Although he came from such an unfavorable background, Arima was able to secure admission to the 12th class of the Imperial Japanese Naval Academy, after graduating from the forerunners of Doshisha University and Keio University with degrees in English language. Arima was assigned as a sub-lieutenant to the three-masted corvette in 1885 and graduated 16th out of 19 cadets from the Navy Academy in 1886 after ''Tsukuba'' made a long distance navigational voyage from Japan to Newcastle, Sydney, Wellington, Fiji, Samoa, Honolulu, Apia and Pago Pago lasting most of 1886. On graduation, Arima was assigned to , followed by the gunboat in 1889. His subsequent military service included both sea and staff assignments.〔Evans, David ''et al.'' (1997).

He was sent back to sea on the from 1894-1895 during the First Sino-Japanese War, and was Chief of Staff of the Yokosuka Naval District from 1895-1896. From 1896, he held the prestigious post of Aide-de-camp to Emperor Meiji and was promoted to lieutenant commander in 1897 and to commander in 1899. From March 1900, Arima was assigned as chief navigation officer to the flagship of the Imperial Japanese Navy, the battleship , on which he again visited England in 1902. After his return to Japan, he was promoted to the position of executive officer on the cruiser , but at the end of 1903, he was reassigned to the staff of the IJN 1st Fleet. In 1903, Commander Arima developed a military strategy which considered attrition as an element of overwhelming force in warfare; and this analysis caught the attention of Admiral Tōgō Heihachirō in the period shortly before the outbreak of hostilities in the Russo-Japanese War.〔Connaughton, Richard. (1991). ( ''The War of the Rising Sun and Tumbling Bear,'' p. 35. )〕 During the Russo-Japanese War, he received his first command, that of the cruiser . Following his promotion to captain in July 1904, he captained the cruiser , during the Battle of the Yellow Sea. During the war, Arima was the senior member of Tōgō's Combined Fleet staff.〔Evans, ( p. 89. )〕 One of the architects of the plan to blockade the Russian Pacific Fleet in Port Arthur (which he had visited on his return to Japan from England the previous year), Arima was on two of the three missions, and personally commanded the failed Second Port Arthur blockade attempt, during which Commander Takeo Hirose was killed.〔 page 39〕 Soon afterwards, he was reassigned from his field command to become commandant of the Takeshiki Guard District on Tsushima, where he remained for the rest of the war.〔( Axis History Factbook ): (IJN, Takeshiki ).〕 After the end of the war, he again received a field command, and from 1906–1907, was captain of the cruiser . He subsequently became Chief of Staff for Fleet Admiral Baron Ijuin Gorō, commander of the IJN 2nd Fleet from 1907 – 1908.〔Axis: (IJN, 2nd Fleet )〕 From 1908 to 1910 he was Commandant of the Naval Gunnery School at Yokosuka, Kanagawa.〔Axis: (IJN, Naval Gunnery School ).〕 Arima was promoted to rear admiral on December 1, 1909. He served as Chief of First Bureau (Operations) on the Imperial Japanese Navy General Staff from 1910 to 1912 and at the end of 1913 was promoted to vice admiral.〔Axis: (IJN, 1st Bureau ).〕 From 1914 to 1916, he was Commandant of the Imperial Japanese Naval Academy, continuing to influence its curriculum heavily towards the ''kantai kessen'' theory which he had helped create.〔Axis: (IJN, Naval Academy ).〕 He also sat on the Board of Inquiry for the Siemens scandal, a political scandal involving naval procurement in 1914. After serving briefly as Director of the Naval Education Command, he became commander-in-chief of the IJN 3rd Fleet from 1917 to 1918.〔Axis: (IJN, 3rd Fleet ).〕 He was promoted to full admiral on November 25, 1919. He then served as Director of Naval Education Command from 1919 to 1920.〔Axis: (IJN, Naval Education ).〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Arima Ryōkitsu」の詳細全文を読む スポンサード リンク
