NTT East, NTT docomo, KDDI, Tokyo Gas, and Tokyo Electric Power conducted joint field training in Saitama Prefecture on June 4th. This was the second time the five companies have conducted joint training together. It was the first time in Saitama Prefecture.

Tokyo Electric Power Saitama Branch Manager Jun Sugimoto said, “We believe that joint field training is a very important and valuable time for infrastructure companies to gather together, build face-to-face relationships, strengthen relationships, and prepare for disasters.”

The training was based on the assumption that a fierce typhoon had passed through the Kanto region in early August, causing severe damage in Saitama Prefecture, including the collapse of houses due to the storm and the disruption of lifelines. The infrastructure companies worked together to quickly restore lifelines.

NTT East and Tokyo Electric Power conducted a joint road clearance training. NTT East carried out the work of removing TEPCO’s power poles on behalf of TEPCO.
In the event of a large-scale disaster, TEPCO employees may not be able to arrive at the scene promptly. Saitama Prefecture can remove the poles on behalf of TEPCO, but even in such cases, TEPCO employees must always check for safety.
In the training, TEPCO engineers removed the high-voltage lines and handed the work over to NTT East engineers. NTT East engineers moved the poles to the side of the road with a crane. The poles on the side of the road were surrounded by safety cones to prevent third parties from approaching.

In addition, NTT docomo and KDDI set up mobile base station vehicles and support equipment at evacuation centers as part of emergency restoration of mobile services.
The mobile base station vehicles are equipped with wireless equipment and an automatic generator. The transmission line connects to the satellite line via an antenna installed on the roof, so area relief can be achieved using only the vehicles.
