Flag of Japan

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 the 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 the American occupation after World War II; these restrictions were later relaxed.
