This museum is located inside a ship with a long history, as it was one of the ships that Korea sent to spy on Japan in the last century, and at that time the Coast Guard was able to identify the ship and arrest the spies. The ship has been converted into a museum to glorify the heroic coast guard and their ancient history in protecting Japan and the city, because Japan is an island country and has a large number of coast guards. Among the exhibits in the museum there are weapons and costumes, some old photographs and drawings, and much more.
