TOKYO -- Japan's retail energy market was liberalized at the beginning of the month. As of April 8, 622,700 Japanese households had switched electricity providers, with more than 60% of the total affecting Tokyo Electric Power Company Holdings, better known as Tepco.
According to the Ministry of Economy, Trade and Industry, Greater Tokyo's retail energy market will amount to about 2.8 trillion yen ($25.3 billion). If new entrants gain market share, they could hold down Tepco's bottom line.
