The primary body of water surrounding Japan is the Pacific Ocean. Japan is an island nation located in East Asia, consisting of four major islands—Honshu, Hokkaido, Kyushu, and Shikoku—along with numerous smaller islands. The geographical position of Japan along the Pacific Ring of Fire makes it prone to natural phenomena such as earthquakes and tsunamis. The ocean influences Japan's climate, resources, and economy significantly, particularly through fishing and maritime trade.
