A large-scale data center project currently underway in Kagoshima Prefecture is making waves across the industry. 　 The proposed site is located near the Kyushu Electric Power Sendai Nuclear Power Station, a feature that promises a highly stable baseload power supply. As the sophistication of AI development and semiconductor manufacturing accelerates, securing reliable power has […]

The global digital infrastructure market is rapidly expanding, fueled by the Artificial Intelligence (AI) boom and surging demand for cloud services. The Asia-Pacific region, in particular, has seen a flurry of major Data Center (DC)-related deals, with transactions totaling over 800 billion yen completed in September 2025 alone. As major US tech giants like Amazon, […]

The explosive growth of generative AI has led to a skyrocketing demand for the computing resources necessary to develop and run AI models. Amid this surge, news that OpenAI is moving to invest in its own data centers (DCs) has captured significant attention. This move signals a change not just in AI development structure, but […]

Lines and Nippon Yusen K.K.   As global digitalization accelerates and the adoption of generative AI expands, the demand for data processing is increasing year after year. However, onshore data centers face significant challenges, including power supply […]

The Japanese government has started a nationwide call for proposals from municipalities to identify suitable locations for new data center clusters. The new system, known as “GX (Green Transformation) Strategic Zones,” aims to create hubs for data centers and other decarbonization-related industries. Designated regions are expected to receive preferential treatment, including subsidies funded by “GX […]

A major milestone is approaching for SoftBank’s ongoing development of AI infrastructure. With the international submarine cable connecting Tomakomai and Itoshima scheduled to open in 2028, the push to strengthen Japan’s digital foundation is in full swing. Following Tomakomai, plans for an AI-ready data center (DC) are also advancing in Asahikawa, creating a robust network […]

For a long time, Inzai City in Chiba Prefecture has been a prime location for data centers in the Tokyo metropolitan area. With ample land and easy access to the city center, it has attracted numerous major operators. However, in recent years, significant power supply constraints have emerged, posing a major challenge for new developments. […]

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 […]
