1 Derailed vehicle status and restoration work status
　Of the five derails, three cars (cars 2, 3, and 6) were lifted up on the rail.
　On the other hand, in Cars 4 and 5 in the middle, the wheels sink into the ballast (crushed stone laid under the makuragi) due to severe damage to the makuragi, so the body is inclined and approach the tunnel side wall.
　In addition, it was found that the trolley of Car 6 on the rail was distorted, and other vehicles may not be able to withstand transport to the depot, so we are reviewing the removal method.
　During this period, in addition to the officials of JR East, Tokyu Corporation, and contractors have been very helpful in carrying out the work during this period, and a total of 650 workers are engaged in the work.

　In addition, we will provide information on the restoration status and the prospect of resuming all lines at any time.

3 Future restoration work and necessary processes
　Regarding the removal of derailed vehicles to the rails and removal of vehicles, we will consider all possible methods while giving maximum consideration to safety to prevent secondary disaster from occurring.

4 Future Operations
　The Blue Line will be operated back all day between Azamino and the landing.
