This chapter is developed to the Plastic Atlas Japan Special Edition プラスチック・アトラス アジア［日本語特別版］. As discussed by the chapter, Japan has introduced numerous innovative policies and strategies to promote the circulation of resources and to build a sustainable society. The Japanese experience shows that building an adequate waste management system is a sine qua non for curbing plastic pollution. Nonetheless, this alone is not sufficient for addressing the global plastic problem. Additional actions to curb the generation of plastic waste at the initial stages of the plastic lifecycle, namely the production stage, are also crucial. In order to reach this point, governments, corporations, consumers, and other stakeholders all need to take responsibility during both production and consumption.
