In late summer 2009, 8-year-old Kianna Joanna Berg vanished from her home in Fairfax, Virginia, when she left with her older brother Gunnar on what their father, Douglass Berg, was told would be a vacation to Japan. Kianna is biracial (White and Asian), with brown hair and brown eyes, and speaks both English and Japanese. The departure was arranged by their non-custodial mother, Naoko Numakami (who may also use the last name Berg), and was later treated as a parental abduction rather than a consensual relocation.

A federal kidnapping warrant for Naoko Numakami was issued on October 15, 2010. Since the move to Japan, Douglass Berg has had no contact with Kianna or Gunnar, and they are believed to remain in Japan with their mother. Little else about their lives there is publicly known.

If anyone has information about Kianna, Gunnar, or Naoko Numakami’s whereabouts in Japan during or after 2009, please share what is known.
