Six companies, including abc, ReYuu Japan, Image One, Wintest, FD, and Birdman, have completed the establishment of a joint venture named AI Data Partners. The company was formally incorporated on June 24, 2026, with a capital of 15 million yen. AI Data Partners will focus on planning, designing, developing, constructing, owning, managing, and maintaining AI-specific high-performance data centers. The venture aims to address the growing demand for AI infrastructure in Japan, leveraging the partners' strengths in financing, land acquisition, power supply, AI solutions, maintenance, and branding. The company plans to set up project-specific special purpose companies (SPCs) under the joint venture to acquire and operate data center assets across up to 10 domestic locations, targeting an internal rate of return of 6% or more. The board includes representatives from each partner company, and Hiroyuki Kishi, a professor at Keio University Graduate School of Media Design, is slated to serve as an auditor. The joint venture was preceded by a memorandum of understanding in April and a formal resolution in May.
The joint venture is registered at Akasaka 4-9-17 in Minato-ku, Tokyo. Its representative director is Tomoki Katada, who also serves as vice president of abc. Ownership is split with abc and ReYuu Japan each holding 30%, and Image One, Wintest, FD, and Birdman each holding 10%.
The board includes six directors: Katada, Kenichi Shigesumi (ReYuu Japan executive officer), Ayumu Kawakura (Image One president), Masayasu Higuchi (Wintest senior managing director), Masashi Suzuki (FD president), and Motohiro Yoshikawa (Birdman president). Three auditors were appointed: Akiaki Yabuta (ReYuu Japan director), Yoshiyuki Tsuda (abc employee and Image One director), and Hiroyuki Kishi (abc advisor and Keio University professor). The summary named only Kishi.
AI Data Partners has also signed a memorandum of understanding with KAYTUS to build a supply framework for high-density, high-efficiency next-generation AI computing equipment. The company's business scope extends beyond data center planning and operation to include renewable energy equipment sales, leasing, installation, and consulting, as well as securities acquisition, holding, and disposal. The fiscal year ends March 31. Total contributed assets are 30 million yen, comprising 15 million yen in capital and 15 million yen in capital reserves.
The joint venture is an equity-method affiliate for both abc and ReYuu Japan. The press release frames the venture as a response to Japan's need for domestic high-performance computing resources to support economic security and digital transformation.
