The authors has written this book with the conviction that the "East Sea" and the "Sea of Japan" should be used together. Professor Soh Jeong-Cheol has collected old maps from the last 1960s to the 1990s. Then he joined the Society for East Sea and continued his research. In the early days, he thought that the "East Sea" was the right name and it should be used on maps in place of the "Sea of Japan." However, he gradually changed his mind: as the "Sea of Japan" has recently come into more frequent use and is supported by vested interests, it would be more rational to those with the "East Sea."

To this end, the authors studied the notations and the sea between Korea and Japan on maps of many countries of the world and attempted to relate the truths about the "East Sea/Sea of Japan" as objectively as possible.
