Seo Jeong-cheol et al.: Whose sea is the East Sea?

*Whose Sea Is the East Sea?* is a research book crafted through over 40 years of tenacious pursuit by authors who were the first in Korea to research and raise the issue of the East Sea's name. The designation "East Sea" carries complex and multifaceted implications, ranging from political disputes over national territory and economic issues related to resource development to Korea's diplomatic standing in the international community. Therefore, the book reveals the truth through over 100 ancient maps serving as decisive evidence, ranging from De Fer's *East Asia*, which identified the East Sea as a Manchu place name over 2,000 years old, to Takahashi Kageyasu's *Shinjo Mankoku Zenzu*, which labeled the Pacific Ocean as the Great Sea of Japan. Part 1 of this book explains the present and history of the East Sea, the interests of nations, a topographical analysis of names related to the East Sea and the Sea of Japan, the sea's international status, and the evolution of its name within the history of map development. Part 2 examines the designations of the East Sea by various countries using a double helix approach. Part 3 presents criticisms of Japan's biased research on the name of the East Sea and reasons for opposing the exclusive use of the name "Sea of Japan" through papers related to the naming of the East Sea. Emphasizing that complex real-world problems cannot be solved by emotion alone and require cold reason and logical grounds, this book proves the historical legitimacy of the name "East Sea."
