Japan–South_Korea_Joint_History_Research_Project
At the Japan-ROK Summit Meeting held in October 2001, then Prime Minister Junichiro Koizumi and then President Kim Dae Jung agreed on creating a team of experts regarding Japan and Korea's relationship in history. In May 2002, Japan and South Korea brought together expert historians from both nations in order to "promoting mutual understanding concerning accurate facts and recognition of history."[1] Initially, multiple experts from each country would compile and translate multiple sources for validity and accuracy. "The experts of Japan and the ROK have conducted joint research through a number of period-specific working groups: ancient history, medieval and modern history, and modern and contemporary history."[1]
As the research progressed multiple disagreements were slowly being resolved toward accurate facts by both historians. Two very important points one of which was resolved was 4th century Japanese history and modern history.
