Visiting overseas nuclear experts on Saturday urged Japan to create a culture of safety among its power companies and energy industry regulators, calling this the best way to avoid another nuclear disaster.

"The most fundamental obligation perhaps is to establish an appropriate safety culture among all those involved in nuclear enterprise," Richard Meserve, former chairman of the U.S. Nuclear Regulatory Commission, told a news conference in Tokyo.

A two-day meeting between the overseas experts and an independent panel created by the government to investigate the Fukushima nuclear crisis ended earlier the same day.
