The Ni-Tele Really Big Clock (日テレ大時計, Nittere Ōdokei) is a large clock and sculpture designed by Hayao Miyazaki, installed outside the second story of the Nittele Tower in Minato Ward, Tokyo, Japan.

The structure, which is made entirely of hand-worked copper and steel plates, is 12 meters tall by 18 meters long and contains 32 separate moving mechanical features.

This clockwork assembly performs a three-minute show a few times each day (four on weekdays, five on weekends).
