Police said 26-year-old Sakamoto was driving his car on the rooftop parking space in Fukuoka's busy Tenjin district at about 10 a.m. when, for some unknown reason, the car broke through the rooftop's barrier at high speed.
The car flew over an eight-meter wide street and landed upside down on top of a two-story building on the other side.
