The popular thread attracted the attention of many readers from outside the 2channel community, and the November 2007 issue of MU magazine, a Japanese publication devoted to the study of paranormal phenomena, featured an article about the Antarctic humanoids. The article speculated on the possibility of unidentified creatures inhabiting the southern seas, and it included a Google Earth screenshot showing what looks like a Ningen in the South Atlantic Ocean off the coast of Namibia. To date, no solid evidence has been presented to confirm the existence of the Ningen. The government is believed to have kept detailed records of the sightings, but they have released no information to the public and have reportedly instructed eyewitnesses to remain silent.
Ningen sightings seem to occur most frequently at night, making them all the more difficult to photograph. In still images, the sea cryptids mostly just look like icebergs, though it is said that their smooth, human-like skin can be seen when the photographs are enlarged. In any case, no convincing photographs have been made public, either because they do not exist or because, as some argue, the government does not want to invite undue scrutiny and tarnish the scientific reputation of the whale research program.
