The national flag of Japan is a white rectangular flag with a large red disk (representing the sun) in the center as its mentioned in Japan flag map. This flag is officially called Nisshōki (日章旗?, "sun-mark flag") in Japanese, but is more commonly known as Hinomaru (日の丸?, "circle of the sun"). 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.

Passed in 1870, the Prime Minister Proclamation No. 57 had two provisions related to the national flag. The first provision specified who flew the flag and how it was flown; the second specified how the flag was made. The ratio was seven units length and ten units width (7:10).The red disc, which represents the sun, was calculated to be three-fifths of the total size of the hoist length as you can see in Japan flag map. The law decreed the disc to be in the center, but it was usually placed one-hundredths (1/100) towards the hoist. On October 3 of the same year, regulations about the design of the merchant ensign and other naval flags were passed. For the merchant flag, the ratio was two units length and three units width (2:3). The size of the disc remained the same, however the sun disc was placed one-twentieth (1/20) towards the hoist.

Issued by the Japan Defense Agency (now the Ministry of Defense) in 1973 (Showa 48), specifications list the red color of the flag as 5R 4/12 and the white as N9 in the Munsell color chart. The document was changed on March 21, 2008 (Heisei 20) to match the flag construction with current legislation and updated the Munsell colors. The document lists acrylic fiber and nylon as fibers that could be used in construction of flags used by the military. For acrylic, the red color is 5.7R 3.7/15.5 and white is N9.4; nylon has 6.2R 4/15.2 for red and N9.2 for white as its shown in Japan flag map.
