AI Storm Launches AI Data Center Business in Nagano Prefecture

## AI Storm Launches AI Data Center Business in Nagano Prefecture

AI Storm Co., Ltd. (formerly Gexeed Co., Ltd.; Head Office: Chiyoda-ku, Tokyo; President: Toshio Imai; Securities Code: 3719) announced that on May 20, 2026, it established AICore Grid LLC, a Special Purpose Company (SPC) to hold assets, and AIS DC Services Co., Ltd., a data center operating company, for the purpose of launching its AI data center business in Nagano Prefecture.

Both companies will promote the data center business by separating asset ownership and operations. The group is accelerating its structural evolution from a provider of AI services to an AI infrastructure company that supports the very computational foundation of the AI industry.

## Background

In April 2025, the company changed its trade name to 'AI Storm' and announced a mid-term management plan aiming for a market capitalization of 50 billion JPY within three years. Since then, it has been focusing on its AI business. The establishment of this SPC and the data center operating company is a key measure toward achieving this goal.

The context for this is the rapid expansion of demand for AI infrastructure and the geographic concentration of data centers in Japan. As generative AI becomes integrated into society, data center capacity and GPU computational resources are globally strained. While the Japanese data center colocation market is projected to reach 1.7817 trillion JPY by 2029, over 80% of domestic data centers are concentrated in the Tokyo and Osaka areas, making the development of core hubs in regional areas a national policy issue.

The company views this structural supply-demand gap as a business opportunity and has decided to construct and operate an AI data center utilizing a former factory site in Nagano Prefecture. Nagano Prefecture offers a cool climate, with an average annual temperature 4℃ lower than Tokyo, which is advantageous for server cooling. In addition, it is located inland, offering relatively low risks of earthquakes, tsunamis, and floods, and provides good accessibility from the Tokyo metropolitan area, making it a region with high potential for data center location.

## Agility in Operations and Investment through a Two-Company Structure

To promote this project, the company has adopted a structure that separates asset-holding functions from operational functions.

AICore Grid LLC (the SPC) will hold and manage hardware assets such as buildings, power facilities, cooling systems, and racks.
AIS DC Services Co., Ltd. (the data center operator) will be responsible for facility operations, colocation, GPU service provision, power contracts, network operations, and maintenance/monitoring.

Separating asset ownership and operations allows for agile decision-making on the timing and scale of capital investments, and makes it easier to structure collaborations with external financial institutions and business corporations.

Furthermore, the company will leverage its relationships with major data center-related business corporations with whom it has formed business alliances in the past, advancing collaboration in highly specialized areas such as data center design, construction, operations, maintenance, and monitoring. This will allow the company to achieve both rapid business launch speed and operational quality, realizing early monetization.

## Mid-term Vision: Connecting to a Market Capitalization of 50 Billion JPY

AI infrastructure is a stock-type revenue business area where demand accumulates as corporate use of AI expands. The company brings the perspective of a business participant cultivated through providing AI education, AI products, and AI agents to the side of the computational foundation—the data center. The Nagano Prefecture project is a strong first step for the company to step into this area as a provider of AI infrastructure.

From AI services to AI infrastructure—the company is taking the step forward from the specific site of Nagano Prefecture. Under the division of labor between the SPC (asset holding) and the operating company, the company will build up operating records and operational investments, growing the AI infrastructure business into the core of the group.
