Now it appears one may have been captured on camera after eerie footage emerged of what some suggest is a female ghost following a man into a cab.
In the viral clip, a male passenger is seen walking towards a white cab at a Japanese taxi rank, when a black shape appears to follow him.
Some viewers have suggested it looks like a woman in a black hood.
The mysterious shape seems to glide behind the passenger into the taxi, before the vehicle closes with them both inside.
As the figure gets closer to the open door it appears to form more clearly, as a woman in a long robe and hood.
The 'spirit' even appears to pass through the closing door, some viewers claim.
The taxi then drives off, with viewers left wondering if the driver or passenger are aware of the extra fare.
