Existing buildings,
into next-generation AI infrastructure.
Beyond constructing dedicated data center buildings from the ground up, ICHIKOSHI CO., LTD. is advancing a new business model that uses space in existing buildings, hospitals, universities and corporate facilities to introduce HAI data center capabilities.

In the usable space of existing buildings, we aim to combine power, network, cooling and AI/GPU compute, and to bring HAI data center capabilities closer to the people who use them.
Existing real estate × Power × AI/GPU × Network × Users
= A new kind of AI infrastructure
For hospitals, education and enterprise — and for real estate.
Hospitals and medical institutions
AI compute for medical AI, image analysis and research, placed inside the hospital or in an existing facility next to it.
Universities, education and research
GPU and AI compute environments for research, teaching and industry–academia collaboration, placed in existing facilities.
Enterprises
We propose AI infrastructure to support generative AI, internal data use, AI-driven process change and new AI services.
Building owners and real estate operators
We aim to reassess usable floors and units in existing buildings as AI infrastructure, creating new property value and new business opportunities.
Toward establishing intellectual property rights for our own system.
A system for installing data centers using space inside existing buildings
ICHIKOSHI CO., LTD. has filed patent applications covering the proprietary system behind this business and is working to establish intellectual property rights in Japan and abroad. Because that work is still under way, this page does not disclose the details at the core of the technology.

From cities to the whole country. Building a network of distributed AI infrastructure.
Putting local assets to work — hospitals, universities, enterprises, existing buildings — to place the AI compute that is needed where it is needed. ICHIKOSHI CO., LTD. aims to deploy HAI data centers nationwide not as buildings, but as operating infrastructure supporting society, healthcare, education and business.
Shall we develop the HAI data center business together?
We welcome enquiries about deployment, joint ventures and facility use from hospitals, universities, enterprises, building owners, real estate companies, AI/GPU operators, power-sector businesses and investors.
