B2B2X Earnings
FY2023: 870 billion yen
In recent years, various social issues have come to the fore: rapid increase in the global population, growing severity of natural disasters, worsening of food supply and environmental problems, and in Japan, low birthrates and an aging population are leading to a rapid shrinking of the working-age population and shortage of labor. To solve these problems, significant social and economic transformations are being demanded in every society and economy, and the advancement of digital transformation utilizing ICT (Information and Communications Technology) is required in every situation.
Collaborating with companies in different industries and local governments as Your Value Partner, the NTT Group has been applying its management resources and capabilities, including human resources, research and development, and the ICT base to promote digital transformation and resolve social issues.
Additionally, we held an internal conference intended to deploy practices across the Group on February 22, 2023, and continue to promote the B2B2X initiative in the entire NTT Group.
In addition to citing the promotion of the B2B2X model as one of the pillars of its medium-term management plan, the NTT Group has established and is operating a Marketing Strategy Committee chaired by the President to expand the project while facilitating Group cooperation.
We are also deepening discussion about future deployment of the B2B2X business model at regularly held Board of Directors meetings and reporting on progress at general meetings of shareholders.
B2B2X is a business model aimed at resolving social issues by creating new value through collaboration with various partners.
This business model aims to provide our partner's customers (users) with new value by combining the industry expertise and customer platforms of our partners with the NTT Group's "data services" and "data management technology."
The model is being developed as an All NTT Group initiative in areas like (1) Advancing industry value chains (2) Providing better customer service (3) Utilization of mobile data (4) Community-based service and urban development.
With the formation of a partnership agreement between BRAIN SLEEP, which possesses knowledge in cutting-edge sleep medicine, and Nippon Telegraph and Telephone East Corporation and NTT DX Partners (collectively "NTT East Japan Group"), which possess advanced knowledge of and expertise in ICT technology, the NTT Group commenced initiatives geared towards the sleep technology business (June 1, 2022).
As interest in health management by corporations grows, presenteeism (the state of productivity falling, but not to the point of taking sick leave) is gaining attention as a metric for facilitating corporate productivity. It is said that presenteeism has a deep connection with sleep, and that high-quality sleep is a must for improving employee productivity.
The NTT East Japan Group and BRAIN SLEEP have commenced the provision of the "Sleep Deviation for Biz" service intended to visualize and improve employees' sleep condition at corporations and the "BRAIN SLEEP Coin" measurement device, rolling them out as a combined package that covers diagnoses of employee sleep quality and content for sleep improvement to enable employees to immediately work on improving their sleep. In doing so, we assist with the elimination of presenteeism through improving the quality of sleep of corporate employees.
Additionally, on September 3, 2022, the NTT East Japan Group and BRAIN SLEEP conducted the grand opening of "ZAKONE Sleep Network Hub"(https://zakone.jp), a virtual community through which various corporations jointly address the elimination of sleep-related issues by creating new businesses, developing services and planning events that contribute to the improvement of sleep. With ZAKONE, we have established a virtual community aimed at the further development of the sleep market through co-creation by corporations that seek to make new forays into that market and corporations already active in that market. This community tackles the creation of new innovation related to sleep issues, and has grown into one of Japan's largest communities with 68 members as of August 2023.
By taking advantage of technology to eliminate issues with sleep, which also constitutes a form of living infrastructure for people, the NTT East Japan Group will continue to contribute to the promotion of people's health, which forms the basis of corporate and social activities, with a view to the further development of regionalcorporations and communities.

Pharmaceutical companies and research institutions can view and download patient and subject PROs on the Service. In addition, a logbook function that allows subjects and patients to record all health-related data after the clinical trial as well will be provided as part of the Service by the end of FY2022. We will also consider new healthcare services that contribute to improving subjects' and patients' quality of life by safely and securely utilizing the data collected by the Service.
Through the Service, we will strive to achieve Smart Healthcare that uses digital technology to contribute to the development of healthcare.
Based on the theme of "natural," NTT will be exhibiting and sponsoring in various forms at the Expo 2025 Osaka, Kansai. We will participate in a wide range of fields, starting with the NTT Pavilion, where we will take on the challenge of sharing far-removed space and sensations with the use of IOWN, and also including the virtual Expo platform for the entire Expo venue, personal agents that maximize the visitor experience, and the onsite IOWN-APN. Additionally, on the pavilion site, we will also tackle the challenge of generating and storing hydrogen and utilizing it to power the pavilion as well as wheel the generated hydrogen to the Panasonic Group pavilion using a hydrogen pipeline.
A guidance service was launched in February 2022 within a DOOR virtual salon, provided by OriHime-D avatars piloted by handicapped people or others with difficulties going outside. DOOR users can interact with the OriHime-D avatar and ask them questions about piloting the avatar or acquire information they need.
New advances include an AI avatar providing reception duties for the DOOR virtual salon. The AI avatar developed by the NTT Group on the basis of NTT R&D technology uses automated responses to provide information outlining content available in the virtual salon, and also applies federated learning to non-verbal cues like audio data, facial expressions and intonations in voice, to give users an interactive experience.
In addition to devising intellectual property (IP) strategies to impart safety and security to the businesses of the NTT Group, which continue their challenge for the sake of new value creation and global stability, and to support the growth of those businesses, we will keep on adequately protecting the research and development results we obtain as IP as well as push forward with its utilization while respecting the IP of others.

The business activities of the NTT Group are sustained by products and services derived from the results of our aggressive R&D. For this reason, we believe that appropriate protection and utilization of intellectual property generated by R&D is vital for the NTT Group to achieve continuous growth, which in turn will enable us to continue contributing to our customers and society at large. We strive to protect the intellectual property of the NTT Group and promote activities that respect the intellectual property of others in every aspect of our business activities.
NTT protects the results of its R&D to maintain its competitive edge but at the same time makes its intellectual property available to a wider audience by licensing technologies that would contribute to the development of industries and businesses as well as standardized technologies that are already used in society.
Under the leadership of the NTT Intellectual Property Center, NTT has established policies for intellectual property activities involving the entire NTT Group and also provides support and coordination for the use and management of intellectual properties, aggregates the opinions within the Group on the intellectual property system and disseminates information outside the Group.
In order to prevent the infringement of domestic and overseas third party rights, NTT examines the third party rights of technologies used in our business at every step from the early stage of research and development up to the provision of the developed technologies to Group companies. NTT also strives to enhance the Group's compliance with intellectual property laws and regulations in Japan and abroad and mitigate potential business risks by sharing among the Group companies information on system amendments, and trends concerning intellectual property including disputes and court cases.
NTT Intellectual Property Center
Since its founding, NTT has promoted cutting edge technological development as a leading company in the information communication industry. For this reason, we own a vast number of patents.
NTT licenses its proprietary technologies so that they can be used broadly by all for the benefit of the telecommunications market as well as other markets. For example, as part of our initiatives for standardization, we efficiently promote the spread of technology by licensing patents on standardizations to many companies through various patent pools.
The results of R&D, which play a major role in the creation of intellectual property for NTT Group, has translated into ownership of approximately 18,000 patents around the world.
Among those patents, for the five green transformation (GX) technologies in the "GXTI (Green Transformation Technologies Inventory)" technological category created by the Japan Patent Office in June 2022 in order to establish a panoramic perspective of GX technologies, NTT can confirm that the research and development outcomes it has nurtured over time has yielded the ownership of patents in energy supply (gxA), batteries and energy storage (gxC) and energy saving, electrification and demand-supply flexibility (gxB), in that order.

As ICT companies leading the world, the NTT Group recognizes R&D as a material issue that gives Group companies their competitive edge. R&D supports the digital transformation of our customers and lifestyle transformations tailored to individuals, and the R&D department works with operating companies to develop new technologies that provide the wellspring for new value creation in a variety of domains to enhance the NTT Group's R&D, a pillar of our medium-term management strategy.
The NTT Group seeks to overcome numerous problems involving safety, disaster readiness, and the improvement of productivity through R&D and, as a result, strengthen industrial competitiveness and resolve social issues. Since ICT is applied in a variety of fields, we are forging partnerships with counterparts in wide-ranging industries as we pursue our R&D initiatives.
We established IOWN Global Forum, Inc. (hereinafter "IOWN GF"), a new industry forum based in the United States, together with Intel Corporation and Sony Corporation in January 2020. This forum has grown to boast membership by 111 organizations as of November 2022.
IOWN GF's objective is to accelerate the adoption of a new communication infrastructure that will bring together an all-photonic network infrastructure including silicon photonics, edge computing, and wireless distributed computing to meet our future data and computing requirements through the development of new technologies, frameworks, specifications, and reference designs.
The NTT Group's R&D activities focus on making the IOWN concept a reality, as well as basic research and applied research. Basic research serves as the backbone of telecommunications, such as basic and component technologies related to services and networks, while applied research is conducted by operating companies and is closely related to their respective businesses. These R&D activities are undertaken by NTT's IOWN Integrated Innovation Center, Service Innovation Laboratory Group, Information Network Laboratory Group, and Science and Core Technology Laboratory Group.
Also, we promote general producer activities, in which we formulate marketing and business plans and forge alliances so that the results of research by NTT laboratories can be transformed into Group businesses. In these general producer activities, we seek to develop business in a timely manner by combining the wide-ranging basic technologies of NTT laboratories with external technologies in collaboration with Group companies and with various other companies to create new services. In order for innovation to continually be an important driver of the NTT Group well into the future, we will aim to contribute to the realization of a sustainable society by promoting innovations for social issues. These efforts will include patent applications and the publication of scientific papers.
NTT, Intel Corporation and Sony Corporation established IOWN Global Forum, Inc. (hereinafter, "IOWN GF"), a new industry forum. IOWN Global Forum's objective is to accelerate the adoption of a new communication infrastructure that will bring together an all-photonic network infrastructure including silicon photonics, edge computing, and wireless distributed computing to meet our future data and computing requirements through the development of new technologies, frameworks, specifications, and reference designs.
To establish sustainable economic and social activities, it will become ever more important to effectively maximize the use of stratospheric and near-Earth space as an ICT infrastructure platform in a diverse array of fields such as energy, environment and climate change, disaster prevention, marine infrastructure, and security. Based on the "Space Integrated Computing Network Concept," NTT will take on the challenge of building new infrastructure, beginning with an optical wireless communication network to be constructed in space and a mobile network to be constructed in the stratosphere.
NTT and SKY Perfect JSAT Corporation established the "Space Compass" joint venture company that operates a novel integrated space computing network business with the aim of achieving a sustainable society. The new company is involved in space data center (high-capacity communication and computing infrastructure in space) and space RAN (communication infrastructure for Beyond5G/6G) business and services as the first step to developing an integrated space computing network. The joint venture will take on the challenge of building new infrastructures in space, where business led by the private sector is expected to grow in the future, and contribute to the creation of a sustainable society.
The development of digital technology has broughtabout a number of technological innovations, such as ultra-high definition images, but we believe that we must change our mindset to achieve further evolution.
With IOWN, we believe it is important to try to grasp phenomena and information as they are through a more diverse set of values and perceptions, as opposed to filtering them through human-only values. Dr. Jakob von Uexkull, a German biologist, proposed the concept of the "self-centered world" ("Umwelt" in German), which states that all living things have a species- specific perceptual system, and that each has a world based on its own species-specific perception and acts as its own subject. The IOWN concept is based on the idea that different subjects see things in different ways, and that the information being conveyed and the processing method will vary according to the values of each subject. Thus, it aims to convey and process every bit of information in accordance with the values of each subject.
While dramatically low latency, enormous bandwidth, and very small latency fluctuations are required to make these new ideas a reality, the current internet is reaching its limits in terms of both transmission and processing capacities. Furthermore, power consumption continues to increase in tandem with the enormous amount of information being processed, and the increase in CO2 emissions has become a serious global issue. NTT Group's vision of a high-capacity, low-latency, low-power-consumption infrastructure that can handle information as-is requires an end-to-end, fullstack redesign and optimization that breaks away from individually designed layers, from networking to computing. The key to this is "photoelectric merging" technology. Conventionally, optical signals and electronic signals have had their roles completely separated into "transmission" and "processing," respectively, and the task of converting the two types of signals is inefficient and consumes a lot of power. If we tightly integrate optics and electronics, we can apply optical technology to the entire system, down to the processor level, and we can rethink the architecture (structure) from a full stack perspective.
I think the optics-related expertise that NTT has accumulated over the years is a big advantage. What everyone is probably most familiar with is internet connection services using fiber optic cables, but NTT has long been researching the possibility of not only using fiber optic cables as a transmission medium, but using optics as a basis for transmission equipment and information processing. The results of these research projects are being put on a development track that brings them closer to commercialization, with the goal being practical applications. In terms of recent achievements, the core of "photoelectric merging technology" is the ability to perform optical-electrical and electrical- optical conversion at ultra-high speeds and with ultra-low power consumption. In LSI, the input/output (I/O) consumes the most electricity, and the impact of replacing this with light is quite significant. Moreover, with electricity, power consumption increases rapidly as the distance over which signals are transmitted increases, but with light, power consumption does not increase very quickly. Thus, by utilizing light through photoelectric merging technology, it is possible to achieve not only ultra-high speeds, an original characteristic of light, but also ultra-low power consumption. A typical example is the optical transistor developed by NTT in 2019, the first in the world to combine ultra- high speeds with ultra-low power consumption. A transistor is a conversion device that can output an electrical signal in its proper form by providing it with a control signal. Converting signals is called switching. Conventional light-switching devices are huge and cost several hundred billion yen, but now that optical transistors have been created, they have been reduced to the size of a piece of chewing gum. In addition, the research and development of optical transistors involves not only signal processing technology, but also the creation of optical modulators. This requires know-how regarding stabilization at high accuracy so as not to disturb the spectrum of a certain wavelength, which is an analog technology that is part of a cottage industry. The fact that we are now able to connect long distances optically is largely due to utilization of our technology. To cope with the increase in data volume and power consumption, a structural evolution from electronic processing to optical transmission is essential, and the breakthrough in the technology supporting this structural evolution hinges on the higher precision, smaller size, and lower cost of optical transistors. Therein lies NTT's advantage.
IOWN will be available in a variety of domains, but here are two easy-to-understand scenarios.
First, let's consider the interior of a data center, disaggregated computing. A personal computer has a similar structure, but a server has an interface, a CPU, memory, and storage. The current trend is for the CPU to issue instructions, temporarily store information in memory, and then store the information resulting from its calculations in storage.
The CPUs used to be run by electrical signals, but by directly connecting accelerators such as GPUs and DPUs via light and linking them with different wavelengths, it is no longer necessary for each server to have its own CPUs and memory. CPUs are located in one casing and memory in another, and connecting them optically makes it possible to create a situation in which it appears as if a very large amount of CPUs and memory are installed on a single server.
Disaggregated computing
This allows for a scalable computing infrastructure with ultra-low power consumption, high-speed processing, and the ability to add as many parts as required. One potential business model in this case would involve selling optical transistors. In addition to the optical transistors themselves, products that incorporate photoelectric merging technology and optical modulators into computer motherboards and semiconductor packages are also a possibility. Essentially, we would be selling key components. Next, we will expand the scope somewhat to include all-photonics networks, which utilize optics between networks, and areas outside the data center. Optical transmission technology used in the core of relay systems that connect cities and in metro networks that extend throughout cities can be expanded to the end user's neighborhood, which would allow for flexible configuration of ultra- high-capacity optical paths, such as a "one wavelength per person" model, for each application. It would be like having a dedicated, on-demand, one-toone optical line with no video compression and almost no delay in transmission and reception. optical paths, can be used to reduce power consumption.
APNs could be used for the mobile fronthaul portion that links base stations and mobile antennas. In urban areas, the population changes depending on whether it is day or night, so traffic volumes will inevitably vary. For this reason, load balancing, which dynamically constructs optical paths, can be used to reduce power consumption. APNs can also be used as lines linking data centers. These days, it is difficult to set up large data centers that require enormous amounts of power.
In the future, small- and medium-sized data centers will be dispersed over a broad area, and it will be necessary to connect these distributed data centers using light so that they can operate at a level comparable to that of large-scale data centers. Large-scale data centers require enormous amounts of electricity, but if spread out, they can also make use of renewable energy generated close to their locations, thus enabling local production for local consumption of energy. Potential business models for cases in which APNs are provided include: acting as an infrastructure service provider, such as providing mobile fronthaul and networks between data centers; a data center business that provides distributed data centers connected by APNs; and a product business selling optical transceivers to be installed in data centers edges.
All-photonics network (APN) characteristics
IOWN is an innovative concept based on light that communicates and processes things as-is and helps to create a new smart society with low energy consumption in a sustainable manner that is not attainable with our current internet. Some use cases that are anticipated at this stage include the following.
While (1) providing interconnect solutions for data center operators and (2) providing mobile networks for mobile operators have already been introduced, (3) providing networks for events (live broadcasts, cloud-based e-sports broadcasts) is another potential use case. We have already conducted demonstration tests for cloud-based e-sports event broadcasts. Competitive games via the cloud are fought in real time, and it will be essential to exchange large amounts of 8k video data with a delay of less than 20 ms. A delay of a few milliseconds compared to a delay 10 times that amount will result in a different attack timing. It is impossible to fight within a game in an environment where the timing of attacks is off due to delay. The delay in the demonstration test was 20 ms, but we are making efforts to lower this to a few milliseconds, and we are currently developing a system that can control the delay in 1-μs increments to enable synchronization.
Virtual reproduction of real life (concerts, eSports)
We hope to conduct early demonstrations of these use cases, receive feedback from customers, and further refine the IOWN technology. Then, starting around 2020, we have been proceeding with field demonstrations to users and areas that need advanced services, such as smart cities and critical infrastructure. Around fiscal 2022, we will roll out services, though it will still be limited to specific uses and areas. After 2026, we will expand the service nationwide by connecting areas where it has already been implemented. Also, an important event coming up in the near future is the Osaka Kansai Expo 2025. We hope to convey a part of our IOWN-based worldview in an easy-to-understand manner, combining some of the IOWN technologies we have mentioned thus far with existing technologies as well. In doing so, we hope to present a new kind of value through partnerships with various companies and organizations, which will lead to these technologies subsequently being implemented throughout society.

NTT East is advancing the agricultural DX concept as part of efforts to achieve a local, sustainable recycling-oriented society.
Proving support for smart agriculture by utilizing AI, IoT, drones and other ICT is part of this initiative.
While agriculture makes up the core industry in many regions, the reality is that the majority of agricultural produce relies on imports. As an IT operator, efforts were made to see if we could address the challenges that the agricultural business faces, such as an aging population and shortage of workers. NTTe-City Labo (NTT Central Training Center) harvests "NTT-grown" tomatoes available in the market grown by NTT AgriTechnology cultivation staff in its state-of-the-art vinyl greenhouses, and supplies for municipal elementary school lunches as part of a local production and consumption model. To learn how the tomatoes they eat were cultivated, 80 students from the local elementary school visited the farm as part of a field trip, making the initiative a valuable lesson for dietary education.

DOCOMO InsightMarketing provides "mobile spatial statistics" that visualizes the movement of people. Society and the economy are closely linked to how people move around. "Mobile spatial statistics" provides a way to "visualize" the movement of people, and is an essential technology as the foundation of all efforts to support society. Providing citizens with accurate data on clusters with high concentrations of people, particularly during the COVID-19 pandemic, made a significant contribution to society.
When the state of emergency was first declared in April 2020, countless people were restricted from going outside. At the time, preventing infections required avoiding "clusters," and DOCOMO received inquiries from media outlets around the clock requesting the use of "mobile spatial statistics" for identifying areas of congestion in real-time. DOCOMO also felt the need for neutral information that was not subjected to the bias of any particular media outlet. In response to these requests, efforts were made to make "mobile spatial statistics" accessible to everybody so that information could be viewed from anywhere. Population maps shown to visualize areas of congestion as heat maps were made available for free, to much positive response.
