Separated from his wife by a transparent barrier in a visiting room at the immigration detention center in Minato Ward, Tokyo, Colak touched it with his left hand to feel the warmth of her right hand. It was the closest they could get during their 30-minute visitation.

A 39-year-old Kurdish asylum-seeker who revealed only his last name for safety reasons, Colak has been detained in the Tokyo Regional Immigration Bureau since Jan. 11 of last year.

"This is just bullying. I did not do anything wrong. My kids are waiting for me to come back," Colak said in an interview with The Japan Times in mid-December.
