Profiles of Adaptation: Japan

Japan utilizes the 2018 Climate Change Adaptation Act and a revised 2021 plan to coordinate adaptation across ministries using 66 Key Performance Indicators. Domestically, the country employs local adaptation centers in 38 of 47 prefectures and the A-PLAT information platform to support municipal planning. Internationally, Japan provides technical expertise in disaster risk reduction, manages the Asia-Pacific Climate Change Adaptation Information Platform (AP-PLAT), and has committed to doubling adaptation finance to approximately $14.8 billion between 2021 and 2025.

• The Climate Change Adaptation Act of 2018 established the legal basis for Japan's adaptation efforts, requiring a Climate Change Adaptation Plan that is updated every five years. The revised plan approved in October 2021 utilizes a 'Plan, Do, Check, Act (PDCA)' management approach and 66 Key Performance Indicators (KPIs) to monitor sectoral and fundamental progress.
• Japan supports locally led adaptation through municipal and prefectural climate change adaptation centers, which were active in 38 out of 47 prefectures as of April 2022. To facilitate this, the Adaptation Information Platform (A-PLAT) consolidates climate risk data for use by local governments in formulating adaptation plans.
• The Ministry of Economy, Trade, and Industry (METI) promotes international adaptation businesses in seven specific areas: sustainable energy supply, food security and agricultural production, health and sanitation, climate monitoring and early warning, secure resources and sustainable water supply, resilient infrastructure against natural disasters, and climate change finance.
• Japan provides global technical and financial assistance, including the 2021 launch of the Asia-Pacific Climate Change Adaptation Information Platform (AP-PLAT) and a commitment to increase adaptation finance to approximately $14.8 billion from public and private sources between 2021 and 2025. In March 2022, Japan contributed $6 million to the adaptation fund.
• Japan applies its Disaster Risk Reduction (DRR) expertise internationally through projects such as the implementation of erosion-control dams in Indonesia and a flood-resilient subway system in Bangkok, Thailand.
