With the rapid advancement of generative AI and the increasing sophistication of digital services, communications networks are facing growing demands for greater capacity, lower latency, and higher reliability. Against this backdrop, information and communications infrastructure leveraging radio spectrum is playing an increasingly important role as a critical social foundation supporting digital society. Furthermore, in addressing Japan’s structural challenges—including population decline, a declining birthrate and aging population, and the increasing severity of natural disasters—radio technologies have become a core enabling infrastructure supporting solutions across a wide range of fields, including disaster prevention, healthcare, transportation, and manufacturing.

ARIB will continue to undertake a wide range of activities to promote the efficient use of radio spectrum and contribute to the development of radio-related industries.

With regard to Beyond 5G/6G, the next-generation mobile communication systems, the Advanced Wireless Communications Study Committee will continue to study IMT-2030 radio interface technologies, while the XG Mobile Promotion Forum (XGMF) will promote not only the industrial utilization of 5G but also research and development toward 6G.

In the field of wireless LAN, ARIB will contribute to IEEE international standardization activities and to technical studies supporting the evolution of wireless LAN systems.

In the field of Intelligent Transport Systems (ITS), the ITS Information and Communications Systems Promotion Council will advance studies aimed at the development and deployment of technologies essential for automated driving, while also promoting the updating of guidelines, the development of standards, and international collaboration.

In the broadcasting field, ARIB will contribute to the development of standards supporting advanced broadcasting services, including terrestrial 4K broadcasting, as well as to international standardization activities related to technologies such as object-based audio.

In addition, we will steadily advance a broad range of activities, including consulting services such as dynamic spectrum sharing operations, public outreach initiatives through seminars and the publication of yearbooks and journals, and cooperation and collaboration with other standardization organizations.

Going forward, we will continue to work closely with our members and with relevant organizations in Japan and abroad to further the development of the radio industry. We look forward to your continued support and cooperation.
