Netflix has a new four-part series called "Encounters," dealing with sightings of the paranormal. Episode 4 is entitled "Lights Over Fukushima." At about the 28:40 mark, we have an interview with one of the workers involved in the cleanup of the 2011 tsunami in Japan that knocked out the Fukushima nuclear power plant. He says this:
"When we were searching for people in the aftermath, usually when we checked cars, we would see these bright blue-white lights kind of hovering above a spot like this. They seemed to be floating over where someone had died....In Japanese folklore there's something called a hitodama, it's like a fireball or a bright ball of light that floats in the air. At the time I saw a number of them out there. It's believed that when a person dies, their soul ascends to heaven as a hitodama, a fiery ball of light. I find it hard to believe that, in the aftermath of catastrophes like these, when so many lives are lost, most people would see these balls of light as UFOs. I think most of us would interpret these things as hitodama, the lingering presence of the human soul."
A web page tells us this about such hitodama:
"Appearance: Hitodama are the visible souls of humans detached from their host bodies. They appear as red, orange, or blue-white orbs, and float about slowly not too far from the ground.
Behavior: On warm summer nights, these strange, glowing orbs can be seen floating around graveyards, funeral parlors, or the houses where people have recently died. Most often they are seen just before or after the moment of death, when the soul leaves the body to return to the ether. It is most common to see them at night, though they occasionally appear during the daytime. Rarely, hitodama materialize when a person loses consciousness, floating outside of the body, only to return when the person regains consciousness."
