 Toru Takama, President & CEO, NTT Anode Energy Corporation
Overview
NTT Anode Energy is promoting the smart energy solution business, which leverages the resources and information and communication technologies possessed by the NTT Group. Two years after its establishment, the company is striving to contribute to resolving social issues, such as environmental and population problems, revitalizing industry, and building a sustainable society. We interviewed Toru Takama, president and chief executive officer of NTT Anode Energy, about the progress of business to promote and expand renewable energy and the mindset of top management.
Front-line Researchers
- Yasushi Takatori, Senior Distinguished Researcher, NTT Access Network Service Systems Laboratories
Overview
Future networks are expected to provide high-speed, large-capacity communications and enormous amount of computing resources that exceed the limits of the conventional network infrastructure. To meet these expectations, NTT is conducting research and development on the Innovative Optical and Wireless Network (IOWN), a future information-processing infrastructure that includes user’s terminals. Yasushi Takatori, a senior distinguished researcher at NTT Access Network Service Systems Laboratories, is taking on the challenge of innovating wireless access toward the 6G (six-generation mobile communication system) era, which will be an essential component of IOWN. We asked him about his research activities and his attitude as a researcher.
Rising Researchers
- Atsutoshi Kumagai, Distinguished Researcher, NTT Computer and Data Science Laboratories and NTT Social Informatics Laboratories
Overview
Machine learning is needed to build artificial intelligence (AI), and this requires a large amount of training data. Sometimes, however, you cannot get enough high-quality training data. What’s more, to prevent an AI from becoming out of date, you need to re-train it regularly to keep pace with data that is constantly changing. In this interview, Distinguished Researcher Atsutoshi Kumagai talked to us about the technology of transfer learning, which can be used to improve AI performance even when ideal data cannot be obtained.

 Research and Development of Digital Twin Computing for Creating a Digitalized World
Abstract
The Digital Twin Computing Research Project aims to make Digital Twin Computing, a key component of the Innovative Optical and Wireless Network (IOWN) initiative promoted by NTT, a reality. We established four grand challenges to achieve this objective and have been conducting research and development to meet each one. This article outlines each grand challenge and associated technologies and describes horizontal activities across these challenges.
- Thought-processing Technology for Understanding, Reproducing, and Extending Human Thinking Ability
Abstract
The Human Insight Laboratory at NTT Human Informatics Laboratories aims to deepen our understanding of human thinking ability, which consists of human information understanding, human information processing, and response and behavior, and to create technologies that can reproduce these abilities on computers and expand human thinking ability. In this article, the technologies of visual machine reading comprehension, behavior modeling, speech recognition, and thought-enhancing stimulus design are introduced.
- Research on Symbiotic Intelligence for Achieving Symbiosis among People and between People and Machines
Abstract
With the rapidly progressing fusion of the real and cyber worlds, the manner of symbiosis among people and between people and machines is changing significantly. Information and communication technologies will make it possible to gently guide the behavior of people and groups toward a better future and shared emotions and to enable people and machines to work together through more-natural and complex interactions. An overview of the research being conducted by the Symbiotic Intelligence Research Project toward this future vision is given in this article.
- Cybernetics Technologies for Symbiosis between People and Machines
Abstract
With the development of computing technology and artificial intelligence, an environment in which we can use advanced information and communication services in our daily lives is rapidly being established. By installing mechanisms that recognize and understand in a more human-oriented manner than conventional technologies, we aim to create a society in which people and machines can coexist in harmony. In this article, we introduce our research themes for achieving this aim.
- Elemental Technologies for Supporting the Integration of Real Space and Cyberspace
Abstract
To create a human-centered society in which everyone can lead a comfortable, vibrant, and high-quality life, we hope that a system that integrates real space and cyberspace will become a reality. In this article, a mobile mapping system (MMS) point cloud data processing technology called geoNebulaTM is introduced, which analyzes data measured in real space, recognizes space and objects, and compresses the data into a compact form suitable for constructing cyberspace. This technology is being researched and developed to establish a mechanism for creating value through the sophisticated blending of real space and cyberspace.
Feature Articles: Olympic and Paralympic Games Tokyo 2020 and NTT R&D—Technologies for Viewing Tokyo 2020 Games
- Introduction
- Initiatives for a New Sports-viewing Experience
- Sailing × Ultra-realistic Communication Technology Kirari!
Abstract
NTT provided its ultra-realistic communication technology called Kirari! to the TOKYO 2020 5G PROJECT, which was implemented by the Tokyo Organising Committee of the Olympic and Paralympic Games to offer a new experience of sports viewing by using 5G (5th-generation mobile communication system). A new experience of watching sports at the sailing regatta, held at the Enoshima Yacht Harbor, is introduced in this article. In short, a sense of realism—as if the spectators were watching the races from close up—was provided by transmitting ultra-wide video images taken close to the race course to the spectators’ seats set up at the harbor.
- Badminton × Ultra-realistic Communication Technology Kirari!
Abstract
NTT provided technical support through Kirari!, an ultra-realistic communication technology, for the TOKYO 2020 Future Sports Viewing Project spearheaded by the Tokyo Organising Committee of the Olympic and Paralympic Games. This article presents results of demonstrations of a next-generation immersive technology for providing a sense of “being there,” namely through the sense of presence and sense of unity, by transmitting holographic images of the badminton matches held at Musashino Forest Sport Plaza to a remote location (National Museum of Emerging Science and Innovation (Miraikan)).
- Marathon × Ultra-low-latency Communication Technology
Abstract
NTT provided ultra-low-latency communication technology to the Tokyo 2020 Real-time Remote-cheering Project, which was implemented by the Tokyo Organising Committee of the Olympic and Paralympic Games for the marathons of the Olympic and Paralympic Games Tokyo 2020 held in Sapporo on August 7 and 8, 2021. This project proposed a new means of watching sports by connecting the marathon course in Sapporo with the cheering venue in Tokyo in real time. By delivering the cheers of spectators to the athletes from the remote location in Tokyo, it was possible to create a sense of unity between the athletes and spectators, as well as a sense of realism similar to roadside cheering while maintaining safety and security. Our efforts concerning this project and the technologies that we used are introduced in this article.
Global Standardization Activities
- High-accuracy Time-synchronization Technology for Low-latency, High-capacity Communications in the 5G and Beyond 5G eras
Abstract
High-accuracy time-synchronization technology has been attracting attention for enabling services that use high-accuracy time information, such as fifth-generation (5G) mobile communications, high-frequency financial transactions, high-definition video distribution, and smart grids. The International Telecommunication Union - Telecommunication Standardization Sector (ITU-T) Study Group (SG) 15 and the Institute of Electrical and Electronics Engineers (IEEE) mainly carry out international standardization. In this article, we introduce the time-synchronization requirements for 5G as well as next-generation communication technologies, such as Beyond 5G and quantum communications, an overview of time-synchronization technology/Precision Time Protocol (PTP), the standards of which have recently been updated by IEEE, and the latest discussion topics in ITU-T SG15.
