This report is about the idea of Hekiun Okuhara which appeared in 「Hanjyoyoin poetry」 of 『Takesima and Ulleung island』. This book looks like objective geographical book. But the aggressive idea of Hekiun appeared in here and there. He said this poetry is the collection of inspection groups of Dokdo. But truly it includes Korean’s poetry such as Kim kuang ho and Sim hung taek, who isn’t the member of inspection group. Also it contains imaginary people’s poet. Editor used such imaginary names to secure objection.「The rock」and「The pine tree」appeared in Japan’s poetry mean the eternity of emperor. The word like 「The rock root」used in 「Hanjyoyoin poetry」, means the root is very strong, so it is never pulled out eternally. Therefor the meaning of planting pine tree in top of the Dokdo is a part of ceremony which prayer the endless rule of Japanese emperor in the new territory.
