Japan (Japanese: 日本国; Nihon-koku or Nippon-koku) is an island country in East Asia. Located in the Pacific Ocean off the northeast coast of the Asian mainland, it is bordered on the west by the Sea of Japan and extends from the Sea of Okhotsk in the north to the East China Sea in the south. The Japanese archipelago consists of four major islands—Hokkaido, Honshu, Shikoku, and Kyushu—and thousands of smaller islands. The capital of Japan and its largest city is Tokyo; the Greater Tokyo Area is the largest metropolitan area on Earth. Japan is divided into 47 administrative prefectures and eight traditional regions. About three-quarters of the country's terrain is mountainous and heavily forested, concentrating its agriculture and highly urbanized population along its eastern coastal plains. The country sits on the Pacific Ring of Fire, making its islands prone to destructive earthquakes and tsunamis.
Political System
Japan is a constitutional monarchy and a sovereign state whereby the power of the Emperor is limited. As a ceremonial figurehead, the Emperor of Japan is defined by the constitution to be "The Symbol Of The State And Of The Unity Of The People." Executive power is wielded chiefly by the Prime Minister and his cabinet, while sovereignty is vested in the Japanese people. Japan's legislative organ is the National Diet, a bicameral parliament; It consists of a lower House of Representatives with 465 seats, elected by popular vote every four years or when dissolved, and an upper House of Councilors with 245 seats, whose popularly-elected members serve six-year terms. There is universal suffrage for adults over 18 years of age, with a secret ballot for all elected offices. The prime minister as the head of government has the power to appoint and dismiss Ministers of State, and is appointed by the emperor after being designated from among the members of the Diet.
Military
Japan Self Defense Forces (自衛隊 Jieitai), JSDF, also referred to as the Self-Defense Forces (SDF), Japan Defense Forces (JDF), or the Japanese Armed Forces, are the unified military forces of Japan that were established in 1954 and are controlled by the Ministry of Defense. The JSDF consists of three branches: JMSDF (Japan Maritime Self-Defense Force), JASDF (Japan Air Self-Defense Force) and JGSDF (Japan Ground Self-Defense Force).
The country's military is restricted by Article 9 of the Japanese Constitution, which renounces Japan's right to declare war or use military force in international disputes; it prevents Japan from researching and manufacturing offensive weapons. Nevertheless, an amendment would later be written in the constitution thus enabling Japan to participate in existing conflicts. Despite being branded as a "Self-Defense Force," the JSDF ranks among the top 10 strongest military on Earth.
Geography
Japan spans over an archipelago of 6852 islands covering 377,975 square kilometers (145,937 sq. mi); the five main islands are Hokkaido, Honshu, Shikoku, Kyushu, and Okinawa. The Ryukyu Islands, which include Okinawa, are a chain to the south of Kyushu. The Nanpō Islands are south and east of the main islands of Japan.
Because of its mountainous terrain, approximately 67% of Japan's land is uninhabitable. The habitable zones, mainly in coastal areas, have extremely high population densities. As of 2014, approximately 0.5% of Japan's total area is reclaimed land.
Tokyo is Japan's capital and largest city; other major cities include Yokohama, Osaka, Nagoya, Sapporo, Fukuoka, Kobe, and Kyoto.
Japan is the primary location of the Gate, leading to the Special Region.
Notable Citizens
- Tarō Kanō – The Japanese Minister of Defense and Itami's old friend. Like Itami, he is also an otaku. Strong-willed and patriotic, he succeeds Prime Minister Morita as an interim candidate after he and the other Cabinet members expose Morita's cowardice in intending to surrender administration of the Gate to a foreign international conspiracy instead of defending his nation's sovereignty. At the end of the series, he has retired from politics and thus become free to pursue his otaku passions once more.
- Reiko Shirayuri – Prime Minister Motoi Shinzō's aide who later becomes Senior Vice Minister for Problem Measures regarding the Special Region under Prime Minister Morita.
- Kōji Sugawara – A Ministry of Foreign Affairs official who is sent to the Special Region as an ambassador to the Empire as part of a delegation to convince the Empire to seek peace with Japan. When he meets Sherry Tyueri and she falls in love with him, he is quite awkward about her affection for him considering her tender age, but genuinely cares about her. When Zorzal takes over the throne and his Oprichnina arrests members of the nobility who seek peace with Japan, he saves Sherry by declaring that she is his fiancé. Before the Gate is closed, he decides to remain in the Special Region to maintain the diplomatic ties between Japan and the Empire.
- Kōichirō Hazama – A JSDF Lieutenant General in charge of the JSDF task force within the Special Region who holds Itami in high regard despite the latter's reckless attitude. As a responsible commander, he is one of the JSDF servicemen who stays behind when the Gate is shut down.
- Akira Yanagida – A First Lieutenant who serves as General Hazama's aide. He dislikes Itami due to the latter gaining his rank due to the Ginza Incident, whereas he had to earn it by hard work himself. Unlike Itami, who cares about the people of the Special Region and wants to help them, Yanagida sees no problem in manipulating and exploiting the Special Region's people and resources for Japan's gain. He eventually develops a grudging respect for Itami despite the fact that the two seem to antagonize each other over minor details, especially regarding Itami's nonchalant attitude and his ability to gain allies so easily.
- Shunya Kengun – A JSDF colonel and commander of the Special Region Task Force's 4th Combat Unit, an air assault company, and a veteran of the first battle of Italica and the evacuation of the Jade Palace. Despite their age difference and language barrier, he begins a relationship with Rose Knight Beefeater E Caty, and is one of the servicemen remaining in the Special Region after the Gate's collapse.
- Akira Kamikoda – A somewhat hot-blooded lieutenant colonel in the Japanese Air Force, and the leader of the JASDF branch of the Task Force, flying a F4 Phantom. He stays in the Special Region upon the Gate's closure because of the lack of flying restrictions in that world, and because of his romantic attentions towards the Rose Knights.
- Nyutabaru – A major and chief of the JSDF detachment stationed in Akusho, the Imperial Capital's red-light district.
- Osamu Higaki – A major in the Special Region Task Force and Itami's immediate superior, who is usually frustrated by Itami's lax attitude violating military protocol.
- Yōji Itami – Itami is a 33-year-old otaku and JSDF soldier. After successfully escorting hundreds of citizens to safety during the attack on Ginza, Itami is promoted to the rank of first lieutenant and tasked to investigate the world on the other side of the Gate as commanding officer of the Third Recon Unit. He is a certified JSDF Ranger and Special Forces commando (although this only occurred due to his superiors' futile attempts to discipline him), and while he is notable for being a slacker and a fast runner from trouble, he is honest and compassionate and can be quite capable when under stress. He is also later rendered immune to bodily harm due to a contract Rory Mercury makes with him, in exchange for him becoming her servant upon his death. With his heroic acts during the battle of Ginza and in the world beyond the Gate, he also becomes a role model for his fellow JSDF soldiers and his friends in Alnus Town.
- Shino Kuribayashi – A petite but buxom Sergeant First Class of the Third Recon Unit under Itami, she does not hold him in high regard due to his otaku nature. She idolizes the Japanese Rangers and Special Forces; a perception which is somewhat broken when she learns that Itami is a certified member of both. She excels in hand-to-hand combat and prefers charging head-first into a battle to take on her opponents with just her rifle-mounted bayonet. She remains in the Special Region when the Gate is closed, because the new world presents her with a chance to cut loose with her combative nature and because she has fallen in love with her teammate Tomita, despite him being already involved with Bozes of the Rose Knights.
- Akira Tomita – Sergeant First Class Tomita, a 27-year-old trained Ranger, is the gentle giant of the unit who is a solemn but kind man and often acts as the voice of reason within the group. He and Bozes enter a relationship, and as a result he is one of the JSDF servicemen remaining in the Special Region when the Gate is closed.
- Takeo Kurata – A 21-year-old sergeant in the JSDF and driver on the recon team, he is also an otaku like Itami, with a special fetish for catgirls. His geeky fantasy becomes reality when he meets Persia, a housemaid of the Formal Clan who happens to be half-cat. The two become close very quickly and are nearly inseparable whenever Kurata visits Italica. Owing to this affection, Kuruta is one of the JSDF servicemen who voluntarily stays in the Special Region when the original Gate is shut down.
- Mari Kurokawa – The medic of the Third Recon Team with the rank of Sergeant First Class, at 190cm she is an unusually tall woman. Her father is a submarine commander in the Japan Maritime Self-Defense Force. She can be uncomfortably sharp-tongued in her opinions at times, especially to Itami if she suspects he has ulterior motives related to his otaku hobbies. While she cares for the well-being of those under her supervision, especially civilians, she can be very vicious with disobedient patients, often using means of intimidation bordering on sadism to discipline them. At the end of the series, she has returned to Earth and become head nurse of the JSDF Central Hospital.
- Sōichirō Kuwahara – A fifty-year-old Sergeant Major who serves as Itami's second in command. As the oldest member in the unit, he has experience and wisdom of training and leading recruits on the field. He replaces Itami as team leader after the latter runs off to kill the Fire Dragon on his own and is consequently relieved of his command. After the original Gate has closed, he retires from the JSDF and works at a security firm while spending time with his newly-born grandchildren.
- Hitoshi Furuta – A leading private in the Third Recon Team who used to work in his family's first-class restaurant until he got into an argument with the new management, and joined the JSDF to gather the funds to open his own restaurant. During the team's mission in the Imperial Capital, he goes undercover as a chef after his cooking gets the interest of Prince Zorzal. There he falls in love with Tyuule, Zorzal's Warrior Bunny concubine and secret adversary; they end up aiding each other in thwarting the tyrannical prince, and after Tyūle's death and the closure of the Gate, he and Delilah open a restaurant in Tokyo in her memory.
- Hideyo Komakado – A leading member of the Japanese Defense Intelligence Headquarters and later of the Public Security Division, who acts as a guide and head of personal security during the official visits of Itami's troupe in Japan. Later he proves instrumental in deposing Prime Minister Morita for conspiracy against Japan's national interests and installing Minister Kanō as an interim candidate in his place.
- Noriko Mochizuki – One of several Japanese civilians who were captured by Imperial scouts prior to the Ginza Incident. She was taken to the Imperial capital, where she became Prince Zorzal's sex slave. When the JSDF learn of Noriko's presence, they rescue her and warn the Empire there will be consequences if all other Japanese slaves are not repatriated. Despite her traumatic experience and the loss of her entire family during the Ginza Incident, she returns to Alnus to act as a liaison between the locals and the Japanese media. After witnessing the callous sensationalist pursuits of the Japanese media in the Special Region (especially as personified by Kazunari Komurazaki), she begins to crusade against this bias, determined to serve only the truth to the Japanese public.
- Nanami Kuribayashi – Shino's younger sister and a rookie newscaster. After she finds out that the news concerning the Special Region are censored by elements in the Japanese government looking out for their own interests instead of the public's, she dedicates herself to relaying the pure truth about the other world and root out the corruption in the Japanese media. After the closure of the Gate, she establishes a popular online news studio.
- Kazunari Komurazaki – An extremely arrogant, superficial Japanese journalist who constantly tries to score negative press about the JSDF in the Special Region solely for publicity's sake. His selfishness and recklessness endanger and even cause the death of some of his support personnel in his sensationalist pursuits, making him very unpopular with the Japanese on-site.
- Risa Aoi – Itami's ex-wife and a yaoi doujin artist whose hobby of collecting dolls leave her broke quite frequently. Having been former classmates in college, she and Itami married for convenience: Itami provided money for Risa's hobby and Risa looked after the household for Itami. Risa divorced Itami after she tried to convince Itami not to go to the Special Region and realized that he never really loved her. Nevertheless, they still care about each other, with Itami still providing financial support to Risa. Risa still loves Itami, even though she knows he'll never realize it on his own. After encountering Piña, she becomes the princess' main source for doujin manga.
