The was a fleet of the Imperial Japanese Navy. It was the main combat fleet of the Japanese Navy and formed the core of a wartime Combined Fleet organization. It was created from the Standing Small-Fleet in 1889. It was split into the 1st Fleet and the 2nd Fleet in 1903.
On 24 July 1889 the Fleet Ordinance (Edict No. 100) was enacted as the first independent fleet-related decree of the Japanese Navy, and the fleet was to be composed of three or more warships. On 29 July 1889 the Standing Small-Fleet was reorganized into the Standing Fleet (commander-in-chief: Rear Admiral Inoue Yoshika).
On 19 June 1894, in response to the deterioration of Japan-China relations, all fleet regulations were revised (Edict No. 71), and torpedo boats and transport vessels were attached to the fleet as specified by the Edict. The edict also stipulated that the staff should be enhanced and that ships could be dispatched outside the patrol areas. On 13 July a Guard Fleet consisting of nine outdated ships and small ships with a flagship Katsuragi was formed, and soon after on 19 July it was renamed the Western Sea Fleet. On the same day a Combined Fleet was formed by the Standing Fleet and the Western Sea Fleet. The commander-in-chief of the Combined Fleet was also the commander-in-chief of the Standing Fleet, Vice Admiral Ito Sukeyuki, and the staff of the Combined Fleet was also the staff of the Standing Fleet.
After the end of the First Sino-Japanese War the Combined Fleet and the Western Sea Fleet were disbanded on 15 November 1895. On 14 October 1897 the Fleet Ordinance was amended (Edict No. 356) to allow the fleet to consist of two or more warships, including torpedo boat division, mine laying division, and transport vessels. A chief of staff position was also created at this time.
On 10 March 1903, during the 4th Great Navy Exercise, the 1st and 2nd Fleets were temporarily formed, and on 10 April 1903 after the exercise, a fleet review ceremony was held off the coast of Kobe. On 28 December 1903 the Standing Fleet was disbanded and permanently divided into the 1st Fleet and the 2nd Fleet. The last commander-in-chief of the Standing Fleet was Heihachiro Togo.
