Ikeda’s Official Letter
Mr. Ikeda Juzaburo(池田十三郎), chief of the Administrative Bureau of Communications of the Japanese Resident-General, sent Korean Ministry of Interior an official letter of inquiry, asking for the clarification of the names of towns and titles of villages and the year/month of establishment of Uldo County, which was branched out of Samcheok County, Gangwon-do.
Note that article says Mr. Ikeda asked about the towns and villages of “Uldo County”, not “Ulleung Island”. As we have already found, the article in the Korean newspaper, Hwangseong Shinmun (皇城新聞) on a same day reported that the Korean ministry replied that the county was established on October 25, 1900, and that the neighboring islands were Jukdo (竹島) and Seokdo (石島), or rocky island Jukdo (竹島石島). The Korean ministry also gave the dimensions of Ulleungdo as sixty ri from east to west and forty ri from north to south for a total of 200 ri. This left “Dokdo” outside of the County, meaning Korean government set Takeshima/Dokdo outside of their territory.
Pro-Korean claim that this dimension is for the solo island of Ulleungdo, not Uldo County, however, it is extremely unnatural to answer the area/dimension of sole island when you are asked about the Uldo County. Moreover, it almost coincides with the areas given by Lee Geon-ha(李乾夏), a Minister of Internal Affairs of Korea, who submitted the petition for the ordinance in the Imperial Edict which made Ulleungdo a County of Gangwon Province (大韓勅令第41号) in 1900. It is apparent that Korean government at the time didn’t even hint that they considered Seokdo(石島) in this Edict was today’s Dokdo(独島) as they suddenly started to claim around 1969.
When Korean central government finally received the report from Gangwon Province governor and Chunchon county magistrate Lee Myung-rae (江原道觀察署理・春川郡守 李明來), who originally received the report about "Dokdo", which locates 40km in the open sea(外洋百余里) away from Ulleungdo, becoming Japanese territory from the county magistrate Shim Heung-taek(沈興沢), Minister of Interior Lee Jee-yong（内部大臣 李址鎔) and Prime Minister Bak Che-soon (議政府参政大臣・朴齋純） ordered governor Lee to investigate the "circumamstances of the island in concern and the activity of Japanese on the island" by the "Directive no. III (指令第三号)" on 20th May.
If Korean government found out that Shim’s “Dokdo” was appended island of Ulleungdo and “Seokdo” in Ordinance 41 in 1900 was another name of the island, they must have answered “竹島独島(JukdoDokdo)”, instead of “竹島石島(JukdoSeokdo)”, in the reply letter to the Resident-General, who asked about the towns and villages of “Uldo County”, not “Ulleung Island”.
From those articles, it is apparent that Korean government then didn’t consider Dokdo/Takeshima as their territory, and technically, that means they officially acquiesced the Japan's sovereignty over Takeshima/Dokdo by not interpolating "Dokdo" in the answer to claim the sovereignty.
