Abstract
Accompanying the daily evolution of information and communication technology,
artificial intelligence and other digital technologies, the rise of diverse businessmodels and the expansion of remote work fast-tracked by the COVID-19 pandemic
has changed society dramatically. Under these circumstances, birthrates aredeclining and populations are aging at higher rates, social infrastructure isdeteriorating, and countermeasures against global warming are becoming ever moreurgent. To address such social issues facing Japan, NTT EAST is promoting
empathetic digital transformation (DX) in conjunction with traditional problem solving.
We asked President Naoki Shibutani about how empathetic DX is important to drivesocial innovation as well as the secret of “management from the heart” that he ispursuing.

In Japan, the Act on Promotion of Children’s Reading was enacted in 2001. With therapid increase in the number of middle- and high-school students owning
smartphones and the launch of the government’s GIGA School program for creating
an environment in which every student has one device connected to the Internet, theimpact of reading habits during infancy on the academic performance of children is
attracting attention. We interviewed Tessei Kobayashi, a senior distinguishedresearcher at NTT Communication Science Laboratories, about the progress of his
research activities to elucidate the mechanisms of children’s language development
and using these mechanisms to support education.

There is an urgent need to ensure the sustainability of social activity. This makes it all the more important touse space for information and communication technology (ICT) infrastructures. This involves creating ICT
infrastructures that support a number of fields, including energy, environment, and disaster prevention. To
this end, NTT and SKY Perfect JSAT have established a joint venture company, Space Compass
Corporation, that will launch a novel space ICT infrastructure, the Space Integrated Computing Network.
This article gives an overview, business outline, and future prospects of this network.
