Kang was born in Pyongyang, North Korea, and spent his childhood there. He had a good relationship with his grandfather. He had a happy childhood.[1] His family lived in relative luxury from his grandfather's position and the fortune that he had given to the country upon the family's return from Japan. Though they had never renounced their North Korean citizenship and Kang's grandmother had been a staunch party member in both countries, Kang has stated that the family remained under a cloud of suspicion for having lived in Japan.
Concentration camp
Kang's autobiography describes a brutal life in a North Korean prison. Death from starvation or exposure to the elements was common, with routine beatings and other punishments. His education consisted almost solely of memorizing the sayings and speeches of Kim Il-sung; at 15, his education ceased and he was assigned to exhausting and dangerous work details, and was made to view public executions. He said of the camps, "It was a life of hard labour, thirty percent of new prisoners would die. And we were so malnourished, we would eat rats and earthworms to survive."[2]
There was an order by Kim Jong-il that those in the prison with relatives in Japan had to be released after 10 years. In the mid-1980s North Korea depended heavily on foreign currency remittances. Many Zainichi Koreans or Koreans living in Japan were sending remittances to North Korea. Such people opposed the imprisonment of their relatives in North Korea. The amount of remittances being sent from Japan to North Korea deteriorated due to the wave of mass imprisonment. As such Kang was permitted to be released from prison after serving his 10-year sentence. Once he left the camp, he was sent to live in Yodok village. He could not go all the way back to Pyongyang, but he moved to Pyongsong, near Pyongyang. He moved in with his uncle who was working at the National Science Research Institute in the city.[3]
Release
In 1992, Kang and An Hyuk escaped from North Korea by crossing the Yalu River into China.[4] In late 1992, Kang arrived in South Korea and moved to the capital Seoul.
Kang has not been in contact with his family since he defected. In 2011, it was assumed that his sister, Mi-ho, and her 11-year-old son are in Yodok concentration camp, having been sent back there as retaliation for Kang's defection.[11]
