Japan is an island nation in East Asia. The country was formerly a member of the Axis Powers of World War II before being defeated by the United States and remade as a thriving democracy and major economic power. The nation has maintained a unitary constitutional monarchy with an emperor and an elected parliament. In 2018, under threat of annihilation and with overwhelming hostile forces amassing near its border, Japan is forced to join the Greater Korean Republic.
Beginning in 2014, Japan embraced a rise of nationalism in the face of the unified Greater Korean Republic. Japanese-American foreign relations deteriorated in which Japan and the U.S. accused each other of unacceptable imposition of duties on imports in order to protect respective domestic industries. The inability to find common ground sharing the burden of their military alliance in an apparent new era of East Asian peace consequently ended it permanently two years later.
Over the ages, Korea and Japan have had continuous racial tensions, stemming mainly from the Japanese invasions of Korea in the 16th and 20th centuries and the harsh regime the Japanese imposed upon Korea from the beginning of the 20th century to the end of World War II. These widespread feelings of mutual resentment and occasionally outright hatred escalated to breaking point following an alleged assassination attempt by Korean agents on the Japanese royal family. Although a statement from Japan's intelligence agency Naicho indicated that the prime suspects were reactionary nationals, the general public blamed the so-called "North" Korean secret agents. As a result, violent protests and riots broke out and attacks were made on residents, with shops being owned by ethnic Koreans broken into and in some cases set on fire.
In 2017, the Korean government demanded international condemnation against Japan at a United Nations meeting in Brussels, presenting circumstantial but compelling evidence that despite official Japanese condemnation of the riots, Japanese police were involved in the systematic murder of ethnic Koreans. Such demands availed Korea little, despite unofficial estimates of as many as 12,000 Koreans being slaughtered in a series of violent attacks in Japan that forced many of the surviving Korean residents to flee.
In April 2018, Kim Jong-un, enraged at the world's idleness as Koreans were slain simply due to their heritage in Japan, declared a "heavenly mandate" to protect Koreans worldwide and the GKR declared war on Japan, citing lack of action from the United Nations and the international community over the last seven months even as the Korean death toll mounted. In the brief invasion, Korean forces took many "strategic targets" and destroyed the Chugoku nuclear power plant to show resolve, killing thousands of lives instantly and laying a death sentence on countless others. Many cities and towns were evacuated to avoid the radiation, and Korean Special Forces took over 26 nuclear plants, most near metropolitan areas. The international community condemned the incursion by Korea into Japan, calling the actions a "war crime" and "an act of terror"; however, many nations were unable to respond, citing domestic issues. After much destruction, including the ravaging of Japan's southern coast, and with Korean forces advancing on Tokyo, the Japanese Diet passed an emergency measure, acceding to all of Kim Jong-un's demands, and Japan surrendered to the Greater Korean Republic "without firing a single shot".
Several months after the war, the United States called for sanctions against the Greater Korean Republic's occupation of Japan. Korea in return mocked America's inability to gain the respect of the rest of world due to its increasing powerlessness to provide food and heat to its citizens, calling such sanctions "hypocritical" and blamed the U.S. for "the spread of chaos and discord around the globe", such as in the Middle East.
The United Nations, led by the U.S., shortly afterwards passed a non-binding resolution condemning the recent destruction of a Japanese nuclear power plant by the Korean military as a human rights violation, with 46 votes in favor and 11 against. Most of the countries that voted against the resolution, mostly Asian neighbors of the GKR, have provided Korea with material support and were suspected of holding closed-door trade discussions with the East Asia power. Korea responded by pulling its envoy from Brussels and disengaged from the entire body.
In 2019, French authorities presented evidence at the U.N. that revealed the GKR secretly creating nuclear weapons by using existing Japanese infrastructure, with the said missiles based on an American-made ICBM peacekeeper. In 2024, the GKR launched the next generation of navigational satellites from the Kagoshima Space Center in the Kagoshima Prefecture on the southern tip of Japan. It is likely that the satellite containing the weapon that would create the EMP attack on the U.S. was launched from this site as well. Since the occupation, Japan's forces are now a major part of the Korean military, most likely in charge of the robotics, the space agency and the nuclear weapons. It is also mentioned that the "liberated Imperial Japanese Navy" helped the People's Navy of the GKR transport vehicles and troops and materials for Operation Water Snake to Los Angeles.
In Homefront: The Voice of Freedom, it is mentioned that around 2019, after Japan was absorbed by the GKR, prison camps were established and Yi Dae-Hyun was promoted to a role overseeing public executions in Japan, which he earned his code name "Salmusa".
It is most likely that Japan has a resistance group similar to that of the American Resistance. It was mentioned that there was a rebellion in the Northern Prefectures of Japan against the GKR in 2022, though as of 2025, Japan continues to remain firmly under Korean control.
