A new documentary that questions whether it is right to sacrifice a community's way of life for the betterment of the wider public has revealed the turmoil and hardships faced by those who were displaced in the wake of the 2011 Fukushima nuclear power plant disaster.

"Tsushima: Fukushima Speaks Part 2," directed by freelance journalist Toshikuni Doi, features the testimonies of people seeking the return of their hometown, which was deemed uninhabitable for a century after the world's worst nuclear accident since the 1986 Chernobyl meltdown.

The documentary explores the story of a minority group that must endure suffering for the happiness and convenience of others, a theme of global resonance, with Doi, 71, explaining that the film focuses on the impact the accident had on the daily lives of people forced to leave their homes.
