Tokyo Electric Power Company Holdings, known as TEPCO, is Japan's largest electric power company, supplying electricity to the greater Tokyo metropolitan area and surrounding regions. The company operates thermal, hydroelectric, and nuclear power generation facilities and manages an extensive transmission and distribution network. TEPCO has been undertaking a long-term reconstruction and financial rehabilitation program, with the Japanese government holding a significant ownership stake as part of the recovery framework.

For international investors, Tokyo Electric Power Company Holdings — TEPCO — is Japan's largest electric utility, serving the Tokyo metropolitan area. The company continues to navigate the long-term consequences of the Fukushima Daiichi nuclear accident, managing decommissioning operations, compensation liabilities, and the ongoing costs of reconstructing its generation and transmission infrastructure. TEPCO's investment case is inherently complex, with regulatory, legal, and operational risks that are distinct from conventional utilities, making it a specialized holding for investors with a specific view on Japan's nuclear and energy policy trajectory.
