(Stripes Japan)
Called “hinomaru” (circle of the sun) or “nisshoki” (sun-mark flag), the national flag of Japan is a white rectangle with a red circle in the center. The flag has embodied Japan’s other name, "The Land of the Rising Sun." Keeping with the theme, the sun is important in Japan’s native religion, Shintoism, and the emperor is considered a direct descendant of the sun goddess in the mythology.
