Japanese ISP Optage is to deploy liquid-cooled containerized data centers equipped with GPUs for AI training.

The company this week announced it will deploy container-type data centers for generative AI in Mihama-cho, Fukui Prefecture, by the end of 2026.

This facility will offer customers dedicated "AI training servers" equipped with liquid-cooled GPUs. The company said the energy to power the container with be derived from nuclear sources.

Further details weren’t shared.

In 2023, Optage announced plans for a new 14-story data center in Osaka. The facility is set to launch in 2026. The company is pitching the container site for AI model training and the Urban Connectivity Data Center (OC1) for inferencing.

With roots back to 1988 and wholly owned by the Kansai Electric Company (KEPCO), Optage provides telecommunications services throughout the Kansai region.

Previously known as K-Opticom, with K Square Co and then Kanden System Solutions as the data center business, the company provides Internet, telephone, and TV services using its own fiber network, and also operates as a Mobile Virtual Network Operator (MVNO).

On its website, Optage said it operates the Umeda North Data Center in central Osaka, launched in 2012, and the Shinsaibashi Data Center, again in central Osaka which launched in 2008.

Another Umeda Data Center was ‘renewed’ in 2009; a post from 2011 said the company operated facilities in Osaka city [Umeda, Umeda North, Shinsaibashi, Shinmachi], Kyoto [Karasuma], Hyogo [Kobe, Himeji], Nara [Nara], Shiga [Otsu], and Wakayama [Wakayama].

Optage owner KEPCO is also partnering with CyrusOne to develop data centers across Japan.

KEPCO operates three nuclear power stations in Fukui Prefecture: the 780MW Mihama plant, the 2.2GW Ōi plant, and the 3.39GW Takaham plant.
