Katsuhiko Kawazoe, Senior Executive Vice President, NTT▼Abstract
The NTT Group is taking on the challenge of creating a Smart World that enriches
the lives of all people around the world through its efforts in a variety of fields. By
implementing the Innovative Optical and Wireless Network (IOWN), the group aims
to solve social issues and create innovative services. We interviewed Katsuhiko
Kawazoe, senior executive vice president of NTT, who coined the term “IOWN,”
about the development status of IOWN and his approach to his work as a top
executive.

This article introduces the intent AI (artificialintelligence) mediator called Mintent that coordinatesand cooperatively controls networks, cloud servers,and applications on the basis of the respective
requirements (intents) of service providers andusers. This technology can be used to provide
services on the basis of such intents.
