There’s a touch of Hollywood in this dramatised account of the 50 workers who stayed at Fukushima Daiichi in an attempt to avert catastrophe

Dangerously high concentrations of politeness are observed in this dramatisation of the 2011 disaster at the Fukushima Daiichi nuclear power plant. Not only do most of the heroic “50” left behind to avert nuclear catastrophe constantly apologise for underperforming in acts of barely believable self-sacrifice, at one point a manager begs forgiveness for refusing to allow two employees to re-enter the radioactive zone after a failed first attempt. To the feckless western mind more likely to view Homer Simpson as the standard-issue nuclear power-plant employee, it’s a relief when – just for a second – a few Fukushima workers contemplate running away.

It is possible director Setsurō Wakamatsu has taken the Hollywood route in portraying the staff as so infallibly courageous – though Fukushima 50 is adapted from journalist Ryusho Kadota’s book, which investigated the response to the earthquake and tsunami in more than 90 interviews. Possibly to avoid lawsuits from Tokyo Electric Power Company executives portrayed here as selfish and shamefully caught on a back foot, everyone in the film is fictionalised – except for prime minister Naoto Kan, though he is never referred to by name, and plant manager Masao Yoshida. Yoshida crucially defies orders and allows the reactors to be cooled with seawater – which prevented meltdown and the possible devastation of Japan’s entire eastern seaboard. The reactors also must be “vented” for pressure manually by workers agonisingly selected for the task. Played by Ken Watanabe as a man having the ultimate bad day at work, the simmering Yoshida looks in need of a similar intervention.
