The United States has confirmed that 35 Japanese war criminals are banned from entering the U.S.
That's more than double the 16 previously reported.
U.S. Justice Department spokesman Peter Carr provided the new figure in an interview with Korea's Yonhap News Agency, although he declined to give any more details about those who are on the list.
Sources say roughly 20 belonged to Japan's infamous unit 7-3-1, which carried out horrifying experiments on live human subjects during World War Two.
Most of the others were related to the establishment of "comfort stations," or military facilities where women were forced into sexual slavery by the Japanese military.
The list of Japanese war criminals banned from entering the U.S. was first established in 1996.
