Based on his own experience working in the nuclear power industry, Ichio Isobe, 92, is gravely concerned by moves to reactivate Japan's idled reactors.

"Given its small national land, people won't have a place to live if an accident like the (March 2011) Fukushima No. 1 nuclear plant occurs again," said Isobe, a stern opponent of a proposal to build a nuclear plant on the Inland Sea coast in Yamaguchi Prefecture.

Isobe lives on Iwai Island, a small island off that coast.
