New AI-ready data centre opens

A data center is just a warehouse full of computers, but the new ones being built for artificial intelligence look more like power plants with server racks inside. NTT DATA said on April 9, 2026 that it has opened the Keihanna OSK11 facility in Kyoto, Japan, as a site built for cloud and artificial intelligence workloads. (nttdata.com) Artificial intelligence work strains a building in two ways at once: it pulls huge amounts of electricity and it throws off huge amounts of heat. NTT DATA says OSK11 uses high-efficiency cooling and an “AI-ready technical roadmap” so it can handle denser computing equipment than older enterprise server rooms were built for. (services.global.ntt) This is not a small server closet for one company. NTT DATA says the site can deliver up to 30 megawatts of information-technology load, which is enough capacity that the company is pitching it to hyperscalers and large enterprises expanding in Japan. (services.global.ntt) The building itself is sized like a serious industrial project. NTT DATA’s Japan site says OSK11 opened in February 2026, has four floors, about 10,900 square meters of server-room space, and room for as many as 3,800 racks. (nttdata.com) The location is part of the pitch. The data center sits in Seika, Kyoto Prefecture, inside the Keihanna area between Kyoto, Osaka, and Nara, and NTT DATA says that corridor is becoming a second core region for large-scale data center demand in western Japan. (nttdata.com) Companies like NTT DATA are also selling resilience, not just raw computing. The company says OSK11 uses a base-isolated structure for earthquakes, Tier III-equivalent redundant power and cooling systems, three building entries for network lines, and on-site fuel storage for 48 hours of backup generation. (nttdata.com) The artificial intelligence angle shows up in the cooling plan. NTT DATA says the site can accommodate direct liquid cooling, which moves heat away with fluid instead of relying only on cold air, the same basic shift you see when a car radiator cools an engine more efficiently than just wind alone. (nttdata.com) NTT is tying the building to its own network strategy too. The company says OSK11 sits next to NTT Group research facilities and can connect through the Innovative Optical and Wireless Network’s all-photonics network, which NTT is developing as a faster link between data centers. (nttdata.com) That helps explain why this opening is getting attention. Data Center Dynamics reported that OSK11 is NTT’s 14th data center in Japan, and the company is opening it at a moment when cloud providers and artificial intelligence customers are hunting for sites with enough power, cooling, and fiber to run heavier computing loads. (datacenterdynamics.com) So the story here is not just one new building in Kyoto. It is that artificial intelligence is turning data centers into specialized infrastructure, and companies now market floor area, megawatts, cooling method, seismic design, and network links the way chip companies market processor speed.
