Timed to correspond with “Disaster Preparedness Day”, on September 1st, 2017 a comprehensive disaster drill was held on the premise of an earthquake that directly hit the central Tokyo area.
In addition to disaster recovery support such as ascertaining the extent of damage caused of the earthquake and requesting urgent supply of fuel in an assumed wide-ranging power outage, responses to a cyberattack carried out under the cover of the disaster were practiced.
On December 13, 2017, we participated in the traversal cross-section training exercises held by the National Center of Incident Readiness and Strategy for Cybersecurity (NISC).
On the premise that the cyberattack impacted vital infrastructure such as communications, NTT Group companies conducted training in cooperative measures with companies in other industries.
In May, 2017, the combined NTT group companies held disaster training drills using NTT World Engineering Marine Corporation’s subsea cable-laying vessel “Kizuna”.
On the premise of transporting emergency vehicles and communications equipment to a disaster-stricken region, we trained in loading and other activities.
Timed to correspond with “Disaster Preparedness Day”, on September 1st, 2016 a comprehensive disaster drill was held on the premise of a Nankai Trough earthquake.
The exercise assumed a case where extensive damage had been done by a tsunami resulting from a Nankai Trough earthquake and telephone land lines were temporarily unusable. Using a wide variety of communication means such as satellite communications, members of the countermeasures task force who participated in the training exercise were able to fully comprehend the extent of the damage and practiced how to support restoration efforts in a precise and timely manner.
In the Nankai Trough seismic countermeasures, cross-departmental review meeting that was held after completion of the drill, actions that should be taken immediately after a disaster occurs were identified and in addition to reconfirmation of cooperation links and details, a range of opinions were exchanged about actions to be taken in ordinary times. The exercise and review will lead to a strengthening of task force member’s response capabilities through solutions to the various issues.
Usually, when carrying out drills in concert with the Japanese government's September 1 (National Disaster Prevention Day) comprehensive disaster prevention drill program, we do so at our headquarters. In Fiscal 2015, however, anticipating the possibility that it might become difficult for members of the NTT Disaster Countermeasures Office to reach the city center in the event of a strong earthquake occurring below Tokyo, we instead established an alternate countermeasure office on the outskirts of the city and carried out drills at this location.
At the alternate location, NTT Disaster Countermeasures Office members set out on foot and bicycle to implement a range of drills and inspections that would be vital during a disaster.
The exercises examined important issues in ensuring that the NTT Disaster Countermeasures Office remains functional under any and all conditions. In the future we will continue to develop drills geared toward a diverse array of situations, striving for a smooth, rapid response in times of crisis and more complete disaster countermeasures throughout the NTT Group.
Acting in concert with the government's annual comprehensive disaster drills held on September 1, Japan's Disaster Prevention Day, NTT Corporation conducted a series of comprehensive disaster drills and exercises to verify the operational readiness of the NTT Disaster Countermeasures Office in the event of an earthquake hitting the Tokyo metropolitan area.
Continuing from fiscal 2013, we conducted the drill scenarios without informing participants beyond the members of the Holding Company Disaster Countermeasures Office. This year, we enacted a scenario that assumed wide-area and lengthy power failures, in order to check operations such as workflows related to the procurement of fuel required for emergency power sources.
By continuing to implement drills that envision a variety of scenarios, we will work to build up operational know-how within the NTT Disaster Countermeasures Office and, at the same time, check and verify the Office's operational structure with a focus on response by the NTT Group as a whole as we strive to enable smooth, prompt, and appropriate execution of response to emergencies.
Acting in concert with the comprehensive disaster drills held by the government, we conducted drills for the operation of the NTT Disaster Countermeasures Office.
Participants were initially told only that the drill would focus on an earthquake occurring on September 1 in the Nankai Trough south of Japan. In the ensuing scenario, members of the Holding Company Disaster Countermeasures Office unveiled situations based on activities following the Great East Japan Earthquake. Conducting drills in this manner allowed us to train under realistic conditions and check the actions of whole NTT Group in a more tension-filled atmosphere.
In January 2014, the NTT Group participated in the government's annual comprehensive disaster simulation exercises that envisioned an earthquake in the Tokyo metropolitan area. Based on guidelines including the government's Guidelines for Emergency Response Activities, we implemented simulation exercises in a roleplaying format to improve the ability of the Disaster Countermeasures Office to execute disaster response-related work. We also checked our sharing of information with the nine participating prefectures and cities of the Greater Tokyo area and other designated public institutions, including railways and electric power utilities.
In addition, in March 2014 we conducted hands-on drills envisioning an earthquake hitting the Tokyo metropolitan area, in order to further enhance cooperation and disaster response capabilities of the NTT Group and the Japan Ground Self-Defense Force Eastern Army Headquarters.
Coinciding with the government's comprehensive disaster drills envisioning an earthquake hitting the Tokyo metropolitan area, we conducted drills involving operation of the NTT Disaster Countermeasures Office and the setup of an alternate site in the event of damage to the site normally planned.
With participation by all members of the Office, we performed checks of basic procedures related to emergency call-up and the setup and operation of the Office site following an earthquake, as well as checks of our system for sharing information in cooperation with group companies.
NTT Corporation and group companies also took part in the annual comprehensive disaster simulation exercises hosted by the government. These exercises are held to verify the efficacy of emergency response measures and to improve the ability to execute the work of the Disaster Countermeasures Office, along with work involving cooperation with relevant regional authorities, designated public institutions, and other organizations, based on guidelines including the government's Guidelines for Emergency Response Activities.
The exercises were held in the Chiyoda Ward of Tokyo in January 2013 with the participation of the central government, regional authorities, designated public institutions, and volunteers. From the NTT Group, NTT Corporation (holding company), NTT East Corporation, and NTT DOCOMO took part in the drills, with a focus on checking operations.
