The Tokyo Electric Power Company, commonly known as TEPCO, is one of Japan's largest electric utility companies. Founded in 1951, it provides electricity to the Kanto region, which includes Tokyo and its surrounding areas. TEPCO plays a crucial role in Japan's energy supply, operating numerous power plants and managing the electrical grid. In March 2011, TEPCO faced a significant crisis when the Fukushima Daiichi nuclear disaster occurred following a massive earthquake and tsunami. This incident raised concerns about nuclear safety and led to changes in Japan's energy policies. TEPCO has since focused on improving safety measures and transitioning towards more sustainable energy sources.
