TEPCO Ventures

Shinji Akatsuka serves as President and CEO of TEPCO Ventures, reporting into Tokyo Electric Power Company Holdings. While the firm does not publicly disclose its full investment committee, Akatsuka is the named decision-maker in public records. Momoko Nagasaki, formerly Chief Innovation Officer at the venture unit, now holds the Executive Vice President role at the parent company, indicating tight integration between venture strategy and group-level capital allocation.

TEPCO Ventures is a wholly owned subsidiary of Tokyo Electric Power Company Holdings, Japan's largest electric utility. It functions as the group's dedicated corporate venture capital arm, investing TEPCO's balance-sheet capital into early-stage companies whose technologies can be deployed across the parent's generation, transmission, and retail operations. The relationship gives portfolio companies direct access to one of the world's most complex power grids for pilot projects.

Per public record, TEPCO Ventures focuses on early-stage startups—venture and seed-stage companies with technologies relevant to energy transition, grid modernization, and industrial automation. The unit does not publicly disclose a strict stage boundary, but its known engagements suggest a preference for companies with prototypes ready for field testing on TEPCO infrastructure.

TEPCO Ventures concentrates primarily on the Japanese startup ecosystem and is a member of the Japan Venture Capital Association. However, given the parent company's international consulting operations and partnerships across Southeast Asia, the unit can create pathways for portfolio companies to expand regionally. No publicly disclosed non-Japanese portfolio companies have been confirmed.

TEPCO Ventures has explored bitcoin mining as a mechanism for using curtailed renewable energy that would otherwise go to waste. The approach mirrors strategies tested by other utilities that treat proof-of-work mining as a flexible demand-response asset, absorbing excess generation during periods of low grid load. The subsidiary Agile Energy X, led by Kenji Tateiwa, focuses on adjacent grid-optimization commercial models.

TEPCO Group operates the Fukushima Revitalization Efforts, a philanthropic initiative focused on economic recovery in communities affected by the 2011 nuclear accident. This foundation operates separately from TEPCO Ventures' investment activities and does not influence venture capital allocation decisions.

The defining structural feature is its captive pilot environment: startups selling grid hardware or software can deploy directly onto TEPCO's live transmission and distribution network. This real-world testing ground—one of the most disaster-hardened grids globally—functions as both a diligence filter and a scaling accelerator, a deployment pathway most corporate VCs cannot offer.
