Fact in Senkaku and Diaoyutai islands I tell about a conclusion first in Nagoya-shi educational group house on July 13th in 1997. It's about the Senkaku (Diaoyutai) islands which become peace with Japan and China, tension and the focus, but I have to put it in order accurately from a relation with China, Ryukyu, Satsuma, Edo "and" Tokyo from 400 years before to 100 years before. In conclusion Senkaku (Diaoyutai) islands are a Chinese territory. I'm thinking but the 21st century is decided(1) Taiwan, Chinese continent(2) Jeju Do and Korean Peninsula(3) are, in what kind of situation there is "Daiwa Tokyo political power" with Okinawa-shoto, and that these area and Far East Asia are peaceful or that I contract. We'll assume that I think in the different lecture about Taiwan and Jeju Do, and I narrow down to Senkaku (Diaoyutai) islands and think. From 1 point 600 year-400 years before, a fishing island and Kitakojima. A general term in Oki Minamiiwa, Oki Kitajima, Koubishou and Sekibishou "Diaoyutai islands" was a desert island, but a Chinese name was on, and there was recognition as a Chinese territory China and Ryukyu Kingdom in Shogunate Government of Edo and Tokyo government (until the Meiji). 2 About a Japanese name in "Senkaku" islands. The meaning that it was acute. But neither Kohjien nor "dictionary of classical Chinese explained in Japanese" have a word to say as "Senkaku". It's indicated on Kohjien as Senkaku-shoto. I find out that "Senkaku" is a coined word from here. United Kingdom navy warship Semarang measured fishing islands in 1845, and a fishing island was similar to a steeple in a Christian church, so the etymology of "Senkaku" called Pinncle (pinnacle) Islands and announced it as a chart in 1855. The Sea of Japan an army translated that with "Senkaku archipelago" "acute 緒嶼" in 1890 (1890) year, and it was called "Senkakurettou" as the name 1900 (1900) age Hisashi Kuroiwa lumped together. There are "Senkaku islands" at Uotsurishima, Minamikojima, Kubashima and Taishoujima for the present Japanese name. The Tokyo government which won Sino-Japanese war (Japan) is doing "possession resolution" by a cabinet meeting just before the Nissin peace treaty conclusion and is doing neither an official announcement of possession nor advertisement under the DOSAKUSA for making the Diaoyutai islands which were a Chinese territory since 3 Japan territory. Ishigaki-shi made the one on which Japanese Government is insisting as 識杭 of possession at present "Yaeyama Senkaku archipelago" in 1969 on May 5th from left side on the rectangular stone, and 識杭 which listed Uotsurishima, Kudakashima, Taishoujima and pinnacle 緒嶼 from the right by vertical writing, and cut Shimana with "Ishigaki-shi Tateshi" was built in the bottom. This isn't an act of Ryukyu government (Okinawa-ken) and Tokyo government (Japanese Government). 1.4 Chronological table. 1879 (1879) year Series of measures toward Ryukyu domain by the Meiji administration and Okinawa-ken formation The inside life which is a field survey in Okinawa-ken from Tsutomu Lord within the (1885) year 1885 -28 (1894-95) year in 1894 Sino-Japanese war 1894 (1894) year Classified document 1895 when the conventional notes to the Minister of Foreign Affairs are exceptional from the Secretary of State for the Home Department (1895), annual order which builds 年識杭 (in February Okinawa-ken) and 1900 going not to have been made public and to have admitted a 13th number of 1896 (1896) age Okinawa-ken NO area organization NI barrier SURU matter firman to Yaeyama-gun Yaeyamashotou Senkakurettou (without mentioning in Senkakurettou) in Yaeyama-gun (1900) In Hisashi Kuroiwa "Senkakurettou", a general term and a magazine "earth science", thesis. 2.5 Toshio Okuhara work "Senkakurettou and territory attribution problem". - "The center-lessness place, it's occupied, when, the international law top doesn't always require procedure such as the bulletin of endorsing it by the Cabinet and a regular admission by a domestic law for proof of state possession will existence. When I have it even in the territory merit by 先占, when an important thing is effective rule, and state possession will is proved through the fact, it's enough,", "When it's possible to prove that a state sovereignty generally came even if I don't even come to realistic occupation when a natural environment in Senkakurettou and the resident aptitude-lessness are considered, they can insist on Japanese territorial rights to a chain of islands on the international law sufficiently." 10th number of the "morning sun Asian review" "Senkakurettou special story February in 1972" This Okuhara thesis is speaking for an idea of Japanese Government and a practical effect ruler vividly.
