"島" (shima) is the Japanese word for "island." It refers to a landmass that is surrounded by water. Islands can vary in size, from small rocky outcrops to large landmasses like 本州 (Honshu), which is the largest island of 日本 (Japan). Islands can be found in oceans, seas, rivers, and lakes. Islands can be formed through various geological processes, such as volcanic activity or the rising of land above sea level. They often have unique ecosystems and can be home to diverse wildlife. Some famous islands include ハワイ (Hawaii) and グリーンランド (Greenland), each with distinct cultures and environments.
