The green road sign uses Japanese script and mentions "Honcho," which is a common district name in Japan. The driving is on the left side of the road, which is standard in Japan.

The architecture and the specific style of the road signs confirm this is definitely Japan. I suspect this is in the Chuo or Nihonbashi area of Tokyo.
