Komahashi (駒橋), was an auxiliary vessel operated by the Imperial Japanese Navy, serving from the 1910s through World War II.

[3] She was specifically intended for the role of supplying the Imperial Japanese Navy's Mako Guard District, located in the Pescadores between Taiwan and China.

[1] With the start of World War I, from 20 January 1914, Komahashi was based at Sasebo Naval District, and was converted into a submarine tender on 23 May 1914.

[3] On 1 April 1920 her classification was changed to that of a torpedo boat tender (水雷母艦, Suiraibokan), but her small size made her unsuitable for the task.

Although on 1 December 1924 she was classified once again as a submarine tender, her primary task for the next several years was that of a survey vessel, charting the area around the Pescadores and the China coast.

Upon re-launching, she surveyed around the Luzon Strait, the South Seas Mandate, the Kuril Islands and the Kamchatka Peninsula, collecting data on ocean currents, salinity, subsea topography and fisheries resources.

On 1 November, she was once again assigned to the Yokosuka Naval District, where she made 38 runs as a convoy escort and transport in waters around the Japanese home islands throughout 1943.
