The National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki Ph.D.), in collaboration with Sony Semiconductor Solutions Corporation (Sony), has developed the world's first practical surface-emitting laser that employs quantum dot(QD) as the optical gain medium for use in optical fiber communication systems.

A joint research team from Nagoya University Institute for Space-Earth Environmental Research, the University of Oslo Faculty of Mathematics and Natural Sciences, Kyoto University Institute for Integrated Cell-Material Sciences, and the National Institute of Information and Communications Technology conducted ionospheric tomography analysis using data from Japan's ultra-dense GNSS observation network. They clarified, for the first time, the 3D characteristics of ionospheric electron density fluctuations, spatially and temporally evolving, immediately following the Noto Peninsula Earthquake of 2024.

An international research team led by the Photonic Network Laboratory at the National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki Ph.D.), and including Sumitomo Electric Industries, Ltd. (Sumitomo Electric, President: INOUE Osamu) have set a new world record in optical fiber communications, achieving data transmission at 1.02 petabits per second over a distance of 1,808 kilometers (roughly equivalent to the distance from Sapporo to Fukuoka, from Missouri to Montana or from Berlin to Naples).

A research group led by Prof. Yoshinao Kumagai of Tokyo University of Agriculture and Technology, in collaboration with Mr. Junya Yoshinaga of TAIYO NIPPON SANSO CORPORATION, Assistant Prof. Shogo Sasaki of Nara Women’s University, Prof. Takeyoshi Onuma of Kogakuin University, Prof. Masataka Higashiwaki of Osaka Metropolitan University / National Institute of Information and Communications Technology, and Dr. Yuzaburo Ban of TAIYO NIPPON SANSO ATI CORPORATION, has successfully developed a technique for precise control of n-type conductivity in high-speed growth of β-Ga₂O₃ homoepitaxial layers using their proprietary low-pressure hot-wall MOVPE method.

A research group led by FUJINO Misako and HARUNO Masahiko at the National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki Ph.D.), has demonstrated that experiencing active flight in VR allows individuals to predict that they can transition to a safe state even if they fall from a height, thereby reducing fear responses. This discovery challenges the traditional understanding that fear extinction necessarily requires repeated exposure to fear-inducing stimuli.

A research team led by Dr. TANAKA Toshiko and Dr. HARUNO Masahiko at the National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki Ph.D.), investigated how avatar-mediated communication affects human decision-making. They discovered that participants were more likely to take risks when facial expressions (such as admiration or contempt) were displayed by avatars than when the same expressions were shown on real human faces. This increase in risk-taking was found to result from a more favorable valuation of the "uncertainty" of facial feedback in the avatar condition.

Tokyo, 31.3.2025 - In a bold step toward revolutionizing network technologies, the National Institute of Information and Communications Technology (NICT) and the Fraunhofer Heinrich-Hertz-Institut (HHI) in Germany launch the Optical Testbed Dataspace (OTDS). OTDS is a pioneering platform designed to accelerate the development and testing of Artificial Intelligence (AI) and Machine Learning (ML) models for optical networks. It fosters global collaboration by enabling international partners to securely share and aggregate testbed data from diverse environments, pushing the boundaries of network optimization and automation.

The National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki, Ph.D.) has revealed, through fMRI-based brain activity analysis, that multiple regions in the human cerebral cortex flexibly represent numerical quantity. This finding comes from research by HAYASHI Masamichi (Researcher (Tenure-Track)) at Center for Information and Neural Networks (CiNet), part of NICT’s Advanced ICT Research Institute, in collaboration with the University of Tokyo’s graduate student KIDO Teruaki (NICT cooperative visiting researcher), and Prof. YOTSUMOTO Yuko.

The Japan Aerospace Exploration Agency (JAXA, President: Hiroshi Yamakawa) and the National Institute of Information and Communications Technology (NICT, President: Hideyuki Tokuda) have successfully completed the commissioning and the initial calibration & validation　 for the Cloud Profiling Radar (CPR), which was jointly developed by JAXA and NICT, onboard Earth Cloud Aerosol and Radiation Explorer (EarthCARE) (Nickname: “Hakuryu”).

As neuroscience progresses, ethical, legal, and sociological issues (ELSI) in neuroscience are not only expanding, but also becoming more complex. This conference will be an in-person international meeting with participants from not only the field of neuroscience, but also internationally recognized leaders and promising young researchers from fields related to ELSI in neuroscience, such as ethics, law, and sociology.

The National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki, Ph.D.), NTT Corporation (NTT, President: Mr. SHIMADA Akira), Tohoku University (President: Dr. TOMINAGA Teiji) and the Tokai National Higher Education and Research System Nagoya University (President: Dr. SUGIYAMA Naoshi) succeeded in developing a new type of superconducting flux qubit that operates in zero magnetic field.

Tokyo - October 7, 2024 - TOPPAN Digital Inc. (TOPPAN Digital), a TOPPAN Group company and wholly owned subsidiary of TOPPAN Holdings Inc. (TYO: 7911), the National Institute of Information and Communications Technology (NICT), and ISARA Corporation (ISARA) have developed SecureBridge™, a smart card system capable of supporting both currently used public-key cryptography and post-quantum cryptography (PQC) that is secure against attacks from quantum computers.

An international research team led by the Photonic Network Laboratory of the National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki, Ph.D.) demonstrated a coherent optical fiber communication system with a total transmission capacity of 336 Tb/s. The system uses a single light source combined with optical comb generation and frequency reference distribution, eliminating the need for hundreds of built-in light sources within transponder modules.

TOKYO—September 3, 2024—NTT Corporation (Headquarters: Chiyoda Ward, Tokyo; Representative Member of the Board and President: SHIMADA Akira; hereinafter "NTT") and Cybersecurity Laboratory of the National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki, Ph.D.) conducted a systematic review of papers published as user studies (studies involving participants) in the security and privacy field. The review quantitatively revealed that many existing studies focus on populations from limited geographical and cultural regions, primarily in the West.
