Mitsubishi Corporation and JFE Holdings, Inc. have signed a second memorandum of understanding (MOU) to advance a joint project integrating a power business and a data center in the Ohgishima area of Japan’s Keihin District.

The agreement builds on an initial MOU signed in March 2025, under which the companies evaluated the feasibility of the project alongside MC Digital Realty, Inc., a data center developer and operator.

The planned development will utilize approximately five hectares of land adjacent to JFE’s captive power plant, which has a generation capacity of 190 MW. The site is expected to support at least two data centers, with an initial 60 MW facility targeted to begin operations in fiscal year 2031.

The companies plan to establish a joint venture to move the project into a more concrete phase, including land development, infrastructure planning, and data center construction to support cloud and AI computing demands.

According to the companies, the project leverages the area’s proximity to central Tokyo and access to stable power. Future expansion is expected, potentially forming a data center campus with several hundred megawatts of IT capacity.

The initiative also explores the use of green energy, including hydrogen, as part of broader efforts to support sustainable and stable power supply. Both companies stated the project aims to address rising demand for data centers while contributing to Japan’s industrial competitiveness and sustainability goals.
