Japanology Plus (2014) : 9x26

Around 500 years ago, sea traffic in the Seto Inland Sea was monitored and controlled by a group called the "Murakami Kaizoku." The word "kaizoku" translates to "pirates," but these seafarers weren't thieves; they actually helped to keep the area safe. In the second of two episodes about the Murakami Kaizoku, we go to the clan's island birthplace and visit a home that has many related historical artifacts. We also learn how the story of the Murakami Kaizoku is being told in fiction and drama.
