The Mako Guard District (馬公警備府, Makō Keibifu) was the major navy base for the Imperial Japanese Navy in Taiwan before and during World War II. Located in Mako 23°35′24″N 119°34′05″E / 23.590°N 119.568°E, (present-day Makung, Pescadores Islands, Republic of China), the Mako Guard District was responsible for control of the strategic Straits of Taiwan and for patrols along the Taiwan and China coastlines and in the South China Sea. It was disbanded in 1943, and reestablished as the Takao Guard District at Takao on the Taiwan main island.
