After the war, Korean-Japanese literatures can be divided into the following three eras: 1. Until the independence day of Korea from the day the loss of Japan. 2. Until ‘disperse of private war’ in 1955 from ‘Joseon war.’ 3. After forming ‘The pro-Pyeongyang federation of Korean residents in Japan.’ In the first era, Korean-Japanese remained in Japan wrote some amateur literatures, such as Inminmunwha, Corea-munye, Jokukmunkak, Josen, Jamin, Joreonmunwha, Gunkuk in order to celebrate the independence of their mother land, Korea. And then nationalistic newspapers Hebangsunmun, Joseon-sinbo were published. On Joseon-sinbo, Kim Dal-soo argued that literatures written in Japanese language by Korean authors should be considered Korean literatures rather than Japanese literatures. Moreover, Minju-Joseon was published. On 1947, February 20th, the artists from both Jochongnyeon and the Federation of Korean Residents in Japan formed Korean-Japanes federation of culture association together. On 1948, January17th, Korean-Japanes literary society which was formed by uniting each association shared some parts of the code of conduct as Joseon writers alliance which was formed on 1945, December 13th. These show the Korean-Japanese humanities scholars’ tendency in the era. In the second era, Korean war occurred in 1950, May. As the result of this, Nam-ro party led by Park Heon-young got arrested. After that incident, bias took place in the media, Nodongsinmun and Minju-Joseon; they didn’t fully cover the process of Park Heon-young’s case in the court. On the other hand, Motherland defense national committee’s Sin-Joseon published by Korean Resident in society fully covered the case in 1953 and 1954. Nothing is certain, but their intension of the full coverage which had been exposed Korean-Japanese people can be speculated that they wanted people from Nam-ro party to give up their thought. In the third era, forming Jochongnyeon in 1955 was a turning point in the ideology of Korean-Japanese activists. Korean-Japanese people started to be recognized as citizens from the republic, thus, their identity as residents in Japan got weakened; they started to feel more connected to their own country. As a result, this incident caused a big impact on the literature. After that, betrayal and commercial papers are becoming problems to the humanities scholars.
