Tokyo Gas, the Japanese LNG importer and city-gas operator, said 20,000 of its employees joined with other companies in downtown Tokyo to take part a successful day-long training drill assuming a large-scale future earthquake in the Tokyo metropolitan area.

“We carried out a comprehensive disaster prevention drill and such comprehensive drills have been conducted since 1983 with the aim of strengthening the disaster response capabilities of the Tokyo Gas Group,” said the company.

“In addition to about 20,000 employees of the Tokyo Gas Group, there was also cooperation with other Tokyo bodies, including the Metropolitan Police Department, the Metropolitan Expressway Company and Nippon Telegraph and Telephone (NTT) East Corp,” explained Tokyo Gas.

The statement said that close cooperation also ensued between Tokyo Gas and Tokyo Electric Power Grid Inc. and TEPCO Energy Partners and related organizations and other infrastructure companies.

The exercise was carried out imagining an earthquake with a maximum seismic intensity of 7 occurring in the southern part of the downtown area during daytime on a weekday in July and issues such as gas supply suspension had to be coped with.

Information flow

“We confirmed and verified the disaster response. During the training, we also carried out information linkage using the Tokyo Disaster Information System,” stated Tokyo Gas.

“This training focused on the ‘initial stage’ from the occurrence of the earthquake to about 24 hours after the earthquake, which enhances the resilience to disasters, and was conducted as a ‘blind type training’ without preparing scenarios in advance,” added the company.

The exercise included coping with various time scenarios and Tokyo Gas employees confirmed and verified how to be on alert for aftershocks and how to respond to continuous severe related incidents.

The company declared that the Tokyo Gas Group would continue to take measures against disasters such as earthquakes and work to realize a strong and safe energy supply for Japan.

Japan operates 37 separate LNG import terminals and Tokyo Gas imports around 13 million tonnes per annum of LNG.

An earthquake took place offshore eastern Japan on 11 March 2011 and became known as the Great East Japan Earthquake and Tsunami.

Around 20,000 people died in that disaster which also damaged the Fukushima nuclear plant and set in motion profound changes in the nation’s energy outlook.

It also led to Tokyo Electric Power Co. and Chubu Electric Power, the two largest users and importers of LNG in Japan, integrating their thermal power operations and LNG imports under joint venture company JERA Co. Inc.
