An environmental image-building technique in walking tours enables citizens to improve local environmental perception. We have designed and carried out serial events in “UEMACHI-HILL PROJECT” as an effective method of developing semantic cognition of environment. In the project, “Tagging intimately environmental resources in urban spaces” is examined as one of the techniques to aid of their image-building.
Participants in the event would give local environmental resources nicknames accompanied by following two effects. One is to make participants feel much more attached to the local environmental resources, the other is to build diversified environmental image. Findings are as follows: 1) “Tagging” can support participants to develop environmental image in the context of mental linkage to physical properties; 2) Participants would improve local environmental image using “Tagging” technique in their daily lives;and 3) It is important that participants share their images with each other in the “Tagging” process.
