A photograph of a 4-year-old girl caused quite a stir on the Internet due to a pair of legs that mysteriously appear standing behind her.

The photo, taken in July 2014 and later uploaded to Reddit, shows a girl standing on a beach in Japan with two booted feet appearing behind her legs. A small piece of blue cloth also peeks out from underneath her elbow.

Martin Springall, the girl's father, explained to ABC News that he took the picture during a weekend trip to Zushi beach when they used to live in Tokyo. He said the image has not been altered and that he didn't see anything behind his daughter when he snapped the photo.

"I took a few pictures, and when I was looking through them at night, I noticed what appeared to be a pair of boots behind her in one of the photos," Springall, whose family now lives in Canada, told the station.

"I took several of her in the same spot, but only one had the boots."

What the image doesn't show is that adjacent to the beach is a Samurai graveyard, leading many to speculate the mysterious feet belong to a Samurai ghost.

"Some thought it could be the ghost of a World War II sailor," Springall told ABC News.

His daughter also thinks the boots belong to a ghost.

"But not a scary ghost- a nice one," he said.
