Tuvalu, a country comprising nine coral islands that dot the South Pacific, is known as a vulnerable country in terms of sea-level rise which is said to be caused by global warming.The damage caused by beach erosion that one of the islands is already submerged is extremely grave, however, it appears this is no longer a problem that can be resolved by Tuvalu alone.The fearful cries of small islands floating in an endless sea are Earth's own cries.

Japan is a maritime state and an island nation, however, it makes no sense at all that this is undiscerned by the public.The shift away from the ocean of the Japanese is notable despite their geographic and historical ties to the ocean.Additionally, I would say there is great significance in the role of the island in terms of the exclusive economic zone.Is it not very necessary to take another good look at the ocean and the island based on a far-sighted policy?

The ocean, a new frontier, is a three-dimensional space.People are prone to regard its planar breadth, however, we should pay more attention to the wondrous world below the water's surface for the future.We should consider the need to apprehend the UNCLOS-established exclusive economic zone spatially towards development and environmental conservation.I'd like to draw attention to the ocean water and see the various aspects of Japan's jurisdictional waters and its position in the world.
