Efforts to Combat Marine Litter in Japan and Future Tasks
AI summary Read the abstract
This paper reviewed Japan's efforts to combat marine litter, including the 2009 Shoreline Debris Management Promotion Act and its 2018 amendment that first incorporated microplastic countermeasures into law. The article described the Ministry of Environment's integrated approach covering waste collection, prevention, monitoring, and international cooperation.
海洋プラスチックごみによる海洋生態系への影響が国際的に懸念されており，海洋ごみ問題は地球規模の重要課題となっている。日本では，2009 (平成 21) 年に議員立法として成立した海岸漂着物処理推進法に基づき閣議決定された基本方針等に従い，海洋ごみ対策を推進している。環境省では，海洋ごみ対策として，回収処理および発生抑制対策，実態把握，国際連携に総合的に取り組んでいる。海岸漂着物処理推進法については，2018 年 6 月に一部改正され，マイクロプラスチック対策が法律に初めて盛り込まれたほか，各種規定が追加された。また，循環基本法に基づく第四次循環型社会形成推進基本計画が同月に閣議決定され，「プラスチック資源循環戦略」を策定する旨が同計画に盛り込まれた。環境省としては，海洋ごみ問題の解決に向け，改正海岸漂着物処理推進法等に基づき，国内における各種対策および国際連携・協力をより一層推進していきたい。

Recycling Laws and Their Evaluation in Japan
AI summary Read the abstract
Japan's suite of recycling laws — covering packaging, appliances, vehicles, construction materials, and food waste — is reviewed alongside the emerging microplastics problem and Japan's policy responses to it. The paper highlights that existing recycling frameworks were not designed with microplastics in mind, creating regulatory gaps that need to be addressed as plastic debris increasingly fragments into microscale particles.
Avoiding Land-based Plastic Pollution, including Microplastics
AI summary Read the abstract
This Japanese-language policy paper outlines Japan's approach to preventing land-based plastic pollution, including microplastics, in the context of the 2022 UNEA resolution to develop a global plastics treaty. Japan's domestic framework includes monitoring, source identification, biological impact assessments, and the 2022 Plastic Resource Circulation Promotion Act, which addresses plastic across the full lifecycle. The paper emphasizes Japan's role as an advanced nation in waste management and its ongoing commitments to international plastic pollution reduction.
