Japan will look at other countries as it studies the idea of spinning off power distribution from the business of electricity generation, a move that would put an end to power companies' regional monopolies, Chief Cabinet Secretary Yukio Edano said Thursday.

"The government has a large responsibility in securing a steady supply of electricity," Edano said.

"But looking at other countries, there are various forms, and I think that we will move forward with discussions while referring to examples including from abroad," he said.
