The road markings and the specific style of the bicycle lane indicators are characteristic of Japan. The red "no smoking" sign on the sidewalk explicitly mentions "Chiyoda-ku," which is a special ward in central Tokyo. The modern architecture and the pedestrian bridge structure further confirm a dense urban environment in Japan. I am very confident this is in Tokyo.

Country: Japan
City: Tokyo (Chiyoda Ward)
Confidence: 95%
