If producing plastic waste were a race, Japan would be rushing for the gold medal. Japan and the United States both rank the highest per capita for plastic packaging waste in the world. Former Prime Minister Shinzo Abe’s administration set a goal to reduce Japan’s plastic waste production by 25 percent by 2030 and recent polls show the majority of the Japanese public wants strong actions to reduce plastic waste. Nevertheless, Japan is not doing enough to stem the tide of plastic entering the ocean. If Japan and the rest of the world fail to act more boldly, global oceanic plastic waste could triple by 2040. Current commitments of governments and corporations would only reduce global plastic leakage seven percent below the business-as-usual scenario. Japan’s current waste management system prioritizes recycling and incineration, encouraging a make-take-waste linear model of plastic consumption. Japan needs a circular economy built on a culture of reduction and reuse instead of single-use plastics.
