Japan consists of over 6,800 islands with a mountainous landscape that is heavily forested. It has an extremely high population density and is located in the Pacific Ring of Fire, giving it over 100 active volcanoes and the highest natural disaster risk worldwide. The national identity draws from traditions like geisha, samurai, and kimono. The language uses kanji characters from Chinese but is unrelated, and has no pluralization or articles. Shinto is the indigenous religion that worships nature. Gender roles are still somewhat influenced by Confucian ideals with expected marriages and household duties. Art forms include anime, manga, kabuki, and vocaloid music.
