Recognized as a regional model for water and ocean governance, the Partnerships in Environmental Management for the Seas of East Asia (PEMSEA) evolved from a long-running project-based entity into a self-sustaining international organization with legal personality with a mission to foster and sustain healthy and resilient coasts and ocean, communities, and economies at regional, national and local levels across the East Asian Seas (EAS) through integrated management solutions and partnerships under the framework of the Sustainable Development Strategy for the Seas of East Asia (SDS-SEA) that 14 countries in the EAS region have adopted.

Future oriented (marine) zoning maps, which are the result of marine spatial planning, will not only be useful for fair and efficient responses to new uses such as offshore wind power generation, but after the BBNJ Agreement comes into effect and protected areas are established in the areas beyond national jurisdiction it will also be necessary for considering consistency with the zoning maps of countries with adjacent EEZs. In order to discuss the use and conservation of the entire world's oceans on an equal footing with other countries, it is hoped that Japan will also engage in marine spatial planning that includes its EEZ.

Larike Village, located in Indonesia, is renowned for its unique conservation efforts, particularly the protection of its giant eels. The Larike Village Giant Eels Protected Area is an example of community-based conservation, where local communities play a crucial role in preserving biodiversity and promoting sustainable development.

It is important for Pacific Small Island Developing States (PSIDS) to realize the transition to renewable energy. In the Pacific Islands, there is great potential for ocean thermal energy conversion (OTEC), which takes advantage of the ocean's characteristics, but in the short term the need is clear for distributed renewable energy sources_ including OTEC, such as solar and wind power, as well as batteries, in what might be called the "PALM hybrid model." Sharing Japan's "technology, know-how, and funds" is the key to solving the issue of development costs.
