Amateur Radio Call Signs Of Japan
Call signs in Japan are unique identifiers for telecommunications and broadcasting. Call sign blocks for telecommunication The International Telecommunication Union has assigned Japan the following call sign blocks for all radio communication, broadcasting or transmission: While not directly related to call signs, the International Telecommunication Union (ITU) further has divided all countries assigned amateur radio prefixes into three regions; Japan is located in ITU Region 3. The ITU and CQ Magazine have divided these regions into zones. The main islands of Japan are in ITU Zone 45 and CQ Zone 25. Outlying islands can have differing zones, see the following table: Amateur radio callsign areas In Japan, amateur radio (ham radio) licensing of operators is regulated by the Ministry of Internal Affairs and Communications (MIC, 総務省 Sōmu-shō) with the Japan Amateur Radio League (JARL, 日本アマチュア無線連盟) acting as a national amateur radio organiza ...

International Telecommunication Union
The International Telecommunication Union is a specialized agency of the United Nations responsible for many matters related to information and communication technologies. It was established on 17 May 1865 as the International Telegraph Union, making it the oldest UN agency. The ITU was initially aimed at helping connect telegraphic networks between countries, with its mandate consistently broadening with the advent of new communications technologies; it adopted its current name in 1932 to reflect its expanded responsibilities over radio and the telephone. On 15 November 1947, the ITU entered into an agreement with the newly created United Nations to become a specialized agency within the UN system, which formally entered into force on 1 January 1949. The ITU promotes the shared global use of the radio spectrum, facilitates international cooperation in assigning satellite orbits, assists in developing and coordinating worldwide technical standards, and works to improve tele ...

Hokkaido
is Japan's second largest island and comprises the largest and northernmost prefecture, making up its own region.

Call Signs
In broadcasting and radio communications, a call sign (also known as a call name or call letters—and historically as a call signal—or abbreviated as a call) is a unique identifier for a transmitter station. A call sign can be formally assigned by a government agency, informally adopted by individuals or organizations, or even cryptographically encoded to disguise a station's identity. The use of call signs as unique identifiers dates to the landline railroad telegraph system. Because there was only one telegraph line linking all railroad stations, there needed to be a way to address each one when sending a telegram. In order to save time, two-letter identifiers were adopted for this purpose. This pattern continued in radiotelegraph operation; radio companies initially assigned two-letter identifiers to coastal stations and stations onboard ships at sea. These were not globally unique, so a one-letter company identifier (for instance, 'M' and two letters as a Marconi station ...

Historically, Japan was divided into a number of provinces called ''koku'', which were in turn classified according to both their power and their distances from the administrative center in Kansai. Under the latter classification, most provinces are divided into , , and . Therefore, one explanation is that ''Chūgoku'' was originally used to refer to the collection of "middle countries" to the west of the capital. However, only five (fewer than half) of the provinces normally considered part of Chūgoku region were in fact classified as middle countries, and the term never applied to the many middle countries to the east of Kansai.
