NAHF published 『Grandfather Yoon Young-ha shouting ‘Dokdo’ in Osaka』. This year, Shimane Prefecture of Japan is holding the so-called Takeshima Day event and promoting public opinion by claiming wrong sovereignty over Dokdo. At this time, we published a book about the story of Yoon Young-ha, a Korean-Japanese man who enthusiastically campaigned for Dokdo in Osaka, informing the serious harm caused by the so-called Takeshima Day.

Yoon Young-ha(1926) was born during the Japanese colonial period and lived as a Korean in Japan after liberation. So he began the Dokdo movement with a desire for a future in which the people of both Korea and Japan live like friends. This book introduces Yoon Young-ha's ideas and activities on Dokdo. It also tells how serious Japanese provocations are, such as the so-called Takeshima Day event and the description of Dokdo in Japanese textbooks. It also contains why the Japanese government's claim to Dokdo is wrong.
