NAHF hosted an at the Seamark Hotel with The Society for East Sea on 18–19 September. The purpose of this seminar is to spread the Sea Name, which is called 'East Sea', to the international community, and it is an annual academic event held with experts and related scholars in the field of geographic names in each country. This year's theme was 'Geographical Naming in the Digital Era', and five overseas scholars were able to participate in real time through online platforms.

The development of digital technology and the spread of mobile devices have a great influence on the environment using geographic names and the production of maps. In this seminar, we sought how to utilize these changes to resolve the old conflict over "how to mark the East Sea waters".

Joseph Stoltmann(Professor of University of West Michigan, former president of the American Geographical Teachers Association) has announced how the notation of the geographic name under digital technology can contribute to historical and geopolitical discourse, especially the proposal to write the East Sea and the Sea of Japan together side-by-side. In addition, Gerry O'Reilly(Professor of Dublin City University, Political Geographer) presented the process of changing the way the East Sea waters are written on digital, and the future direction. Kim Yeong-hun(Professor of the Korea National University of Education) has presented the specificity of a geographical name that can contribute to solving issues about the mark of the East Sea in the digital age. In addition, Cho Tae-young(Secretary General of NAHF), Joo Sung-jae(President of the Society for East Sea), Park No-hyung(Professor of Korea University School of Law), Jung Jae-jeong(Emeritus Professor of University of Seoul), Yoo Ui-sang(former Ambassador for Geographic Naming), and Japanese journalists in Korea participated as presenters and panelists.

In this regard, the proposal of 'write the East Sea and the Sea of Japan together side-by-side', which is receiving the response of the world, seems to be a new turning point.
