History
Inauguration of the Japan Coast Guard on May 1. 1948
At this time, Japan was under occupation immediately after WWII. Operations were limited at the onset for the Japan Coast Guard with limitations on the number of crew members, officers, and ships, and also such as ship speed. Such limitations resulting from the United Nations, although not a military entity, being careful in the organization of a units with maritime capabilities.

On May 12, 1948, the official flag of JCG was hoisted for the first time by Takeo Okubo, the first Commandant of the JCG on the roof of the JCG Headquarters.
