Bikash Mohanty made these suggestions to Japanese lawmakers at a public discussion in the Japanese Parliament building, a Greenpeace statement said.
Japan is in the process of amending the Act on Compensation for Nuclear Damage, 1961 after it realised that the supplier of nuclear reactor could not be held responsible under its weak liability laws.
The nuclear liability regime must provide for supplier liability to keep this balance so that all the benefactors of this dangerous enterprise share the devastating effects of nuclear disaster as a common burden, Mohanty was quoted as saying by Greenpeace.
Kazue Suzuki, a Greenpeace Japan campaigner, said Japan must follow India's example, make all nuclear companies fully accountable for the damage they cause, and put its people before industry profit.
