the Shinji Pond and the First Flower Garden, which are located in the northeast area of Hibiya Park. We
also found a high accumulation of photo-taking locations at the Kumogata Pond, Matsumotorou
restaurant, and the Second Flower Garden. When density distribution on the small scale is calculated and
visualized, it is not clear whether the photo-taking locations are distributed in the surrounding of these
attractions. The density was lower at the Kusachi Hiroba, the west side of the tennis court and the
surrounding of the Hibiya Library and Hibiya Hall. The reason for this is that most participants did not
visit that place; this became clear by checking their GPS logs.
