Japan is an archipelago consisting of four main islands located in East Asia. It has a population concentrated on the eastern coasts facing the Pacific Ocean and is subject to natural disasters such as volcanoes, earthquakes, and typhoons. Traditionally, Japan had a feudal system with local lords and an emperor, and was influenced by religions like Buddhism, Shintoism, and Confucianism. After World War 2, Japan adopted Western influences while maintaining traditions, and its technology-focused economy has made it a global leader with one of the highest standards of living, though it now faces issues from urbanization and an aging population.
