The Future of Memory: Japanese Professor Uses 3D Technology to Redefine How We Experience History
On a laptop screen in a quiet lab at the University of Tokyo, the city of Hiroshima unfolds in unnerving detail. Streets, houses, rivers ā all reconstructed as they stood on a bright summer morning in 1945. Then, with a few clicks, the map reveals what came after: devastation stretching in every direction. Itās not a movie clip or a static photo. Itās a way to zoom, pan, and step through the city. This is history revealed as a living, explorable world. This is the work of Hidenori Watanave, a professor and information design specialist who has spent two decades transforming how we engage with memory. His projects include interactive archives of the people who survived the Hiroshima and Nagasaki bombings, real-time maps of the war in Ukraine, and a full 3D model of a Japanese Navy Type Zero Reconnaissance Seaplane pulled from the sea. All of his projects share a single mission: to connect people across time and space, to events they might otherwise only encounter in textbooks or headlines. And increasingly, those worlds are powered by Cesium, the open-source 3D geospatial platform that can stream vast datasets into a browser while rendering fine detail at every scale ā
