Kure's proud naval history, seen in the JMSDF submarine museum and the battleship Yamato museum lives on today as Kure Harbor is home to an important part of the Japanese Marine Self-defense Force.  You can observe a large part of the fleet, including submarines belonging to the JMSDF submarine school, from "Alley Karasukojima", where one side of the street is bordered by old red brick ammunition warehouses and the waterfront offers views of destroyers, minesweepers and subs.  Ask a taxi driver to take you to "Alley Kurasukojima" or follow the map in the photo.
