NTT’s push to implement IOWN (Innovative Optical and Wireless Network), its next-generation infrastructure concept, is gaining momentum. In June 2025, NTT announced the successful completion of a proof-of-concept for the All-Photonics Network (APN), a core component of the IOWN vision. This new optical network technology can achieve communication that surpasses the limits of the existing […]

In recent years, “decentralization” has garnered significant attention within the data center (DC) industry. The Japanese government and Tokyo Electric Power Company are promoting initiatives like “Watt-Bit collaboration,” which links power and data communication, to encourage the shift of data centers away from urban concentrations. The underlying objectives include mitigating earthquake and disaster risks and […]

The Japanese government is now clearly emphasizing the importance of “Watt-Bit Collaboration”—the fusion of energy and digital technologies. The 2024 Basic Policy on Economic and Fiscal Management and Reform has positioned this collaboration as a core strategy, aiming to create a framework that simultaneously solves regional challenges and drives economic growth by integrally utilizing watts […]

Tokyo Electric Power Company Power Grid (TEPCO PG) has established TEPCO Digital Infrastructure Co., Ltd. to advance its digital infrastructure business. This move comes against a backdrop of an explosion in data demand and the redefinition of power infrastructure driven by the widespread adoption of advanced digital technologies like generative AI. Power companies are no […]

The trend towards increasingly large-scale data centers (DCs) is gaining serious traction, highlighted by Tsukuba’s first hyperscale data center project, which drew significant attention during its bidding phase.
