Naoki Shibutani, Senior Executive Vice President, NTT▼Overview
To solve social problems, it is important to promote digital transformation using
information and communication technology. The efforts of the NTT Group to solve
such problems have been highly evaluated both in Japan and overseas, e.g., being
selected as a “Derwent Top 100 Global Innovator” for nine consecutive years. We
asked Naoki Shibutani, a senior executive vice president of NTT, about his current
duties and the required attitude of the senior management regarding the ability of theiremployees to solving social problems in the world that has changed significantly due
to the novel coronavirus pandemic.
