Kagoshima Prefecture (Governor: Koichi Shiota), Satsumasendai City (Mayor: Ryoji Tanaka), Kyushu Electric Power Co., Inc., Circular Park Kyushu Co., Ltd., and Kai Shin Digital Infrastructure Inc. have signed a Memorandum of Understanding (MOU) to accelerate the early deployment of a large-scale AI Data Center (AIDC) project in Satsumasendai City, Kagoshima Prefecture.

This agreement aims to advance the development of next-generation AI infrastructure within the Circular Park Kyushu initiative, which seeks to redevelop the area surrounding the former Sendai Thermal Power Plant site into a new hub for sustainable industry and circular economic activities.

Through this partnership, the parties will collaborate in areas including power infrastructure, telecommunications, land development, and industrial policy, in order to promote the development and operation of a large-scale AI data center cluster in the region.

At the same time, the parties also discussed the future expansion of the data center project originally announced in September of last year. The project, initially planned at 350 MW, is now being considered for phased expansion to a maximum scale of 1,000 MW (1 GW).

Current Strategic Direction of the Project

Total Power Capacity

1,000 MW (1 GW)

Strategic Infrastructure Assets

The project aims to establish a demonstration model of advanced data center power infrastructure capable of supporting multiple high-voltage power systems, including dedicated 6 kV, 20 kV, and 220 kV power lines.

This infrastructure is designed to support the operational requirements of next-generation and future-generation AI data centers, including facilities optimized for high-density GPU computing environments.

Industrial Significance

The project seeks to foster the creation of a new ecosystem centered on AI data centers (AIDC), including industries related to:

• Power distribution and electrical infrastructure• Telecommunications equipment and networks• Advanced cooling technologies• Data center operations and maintenance• GPU hosting and colocation services

In addition, the initiative aims to cultivate new industry players specializing in GPU infrastructure management, while simultaneously promoting the development and training of highly skilled professionals to support the rapidly growing AI infrastructure sector.

Vision for the Satsumasendai AI Data Center Campus

The AI data center initiative in Satsumasendai City is envisioned as a strategic industrial hub following the success of the semiconductor cluster known as “Silicon Island Kyushu.”

The project aims to establish a large-scale AI infrastructure campus expandable up to 1 GW, positioning the region as a key center for next-generation digital infrastructure.

With access to stable and cost-efficient large-scale power supply and extensive land availability, the project will begin with an initial phase of 350 MW, followed by gradual expansion toward 1 GW capacity.

The infrastructure will incorporate a combination of container-type and traditional data center facilities, integrated with power distribution systems, energy storage solutions, telecommunications equipment, and advanced cooling technologies.

In addition to supporting the development and operation of large-scale AI models (LLMs), the project will also promote the integration of Physical AI technologies, applying AI to real-world industries such as robotics, manufacturing, logistics, and construction.

Through these efforts, the initiative seeks to foster the emergence of domestic Japanese players in the AI data center industry.

Regional Economic Impact

The development of large-scale AI data centers requires significant investments in power, telecommunications, and water infrastructure. At the same time, the installed facilities will generate long-term opportunities for maintenance, equipment replacement, and technical services, creating sustainable business opportunities for local companies.

Furthermore, the project envisions the potential establishment of AI server manufacturing facilities by Wistron, a global electronics manufacturer, alongside the development of port-based logistics and supply chain infrastructure.

These initiatives are expected to significantly enhance regional industrial capabilities and employment opportunities.

By realizing this project, the partners aim to demonstrate that even regional cities such as Satsumasendai can become centers for world-class advanced industries, providing a model for the geographical diversification of data center infrastructure across Japan.
