Tokyo: A prominent Nigerian asylum seeker and activist is being held in solitary at a Tokyo detention centre, a case that has highlighted a growing crackdown on foreigners living in Japan without visas and prompted demands for her release.
Elizabeth Aruoriwo Obueza was detained two weeks ago after authorities turned down an appeal against her asylum rejection, Obueza and her lawyer told Reuters.
Obueza, 48, campaigns for asylum seekers and the 4,700 people on "provisional release" from immigration detention - a status that lets foreigners out from detention but bars them from working and travelling freely.
Obueza`s arrest is part of a wider campaign by the Justice Ministry, which in September 2015 said it would take steps to reduce the 60,000 foreigners living in Japan without visas.
People on provisional release, many of whom have lived in Japan for decades, have been among those targeted, activists and lawyers say.
"Elizabeth was targeted and detained for being an activist," said immigration lawyer Shoichi Ibusuki. "I want her released immediately."
The crackdown on people like Obueza comes even as people on provisional release, despite being legally unable to work, power Japan`s construction and manufacturing sectors as companies scramble to find workers in the worst labour shortage in decades.
"Elizabeth is held in solitary because she`s an activist and immigration officials don`t want her causing trouble," said Mitsuru Miyasako, head of the Provisional Release Association in Japan, a group representing refugees and immigrants.
"Locking someone up alone in a tiny room is to ruin them psychologically."
Naoaki Torisu, a senior Justice Ministry official overseeing immigration detention, declined to comment on Obueza`s situation, saying he could not discuss individual cases.
Obueza, an evangelical Christian, said she fled Nigeria for Japan in 1991 to escape female genital mutilation and applied for asylum in 2011.
Obueza told Reuters she was locked up for more than 22 hours a day. Typically, detainees at the Tokyo Immigration Bureau, where she is held, are locked up for 18 hours a day, according to the Justice Ministry.
"I want to help people," Obueza told Reuters from across a security divide in a small meeting room at the detention centre. "Give me the right to help people - don`t put me in here."
During her previous 10-month arrest in 2011 at a different centre, Obueza organised detainees to write a petition to immigration authorities calling for better medical care, Miyasako said.
For more than a decade, Obueza has visited immigration detention centres across Japan, helping detainees navigate the asylum system and find legal help, said rights groups, lawyers and former detainees.
"She has supported so many people as an activist and that`s a nuisance for the immigration authorities," said Miyasako, who has worked with Obueza, adding that she had helped hundreds.
Former detainees and people on provisional release visit her in detention every day, sometimes waiting for hours, he said.
Solitary cells, usually for detainees who are ill, unruly or have tried to harm themselves, are about five square metres, detainees say.
In 2014, a Sri Lankan man died in a solitary cell at the same centre, highlighting problems with medical care.
Isolation has not stopped Obueza from fighting for detainees` rights.
"When I go outside my room, I go around the windows and talk to the others," Obueza said. "I advise them."
Obueza said of the immigration officials who locked her up: "You might think you arrested me, but I think God wants me here to help some other people."
