The government hopes a Japan-born Filipino girl and her undocumented parents, who face deportation, decide by Friday to either leave the country together or part ways as the teen stays behind, Justice Minister Eisuke Mori said Tuesday.

"(We hope the family) will reveal their intention in response to advice given to them by the immigration authority," Mori said.

His remark came a day after immigration authorities took the father, Arlan Calderon, 36, into detention at the Tokyo Regional Immigration Bureau, when he and his wife, Sarah, 38, presented themselves to seek special permission for the family to continue residing in Japan together.

On Monday, immigration authorities allowed Sarah Calderon and their daughter, Noriko, 13, who attends a junior high school in Warabi, Saitama Prefecture, to stay in Japan for another week, but requested that they report on their decision by Friday and come to the bureau again next Monday.

But the authorities warned that the family, including the girl, could all be placed in detention Monday and deported the following day if they do not respond to the choices presented to them.

The Justice Ministry and the immigration authority have repeatedly told the couple that their daughter alone could be granted special permission to stay in Japan.

The family has continued to seek special permission for all three of them on grounds that the daughter can only speak Japanese and is too young to be on her own.

Arlan Calderon came to Japan in May 1993, a year after his wife did. Both entered the country on passports of different people and stayed undetected. Their daughter was born in 1995.
