The Yamato Museum (Kure Maritime Museum) of Kure City, Hiroshima Prefecture, opened in 2005 with the goal of communicating science and technology that focuses on Kure’s history and shipbuilding. The museum collects and preserves those documents related to the Japanese Navy and Kure City that escaped being destroyed by fire or scattered and lost. As we progress in digitalizing the paper-based archives (pictures, blueprints, written documents), I would like here to introduce details about their preservation and how they are being shared over the internet.
