The government adopted Friday a policy package aimed at reducing plastic waste ahead of the Group of 20 summit in Osaka in late June, where the issue is expected to be a major agenda item.

The policies are intended to cut the flow of plastic waste into the ocean, promote plastic-bottle recycling in Japan and combat marine pollution by microplastics.

"Ocean plastic waste is one of the issues topping the G20 summit agenda. As the chair of the meeting, we will exercise leadership to solve the matter," Prime Minister Shinzo Abe told a ministerial conference, which finalized the policy package.
