The incident started at 08:00 local time (23:00 GMT Saturday), about 80km (50 miles) west of Tokyo on a road that links it to the city of Nagoya.
Survivors described how large sections of concrete fell on top of cars in the Sasago tunnel.
Pictures from closed circuit TV cameras inside the tunnel showed a section of up to 100m (328ft) that had caved in on the Tokyo-bound lanes on the Chuo Expressway in Yamanashi prefecture.
A fire broke out and rescuers said a number of charred bodies had been seen.
