On the 30th, the government continues to issue a "power supply and demand tight warning" within the jurisdiction of TEPCO, saying that the power supply and demand is severe during the time period from 3:00 pm to 6:00 pm, and is strictly wary of heat stroke, cooling, etc. We want to save as much power as possible while using it properly.
