Examining an old photograph at the exact location where it was captured helps understanding the photograph deeply. We developed an AR application for mobile devices designed to provide a virtual experience of past scenery by superimposing old photographs on current landscapes. We introduced the application to a walking guided tour. Designing a route of walking guided tour and authoring AR contents shown on the tour was done collaboratively with us and tour guides. The tour titled ” Travel around Fukagawa at the time of last olympic, 1964” took place in Koto city, Tokyo with 12 participants. The tour was planned for 1.5 hour tour and it had 13 old photographs. This paper describes implementation of the application, design process of a walking guided tour, and feedback of the tour from both participants and guides.
