The symbol in the centre of the "Hi-no-maru" (日の丸, the Japanese national flag) is the state "Mon" or emblem. It has been the state symbol of Japan for centuries. The flag became the National Flag following the Meiji Restoration in 1868. It never had rays.

While Album des pavillons [pay00] gives the Pantone color as red 186C, I have a fabric sample on file which suggests the use of Pantone 193C.

Historical Information

From: Japan: an illustrated encyclopedia Vol. 2 (M-Z):

national flag

(kokki). The national flag of Japan has a crimson disc, symbolizing the sun, in the center of a white field. It is popularly known as the Hinomaru (literally, "sun disc"). It is said that at the time of the Mongol Invasions of Japan (1274 and 1281) the priest Nichiren presented a sun flag to the shogun. The Tokugawa shogunate (1603-1867) adopted the flag for its ships in the early 1600s. In the mid-19th century the shogunate decreed that all Japanese ships fly flags with the sun on a white field. In 1870 the Meiji government officially designated it for use on Japanese merchant and naval ships. It has never been officially designated as the national flag; however, it has become so by customary use. The "rising-sun" flag with 16 rays used by the former Japanese navy and by the present Maritime Self-Defense Forces is a military service flag and should not be confused with the national flag.

Beside a drawing of the flag is the following text:

The design and proportions of Japan's national flag were fixed in 1870 by the Meiji government. The vertical to horizontal ratio was set at 2:3, the disc was to be placed at the exact center, and the diameter of the disc was to equal three-fifths of the vertical measurement of the flag.

The name of Nichiren means the sun and lotus in English (Nichi = Nihon = the sun; Ren = lotus ) and the lotus is a typical symbol of Buddhism. That is why he gave the sun (and lotus) to the Shogun who at that time was politically opposed to the Emperor (who was a God in Shintoism). Nichiren is said the greatest Buddhist in Japan because a majority of Japanese are not Shintoist but Buddhist. The Nichiren was formed his organization which is now called Soka-Gakkai whose political part is Komei-tou which is composed of the present Japanese cabinet.
I think he believed his flag could help the Shogun, who had military power, to save Japan and the people from Mongol Invasion. He could not find any reason for him to give his flag to the Emperor who is believed the God and son of the Sun but who had no ability to defeat Mongolian.

Nichiren's purpose was to motivate the political powers to abandon the more popular Buddhist sects and to accept the Lotus Sutra as the one sure way to save Japan. His was a religious and philosophical movement, not a political one. At the same time he issued to the government a treatise entitled "Rissho Ankoku Ron" which predicted great disaster for Japan should they not retreat from the heretical (popular) Buddhist sects and accept his teachings.

At http://www1.jca.apc.org/anti-hinokimi/archive/chronology/senzen/ (a Japanese language webpage) there is a chronology of the history of Japanese flags, anthems, et cetera, based on contemporary official documents.

A few interesting things:

• On June 13, 1870, the Army "National Flag" was gazetted as a 16-ray Rising Sun flag, 4 feet 4 inches by 5 feet, with the centrally-located sun disc one-third the width of the flag. There was no fringe.
• On October 27, 1870, The Navy "National Flag" was gazetted as the Hinomaru, 7 feet 8 inches by 11 feet 7 inches, with the centrally-located sun disc three-fifths the width of the flag. The Jack was the same, but in 6 feet by 8 feet. Also gazetted were the flag of the Emperor and the flag of the Imperial Family, shown as the Emperor's Flag, 1870-1879 and Royal Family, 1976 (Family). Dimensions same as the "National Flag". These flags lasted until October 8, 1889, when the current set of flags were adopted.
• On July 30, 1912, to mark the passing of Emperor Meiji, the Hinomaru was required to have a strip of black cloth flown above it, as well as a black cloth to cover the flagpole's ball finial.
• On March 25, 1931 the Imperial Diet attempted to legislate the Hinomaru as the official National Flag and also its official specifications; it passed the House of Commons, but did not go through the House of Peers.

National Flag at the London 2012 Olympics

The protocol manual for the London 2012 Olympics (Flags and Anthems Manual London 2012 [loc12]) provides recommendations for national flag designs. Each NOC was sent an image of the flag, including the PMS shades, for their approval by LOCOG. Once this was obtained, LOCOG produced a 60 x 90 cm version of the flag for further approval. So, while these specs may not be the official, government, version of each flag, they are certainly what the NOC believed the flag to be.
For Japan: PMS 032 red.

The Prime Minister's Proclamation No. 57 issued on January 27 in the 3rd Year of Meiji (1870):

1. The national flag:

This shall not be removed and even a ferryboat shall keep it hoisted.
Hoist it at 8 a.m. every morning and haul it down at sunset every evening. In case of non-hoisting of the national flag it is customary of the international law that no plea is justified it treated as pirates.

2. The dimensions of the national flag:

The ratio of the hoist and fly 7:10.
The diameter of the disc: three fifths of the hoist length of the flag locating in the center.

Regulated as above for strict observances.

Law Information

Posted at https://groups.io/g/flags/files/J/JP/jp-Japanese-Flag-Laws.1870-2005.pdf is "Japanese flag Laws from the official gazette1870-2005", dated 2021-05-30, by Nozomi Kariyasu (15 December 2023): "I have listed all of the flag-related laws from the official bulletins and laws and regulations from the establishment of the Meiji government to the end of World War II discovered in the National Diet Library Parliamentary Archives."

The date of adoption for the naval jack was on October 3rd, 1870 (Meiji 3) and it was from Prime Minister's Proclamation No. 651. The law shows the flag ratio was 2x3 and also has the sun-disc as 3/5th of the hoist of the flag. The position of the sun-disc is placed in the center. This pattern is the exact same as the current national flag.

Recently, I discovered a Japanese flag imposed with writing on it on Yahoo Auctions. The auction mentions the text imprinted on the flag is the lyrics of Kimi ga Yo, the Japanese national anthem. I have seen this as patches and stickers, but this is the first time I have actually seen it on cloth.
