Vexillology (from the Latin vexillum, a flag or banner) is the scholarly study of flags, including the creation and development of a body of knowledge about flags of all types, their forms and functions, and of scientific theories and principles based on that knowledge. Flags were originally used to assist military coordination on the battlefield, and have evolved into a general tool for signalling and identification, particularly identification of countries.

Heraldry encompasses all of the duties of a herald, including the science and art of designing, displaying, describing and recording coats of arms and badges, as well as the formal ceremonies and laws that regulate the use and inheritance of arms. The origins of heraldry lie in the medieval need to distinguish participants in battles or jousts, whose faces were hidden by steel helmets.

The tradition and practice of heraldry in Poland dates from the 13th century. Although influenced by French and German heraldic practice, differs in a number of respects. One of the most striking is that a coat of arms does not belong to a single family. Many, sometimes hundreds of unrelated families may use a single coat of arms. Each coat of arms also has its own name. One side-effect of this unique arrangement was that it became customary to refer to members of the nobility (Polish: Szlachta) by both their family name and the name of their coat of arms.

The national flag of Japan is a white flag with a large red disc (representing the rising sun) in the center. The flag's official name in Japanese is Nisshōki (日章旗, "sun flag") but the flag is more commonly known as Hinomaru (日の丸, "sun disc"). The Hinomaru was widely used on military banners in the Sengoku (Warring States) period of the 15th and 16th centuries. During the Meiji Restoration the flag was officially adopted for use as the civil ensign by Proclamation No. 57 on February 27, 1870 (January 27, Meiji 3 in the Japanese calendar). However, the flag was not adopted nationally until August 13, 1999, by the Law Regarding the National Flag and National Anthem.

Along with the national anthem Kimi ga Yo, the Hinomaru is considered a controversial symbol of the militaristic past of the country. Use of the Hinomaru was also severely restricted during the early years of the American occupation of the country after World War II, although restrictions were later relaxed. Japanese law did not designate any particular flag as the national flag from 1885 until 1999, although the Hinomaru was legally the national flag for the brief period from 1870 until 1885. Despite this, several military banners of Japan are based on the design of the Hinomaru, including the sun-rayed Naval Ensign. The Hinomaru was used as a template to design other Japanese flags for public and private use. ( more...)
