The blue bridge which Ishigami crossed in the film “Suspect X"

The blue bridge that Tetsuya Ishigami (played by Shinichi Tsutsumi) crosses on his way to work in the film "Suspect X" (2008) is the “Kiyosu Bridge” over the Sumida River. The bridge was built by utilizing cutting edge technology of the time as a symbol of the Reconstruction Project of the Imperial Capital following the Great Kanto Earthquake, and is designated as a national important cultural asset, along with the Eitai Bridge and the Kachidoki Bridge. The suspension bridge designed in feminine and graceful form is illuminated in pink light in the evening.
