 This video report details the work by Peter Shapinsky of the University of Illinois – Springfield, related to Japanese pirates from the 15th and 16th centuries. Professor Shapinsky discusses how his research is able to show Japanese history from the perspective of the sea. He also finds records that show these pirates were more than violent criminals, as they also helped to establish trade routes, transport goods and provide protection.
