List of Shooto Pacific Rim champions

In 2005 the Shooto Organization decided to create splinter Shooto organizations around the world, with their own rankings and champions. Along with a European and American Shooto organization, a Pacific Rim organization was created focusing on Asia (but mostly Japan). This is the title history for the Pacific Rim titles.
