The Tokyo Regional Immigration Bureau told an undocumented Filipino couple in Warabi, Saitama Prefecture, on Friday that they will be detained unless they decide by March 9 whether to leave Japan with or without their 13-year-old Japan-born daughter.

The bureau also told them their provisional release, which has been extended four times since November, will no longer be extended.

"I'm disappointed," said Arlan Calderon, 36, the girl's father. "I still don't know how to tell her."
