The Jeju Teachers' Association and Jeju Island Office of Education also proposes a visit to Japan to learn about their lives in connection with Korean schools in Japan. In 2020, Jeju National University and Ritsumeikan University plan to have the opportunity to jointly study and research the lives of Koreans in Japan from the standpoint of peace and human rights education. Based on the opinions of these international researchers, we should cover the human rights abuses committed under the US military administration and the responsibility for the deaths under US military influence, even after the establishment of the Korean government, and to restore the honor of 4.3 victims and survivors to prevent this from happening again. This is to protect peace and human rights in Jeju and the Korean peninsula.
