyo Islands to trace this little known chapter of history. And he discovers the people's feelings of awe for the pirates, which have been passed down through the generations.
