Study on a "communist organization" the Buraku Liberation League
The Buraku Liberation League as a Communist
A japanese history researcher "Sukeyuki Morooka" wrote the Buraku Liberation League (BLL) Headquarters Journal "Liberation Newspaper". The BLL is known for being hostile to the Japanese Communist Party (JCP). But the BLL is not hostile to the JCP due to anti-communism. According to Sukeyuki Morooka, the BLL is a communist organization different from the JCP. Morooka's book "Postwar Buraku Liberation Controversial History" (Sengo buraku kaihō ronsō shi) is as follows.
The controversy over China and the Soviet Union is clearly projecting over the assessment of the international situation. The Communist Party who straddles the central headquarters of the BLL can fully appreciate that the Communist Party of China and Zennosuke Asada(朝田善之助) and others rely on the assertion of the Soviet Communist Party. (p.23)
In 1979 the former USSR National Security Committee (KGB) Major Stanislav Lechchenko pointed out that Takumi Ueda(上田卓三), BLL Former President was a member of the Soviet Spy collaborators within the Socialist Party of Japan in his book. He announced that Ueda was called Uranus.   
Relationship between the BLL and North Korea
As it is not well-known, the BLL has maintained close relations with Kim Il Sung and Kim Jong Il's two generations of North Korea since 1985. After Saichiro Uesugi(上杉佐一郎) became BLL President in 1982, the BLL began to emphasize international activities with anti-discrimination international movement, but the exchange with North Korea was part of that.
In late May 1985, 7 heads of the BLL including Uesugi visited North Korea for the first time. The visiting team had taken sightseeing exclusively around Kim Il-sung's birth place, the Juche thought tower, Panmunjeom, museums and art galleries, watching theater, watching the movie "Kim Jong Il secretary" over about a week, We have talks with Nisshu and participating in the Juche idea learning society.
In June 2002, the BLL also sent a visiting team headed by President Shigeyuki Kumisaka(組坂繁之). Approximately 3 months before Mr. Kumisaka and his colleagues visited North Korea, the former wife of the Yodo hijacker testified in court that he abducted Keiko Arimoto to North Korea. Since then the interest in the abduction issue in Japan has been rapidly rising. Also, in May, just before the visit, the incident that North Korean refugees' families rushed to the Japanese Consulate General in Shenyang, China is a big problem. It is a remarkable new place that the circumstances of the domestic situation in North Korea be repeatedly reported by the press with these opportunities. It is rarely heard, such as voice that praises North Korea like that of 1985.
But the BLL was different. Mr. Kumisaka's greeting in the Joseon Dialogue Association said that "I was able to realize the visit of the Democratic People's Republic of Korea in a memorable year when Kim Il-sung's main birthday 90 years, General Kim Jong Il will be 60 years old I thank you from the bottom of my heart, "I have begun with tribute to Kim's son as usual.
