AI Storm's Strategic Initiative in Nagano Prefecture

On May 20, 2026, AI Storm Co., Ltd., formerly known as Jexceed, headquartered in Chiyoda-ku, Tokyo, initiated a significant step towards enhancing its operational capabilities in the AI sector. The establishment of a special purpose company, AICore Grid LLC, and a data center operational entity, AIS DC Services Co., Ltd., marks the beginning of AI Storm's AI data center venture in Nagano Prefecture. This dual-company approach will enable focused asset management and operational efficiency in the growing AI infrastructure realm.

Background Perspective

In April 2025, AI Storm officially rebranded itself. Along with the rebranding, the company unveiled a mid-term management plan aiming at achieving a market capitalization of 50 billion yen within three years. The renewed commitment to AI services forms a crucial part of this vision, evident through the developments in Nagano.

The decision to establish these companies responds to the soaring demand for AI infrastructure and the current geographical disparities in Japan’s data center markets. While the domestic co-location market is projected to grow to a staggering 1.78 trillion yen by 2029, with an annual growth rate estimated at 12.9% (according to IDC Japan), over 80% of the existing data centers are concentrated in the Tokyo and Osaka regions. This imbalance presents an essential opportunity for growth, making the establishment of strategic sites in lesser-tapped areas a national priority.

The Geographic Advantage of Nagano

AI Storm recognizes the challenge and is proactively addressing the regional disparities by repurposing an old factory site in Nagano for its AI data center operations. The prefecture’s climate, which is an average of 4 degrees Celsius cooler than that of Tokyo, is advantageous for server cooling—critical for maintaining data center performance. Furthermore, the region offers a relatively low risk of earthquakes, tsunamis, and flooding due to its inland location, coupled with excellent access to the metropolitan areas, making it a prime location for data centers.

Innovative Business Model for Operational Efficiency

This new venture employs a two-company system that separates asset ownership from operational management. AICore Grid LLC will take charge of the hardware assets, which include buildings, power supply, cooling systems, and racks. In contrast, AIS DC Services Co., Ltd. will focus on the operations, co-location services, GPU offerings, power contracts, network management, and maintenance monitoring.

By decoupling the ownership and operational functions, AI Storm can make agile decisions regarding capital investments, adapting to market conditions swiftly. Collaborations with financial institutions and other business entities also become streamlined under this model. Moreover, AI Storm aims to leverage its previous partnerships with established data center companies to enhance its operational capabilities, focusing on the design, construction, and maintenance of these facilities.

Mid-Term Vision — Connecting to a 50 Billion Yen Target

The AI infrastructure segment is fundamentally positioned for growth, benefiting directly from the increasing adoption of AI across various sectors. AI Storm has cultivated a strong perspective on this business segment through its expertise in AI education and product development, which will now also extend to the backbone systems of computing. The Nagano project symbolizes AI Storm's initial bold stride toward establishing itself as a key player in AI infrastructure.

Transitioning from AI services to AI infrastructure signifies a structural evolution for AI Storm. Through a divided operational model with SPC for asset management and AIS for operational execution, the company aims to build a robust portfolio of operational performance and investment to foster its core business in AI infrastructure.

The envisioned market cap of 50 billion yen is not merely an internal target; it represents a commitment to fortify the foundation of Japan's AI sector through strategic placement and significant advancements. AI Storm is determined to move forward decisively, fueled by ambition and innovation, towards this goal.
