Sendai, Japan—A multi-vehicle pileup on the Tohoku Expressway left two people dead Wednesday morning. The crash occurred in a northbound lane as traffic slowed significantly due to heavy regional congestion.

Emergency responders reached the site within minutes of the collision. They found several passenger vehicles crushed between two large freight trucks.

Police closed the expressway in both directions to allow medical helicopters and rescue units access to the wreckage. Traffic backed up for several kilometers as authorities cleared the path for heavy equipment.

Paramedics confirmed two deaths at the scene. Three other individuals involved in the pileup suffered moderate to severe injuries and required immediate transport to local hospitals.

Preliminary investigations suggest the lead vehicle braked suddenly, causing a chain reaction of rear-end impacts. The slick road conditions from earlier morning mist likely played a role in the severity of the crash.

Traffic control officers worked through the afternoon to move the damaged vehicles off the main thoroughfare. Commuters faced massive delays as rerouting measures remained in place throughout the day.

Authorities are currently reviewing dashcam footage from surrounding vehicles to determine the precise sequence of events. The names of the deceased are being withheld until family notification is finalized.

The expressway reopened partially in the late afternoon. Police continue to monitor the scene for debris and structural road damage.
