Tokyo Night & Light is a free light show that projects video onto the exterior walls of the Tokyo Metropolitan Government Building plaza in Tokyo. It can be viewed together with the Tokyo Metropolitan Government Building observation deck, with a different video shown each month and a cycle of 20 minutes of playback followed by a 10-minute break. The south observation deck operates until 22:00, but hours vary by date, so the timetable on the official website needs to be checked. The building is tall and the lawn is close, so looking up at it strains the neck.
