The documents of Chosentsusinshi between Japan and Korea was designated as a UNESCO World Heritage site 4 years ago. But the designation as a UNESCO World Heritage site is New Beginning Not the End, we should keep in mind to discover the new documents and materials. The Chosentsusinshi Framed Picture of Kameyiin(亀井院) was discovered newly at Takisannji(瀧山寺) of the old temple of Okazaki City of Aichiken of Japan, 3 years ago(2018). Kameyiin was one of many tatchūs(塔頭) in Takisannji. Takisannji has been existed from 7th century. The Framed Picture was writing by Lee Sam Seok(李三錫) of the 7th Chosentsusinshi delegation by analysis. After 90- years, the Framed Picture of Chosentsusinshi was discoverd in Aichiken newly. It was guessed such as receiving from Chosentsusinshi by the chief priest of Seiryuin(青龍院) serving with Takisannji headmaster during Edo period. On the one hand, Framed Picture of Kochuzi(廣忠寺) of Okazaki City was disclosed such as Sakai Tadazumi(酒井忠 恭) of Himezi Lord(姫路藩主) in 2020. That item was supposed the Framed Picture of　Kim Sibok(金時璞) of the 8th Chosentsusinshi delegation until this very day. Kochuzi of Okazaki City was built to commemorate his father called Matsudaira-Hirotada(松平廣忠) by Tokugawa Ieyasu(徳川家康). The Framed Picture of Kochuzi was changed in 1752. The unfixed Framed Picture of Kochuzi was missing, the genuine writing of Kim Sibok was remained such as a scroll. The box of the scroll was decorated by Aoi-Mon(徳川家紋の葵紋), and was filed with the documents called the memoir receiving by the 6th Shogun Tokugawa Ienobu(徳川家宣). The genuine writing of Kim Sibok was confirmed by his seal, but we should examine several issues such as the connection of Kochuzi and Shogun's family, and the reason of the changing Framed Picture by Kochuzi(廣忠寺) etc. Especially One citizen called Oda Akie(小田章恵) played an very important role of precious discover in Takisannji and Kochuzi at this time. When we have to open the Chosentsusinshi documents of UNESCO World Heritage Site to much more people, not blocking between professional researcher, the significance of the World Memory of UNESCO would be expanded. The role of grassroots researcher would be expected very much.
