Japanese Jucheism

Japanese Jucheism is a civically authoritarian, economically ,  culturally variable, and  nationalist ideology based off the platform of the General Association of Korean Residents in Japan.

Beginnings
In the late 40's,  made its way to the  Japanese populace, especially among Zainichi Koreans. Kim Il Sung later called on the Zainichi Koreans to strive for a revolution in Japan and  South Korea. In 1955, the General Association of Korean Residents in Japan (Japanese: 在日本朝鮮人総聯合会, Korean: 재일본조선인총련합회) or more commonly known as Chongryon (총련) or Chōsen Sōren (朝鮮総連) was formed.

Paradise on Earth
In the late 50's, Chongryon launched a campaign to relocate Zainichi Koreans back to North Korea, under the campaign of 'Paradise on Earth'. The campaign lasted until the late 80's, with approximately 87,000 Zainichi Koreans and 6,000 Japanese spouses relocated to North Korea. According to a defector, who was relocated on the behalf of the 'Paradise on Earth' campaign, many opted to return to Japan as they believed that they were lied to. However, they were subsequently placed in prison camps by the North Korean government.

Espionage activities
Some Japanese Jucheists were coordinating with North Korean spies in espionage activities, such as handing out forged Japanese passports. Many North Korean spying activities were traced back to Chongryon, which denied their involvement.

Park Chung-hee assassination attempt incident
On 15 August 1974, the 29th anniversary of the South Korean independence day, Park Chung-hee held a speech on the National Theater of Korea. Mun Se-gwang, a Zainichi Korean, was convinced by Chongryon to assassinate Park Chung-hee to 'fuel the need of a revolution' in South Korea. Mun missed his shots, injuring himself and killing Park Chung-hee's wife, Yuk Young-soo.

The incident caused relations to sour between Japan,  North Korea and  South Korea. South Korea temporarily cut off ties with Japan, condemning Japan's laxed enforcement against Chongryon. The official stance of the South Korean government on the incident is that Mun was acting in behalf of Chongryon, in which the Japanese government denies the South Korean government's official stance. The official stance of the North Korean government on the incident was that they were never involved in the assassination attempt, although they praised Mun as a "true communist".

This was, until Park Geun-hye, Park Chung-hee's daughter, visited North Korea, where  Kim Jong Il admits North Korea's involvement in the assassination attempt and subsequently apologized.
