Reader's Guide
Yokosuka's significance stems from its role as a strategic naval base and industrial hub. The Yokosuka Naval Arsenal, established in the Bakumatsu period, became central to Japan's modernization and later produced major warships like the battleship Yamashiro and aircraft carriers Hiryū and Shōkaku. After World War II, the base was taken over by the US Navy and has since served as home port for the Seventh Fleet, supporting the Korean and Vietnam Wars. The city also hosts the Nissan Oppama plant, which assembles models like the Nissan Leaf, Cube, and Juke, and the Yokosuka Research Park, a center for telecommunications R&D.
