As the world’s largest seafood supplier, Japanese company Maruha Nichiro has a mission to nurture and protect the finite natural resources it harvests. But the message about the company's global conservation efforts wasn’t getting across—the public still viewed it as a big commercial fisher. The company developed a poster campaign that used vivid, dynamic photography to celebrate the world. However, across each image was a provocative, obscuring solid tone bar, suggestive of the “stop” bar in "prohibition symbol" signage. The images compelled viewers to pause and think about our shared role within nature as consumers and guardians. The bars have meanwhile become an emblem for Maruha Nichiro itself: bright, significant, and responsible.
