The Potential and Challenges of Rare Earth Mining at Minamitorishima: Can It Strengthen Japan's Economic Security?

China has been tightening its restrictions on rare earth exports, leading to widespread impacts such as temporary suspensions of automobile production in Japan, Europe, and the United States. While countries are working to secure alternative sources of rare earths outside China, growing attention has turned to Japan’s easternmost territory, Minamitorishima, and its potential for rare earth mining. Can extraction at a remote island located far from the mainland, at depths of 6,000 meters beneath the seabed, succeed? To what extent could it contribute to reducing dependence on China? This paper examines the challenges and prospects for commercialization of rare earth mining in the Minamitorishima area.

The importance of shipping routes thrown up by the Panama Canal

The Panama Canal, located in Central America and connecting the Pacific and Atlantic Oceans, has attracted much attention in recent years. In addition to U.S. President Trump's insistence on the "return of the Canal," abnormal weather and other factors have caused the water level of the Canal to drop, affecting logistics in Japan and other parts of the world. An examination of the problems posed by the Panama Canal suggests to us that it is important not only to stabilize the water level of the Canal, but also to establish safe navigation throughout the world.

Soft Recognition: Enabling Participation of Self-Determination Groups in Intergovernmental Organisations

Soft Recognition: Enabling Participation of Self-Determination Groups in Intergovernmental Organisations

This report examines the interrelationship between international affairs and domestic politics. In today's globalized world, challenges such as climate change, migration, and pandemics transcend national borders and influence domestic issues across countries. The report specifically focuses on "soft recognition" mechanisms that enable self-determining groups to participate in intergovernmental organizations, exploring both the benefits this participation offers and its potential for conflict resolution. The findings provide valuable insights for states and multilateral organizations alike.
