Executive Manager of Digital Transformation Headquarters,
NTT EAST▼Overview
In today’s society, in which technological innovation and market changes areaccelerating, NTT EAST is committed to solving problems of local communities
while valuing the ties that it has cultivated with those communities over the morethan 100 years in the telephone business. We interviewed Hiroshi Tanabe, senior
executive vice president of NTT EAST, about his thought on the use of technology
to solve social problems and why he has been focusing on helping front-line
employees shine.

Masaaki Nagata, Senior Distinguished Researcher, NTTCommunication Science Laboratories
Research on machine translation using neural networks has made rapid progress,
and the accuracy of machine translation has improved considerably. Althoughwebsites and smartphone apps providing machine translation have become more
popular, issues with accuracy remain. We interviewed Masaaki Nagata, seniordistinguished researcher at NTT Communication Science Laboratories, who isresearching context- and situation-based neural machine translation, about theprogress of his research and what it means to be a researcher.

Research and Development on Technologies for Transforming
the Global Environment from a Space Perspective▼Abstract
NTT Space Environment and Energy Laboratories was established in July 2020 to develop innovativetechnologies for regenerating the global environment and achieving a sustainable and inclusive society. We
are the first NTT laboratories with “space” in our name, but our purpose is not to conduct research on space
itself. Rather, we study the Earth from the perspective of the space environment, including the Sun, andtake on challenging studies with the aim of transforming the future of the global environment from dynamic
viewpoints.
