Ceiling collapse
At approximately 8 am on December 2, 2012, nearly 150 concrete ceiling panels inside the Tokyo-bound Sasago Tunnel collapsed, crushing three vehicles, including a van carrying six persons that caught fire. The fallen panels were 20 centimetres (7.9 in) thick and weighed 1.2 tonnes (1.2 long tons; 1.3 short tons) each. The caved-in point was 2 kilometres (1.2 mi) from the Tokyo-side exit and spanned a length of 50 to 60 metres (160 to 200 ft). Smoke could be seen billowing from the Kōshū entrance to the tunnel.
Nine people died and two were injured, making it the deadliest Japanese roadway accident in history. The tunnel was closed for a period of 27 days for repairs and removal of ceiling panels, before the south tube reopened on December 29. The north tube, where the collapse happened, reopened on February 8, 2013.
The nature of the collapse closely resembled a similar ceiling collapse in the Fort Point Channel Tunnel in Boston, Massachusetts in 2006.
