The 10 electric utilities nationwide say they expect to reduce rates by ¥200 to ¥600 in May from a month earlier, thanks to falling fuel costs.

Tokyo Electric Power Co. said the average household bill in Tokyo could fall between ¥500 to ¥600. Among other areas, customers in Kyushu, Shikoku and the Chubu and Hokuriku regions are expected to save around ¥200, according to local utilities.
