In accordance with a ruling from a citizen's panel last year — and despite two previous refusals by Tokyo prosecutors to press charges — the three will be the first to go to court over the catastrophic meltdown, which followed a massive tsunami.

Those charged include former TEPCO chairman, Tsunehisa Katsumata, and former executive vice presidents, Sakae Muto and Ichiro Takekuro, according to Reuters. As their indictments did not stipulate arrest, none of the trio have been taken into custody.

Despite previous claims there was insufficient evidence necessary to prosecute, a unique component of the country's legal system allowed citizens to make the final call.
