About this data

Number of customers switching electricity retailer during the month, by direction of the switch and by supply area. Monthly from April 2016, when Japan's retail electricity market was fully liberalised. Former regional utilities (みなし小売電気事業者) are the retail arms of the ten incumbent power companies; new entrants (新電力) are all other registered retailers. Extra-high and high voltage are industrial and commercial customers; low voltage is households (lighting) and small businesses (power).
