The Takeshiki Guard District (竹敷要港部, Takeshiki Yōkōbu) was a navy base for the Imperial Japanese Navy located in the former Mitsushima town (美津島町) 34°16′4.8″N 129°18′43.5″E / 34.268000°N 129.312083°E / 34.268000; 129.312083 (now part of present-day Tsushima, Nagasaki), on Tsushima Island, during the Russo-Japanese War.
The Takeshiki Guard District was responsible for the control of the strategic Korea Strait, which divided Japan from the Asian mainland.
The Guard District maintained a small garrison force of ships and Naval Land Forces which reported directly to the Guard District commander, and hosted detachments from the various fleets of the Imperial Navy on a temporary assignment basis.
The port of Takeshiki on Tsushima island was selected on 1 April 1896 to be a forward staging area and coaling station under the command of the Sasebo Naval District.
It was closed on 30 September 1912, with most of its functions superseded by the Ryojun Guard District in the Kwantung Leased Territory.
