TEPCO, or Tokyo Electric Power Company, is one of Japan's largest electric utility companies. It provides electricity to the Kanto region, which includes Tokyo and its surrounding areas. Established in 1951, TEPCO plays a crucial role in Japan's energy supply and infrastructure. In March 2011, TEPCO gained international attention due to the Fukushima Daiichi nuclear disaster, which occurred after a massive earthquake and tsunami. The incident raised concerns about nuclear safety and led to significant changes in Japan's energy policies and regulations. TEPCO has since focused on improving safety measures and transitioning to more sustainable energy sources.
