The National Flag of Japan

This is the flag of Japan. The national flag of Japan is a white rectangular flag with a large red disk (representing the sun) in the center. This flag is officially called Nisshōki  in Japanese, but is more commonly known as Hinomaru 日の丸。 The Nisshōki flag is designated as the national flag in Law Regarding the National Flag and National Anthem, which was promulgated and became effective on August 13, 1999. Although no earlier legislation had specified a national flag, the sun-disc flag had already become the de facto national flag of Japan. Two proclamations issued in 1870 by the Daijō-kan, the governmental body of the early Meiji Era, each had a provision for a design of the national flag. A sun-disc flag was adopted as the national flag for merchant ships under Proclamation No. 57 of Meiji 3 (issued on February 27, 1870), and as the national flag used by Navy under Proclamation No. 651 of Meiji 3 (issued on October 27, 1870). Use of the Hinomaru was severely restricted during the early years of theAmerican occupationafter World War II, although restrictions were later relaxed. 
In early Japanese history, the Hinomaru motif was used on flags of daimyos and samurai. During the Meiji Restoration, both the sun disc and the Rising Sun Ensign of the Imperial Japanese Navy became major symbols in the emerging Japanese empire. Propaganda posters, textbooks, and films depicted the flag as a source of pride and patriotism. In Japanese homes, citizens were required to display the flag during national holidays, celebrations and other occasions as decreed by the government. Different tokens of devotion to Japan and its emperor featuring the Hinomaru motif became popular during the Second Sino-Japanese War and other conflicts. These tokens ranged from slogans written on the flag to clothing items and dishes that resembled the flag.
