Regions, Prefectures and Overseas Territories of Japan


The Japanese Empire is structured in regions (地方), prefectures (mostly 県) and overseas territories (庁) to allow for ease of administration. Although the Empire is a unitary state, the prefectures are permitted to directly elect their governor and a unicameral local legislature. Many functions have delegated to these prefectures to be administrated locally, however, the central government in Tokyo gives many guidelines for policy and ultimatively has the power to reorganise or abolish the prefectures if it so wishes, without interference by the local level. Prefectures do not have a constitutional guaranteed existence. Regions are groups of prefectures and do not have any administrative function. They are mostly just perceived divisions in Japan's natural, cultural and political geography. Overseas Territories are territories that belong to Japan, yet are not considered part of the "Inner Territories" and do not have prefecture status. These administrative units are ruled by a governor chosen by the central government.

South Qechua Territory (Minami-Kechua-chō) (lost to Tianxia)

Karafuto Territory (Karafuto-chō) (elevated to Prefecture)



  1. Hokkaidō is a prefecture-level administrative unit, but does not carry the description "prefecture" (県), instead using the historical term "circuit" (道) already in its name.
  2. Tōkyō is a special prefecture-level administrative unit that is descriped as "metropolis" (都) instead of "prefecture", due to its importance.
  3. Kyōto and Ōsaka are prefecture-level administrative units using a special character (府) instead of the one for "prefecture", but their transliteration is the same. This character is used to denote urban centres of special importance.

This factbook, as well as my RP uses Japanese name order as a standard when rendering Japanese (and generally Asian) names. Thus, the given name follows the surname. e.g. Konoe Nobuhisa carries the surname Konoe and the given name Nobuhisa. Please keep that in mind, unless you want to be rude and address people with a completely unjustified intimacy.


Important Characters


Konoe Household


Konoe Nobuhisa


The honourable Konoe Nobuhisa is the de facto head of state of Japan, overseeing it in the Emperor's stead. Appointed by Yuan Jia I, Konoe Nobuhisa tries to act as a non-partisan arbiter in national politics and he distances himself from the political factions that compete for power in national politics. As the head of the Konoe clan and leading figure in the home rule movement, Konoe enjoys much respect by the ordinary Japanese and is generally judged favorably. Still, behind the scenes, Konoe is also willing to take a stance, should it be necessary to curb radical tendencies. His wife, Konoe Sanae (née Honda) has died shortly after the birth of their daughter Sakuya and he aims to raise their daughter to be a proper woman.


Konoe Sakuya


Being the daughter of the Governor-General, Sakuya is a young woman that draws society's attention. She was raised as a proper young Japanese woman, though, as the sole daughter of the current head of the Konoe clan, expectations for her to do something meaningful are high.


Unafiliated Northern Clique


Nakamichi Minoru


Second Prime Minister of Dai-Tōhoku and first Prime Minister of Japan, Nakamichi has become a colourful person in Japanese politics. As a central character in the Hoshutō he became Minister of Foreign Affairs and established the basis of the nation's foreign affairs. With the fall of the Minshutō from power, Nakamichi became prime minister for three terms, before he stepped back in the wake of the Fuso incident. Still, he remains part of the upper echelons of the Kokumin Hoshutō and it is unclear what his political future might be.


Hagane no Dōmei


Date Seiranko


A former naval officer, mayor of Sendai, Miyagi and leading figure in the Kokumin Hoshutō, Date is one of the most important members of the so-called Northern Clique. She has personal contacts to the Konoe household through their common activism for an independent Japan and it was her political influence that brought Nakamichi to the Hoshutō's forefront. Currently, she serves as the Minister of the Navy, in charge of a major part of the armed forces. Seiranko also claims to be the head of the Date clan. Her character is marked by a certain adherance to traditional values, but also an assertiveness and aggressiveness when it comes to her political aims. She had lost her position as Minister of the Navy after the Carrier Incident, but was reinstated by Akiyama, during the time immediatly before the Japanese-Commonwealth War. Date is the head of the informal Hagane no Dōmei, a militaristic national conservative faction among the party.


Akechi Mitsuki


As the Minister of Foreign affairs, Akechi was Nakamichi's successor, though most people would agree that her diplomatic skills are far below those of Nakamichi. Her rather forceful and aggressive approach to the nation's diplomacy is close to Date's way of thinking, altough she is not part of the original Northern Clique. Instead, Akechi has earned her position more by rallying Chūbu region nationalists to the conservative cause. Still, many think, Akechi should not be underestimated, especially given her potential to cause damage. After the Carrier Incident, she was purged and is now only appointed as occasional ambassador to other countries, posts she receives mostly due to her old connections. Still, with Japan rising, even Akechi senses a possible return as possible.




Akiyama Kagami


Akiyama Kagami comes from a rather affluent household in Akita and is part of the Northern elite that rules the Japanese Empire. Although being of the Second Generation of the Northern Clique, after the dissolution of Japanese home rule for several years due to the Carrier Incident, Akiyama rose to power as an obscure "moderate conservative" and restored the power of the Kokumin Hoshutō. However, despite her reputation as prudent and moderate politician, Akiyama's policies to reign in military and intelligence apparatus have contributed more to her own power base as Prime Minister than to the peace in the region. Still, as the victor over the American Commonwealth, akiyama is popular and despite her eccentric character, Akiyama's influence grows by the day. Akiyama also heads the Fuyokai, a small group of politicians that aim for closer relations with Korea and restoration of Imperial rule.


Tsukino Aoko


One of Akiyama Kagami's most loyal followers and friends, she has been instated as chief of the National Intelligence, heading the Central Intelligence Research Agency and reporting directly to the Prime Minister. Most people consider her Akiyama's lapdog and call her Hachikō, after the other loyal Akita inu, though less affectionate than for the real dog.


To be expanded


Note: This is important for my RP, not necessarily important politically for the nation. Many important people will not be here, some people here may be politically of lesser or even negligible importance.

The Japanese Military / Nihongun (日本軍)


The Japanese Military Forces (or Nihongun) are the armed forces of the Japanese Empire and responsible for a vast array of tasks. The Military has been established in Genkai 5 as a successor to the Renpōgun, the military forces of the Dai-Tōhoku Renpō, established in Genkai 1. The mission of the military has up to now been redefined twice (in Genkai 5 and Genkai 13) and currently lists the following as the purpose of the Japanese Military Forces:

  • Safeguarding the political sovereignity and territorial integrity of the nation, as well as protecting its citizens from foreign aggression.
  • Assisting civil authorities in relief operations in the aftermath of natural or man-made disaster.
  • Assisting the Japanese law enforcement in keeping public order and safety at the request of the Prime Minister.
  • Supporting allied nations in defense of their sovereignity, territorial integrity and vital national interests.
  • Securing and defending the vital national interests of the Japanese nation.
  • Engaging in peace-keeping missions to strengthen global stability.

The Japanese Military has as nominal commander-in-chief the Prime Minister of Japan, but is usually administered by the responsible ministries and their general staffs. For coordination between the two ministries and their three staffs, there exists the Joint Chief-of-Staff Council (Tōgō Bakuryō Kaigi). Overall control over funding, deployment and the ability to wage war is checked by the National Diet.




The administration of the Japanese Army (Nihon Rikugun) and the Japanese Airforce (Nihon Kūgun) is responsibility of the Ministry of Defense (Bōei-shō), which manages the procurement, logistics management, finances and personel managment of these two branches. It also has for military intelligence the Defence Intelligence Headquarters (Jōhōhonbu) and for policing of its forces in the field, the Military Police (Keimutai).




The Ministry of the Navy (Kaigun-shō) is responsible for the administration of the Navy and its respective sub-services. It originally was established as a government agency during the time of Dai-Tōhoku, but has been elevated to Ministry level during the establishment of the Japanese Navy. It thus also has its own intelligence service, the Naval Intelligence Bureau (Kaigun Jōhōkyoku), and it's own police force, the Naval Police (Kaigun Keimutai).


Despite the organisation in two seperate ministries, there are several services that are centralised to improve cost-efficiency, cooperation and to limit factionalism between land-based and naval forces. These include the Technical Research and Development Institute for advanced weapons research and development, the National Defense Academy for basic officer training of all branches and the National Intelligence Academy, which is the centralised training institute for the Defense Intelligence Headquarters, the Naval Intelligence Bureau and the Central Intelligence Research Agency. Naval Officers however are required to take one additional year of training at Etajima Naval Academy.


The Ministry of Defense is located in Ichigaya, Shinjuku, slightly detached from most of the other ministries. The Ministry of the Navy has been reconstructed closer to other government agencies and is located at next to Hibiya Park, Chiyoda.
