In March 2003, the Uraga Shipyard of Sumitomo Heavy Industries, Ltd.'s Yokosuka Plant, in Yokosuka, Kanagawa Prefecture, shut its gates after 105 years of continuous operation. A variety of schemes has been proposed to find a new use for the docks, which were founded in 1897, and the Yokosuka City Policy Commission asked its residents to submit proposals in the spirit of building a better city. The Commission's plan is decided soon. In this paper, I introduce the proposal that the shipyard facilities be preserved as they are, as a hands-on, open-air museum, and some of the efforts now under way to establish this museum.
