Your post's title says:
A foreign journalist detained, deported in relation to the Summit.
The fact the link you provided says:
Mis. Susan George was safely admitted the entry before the noon after the interview for three hours.
(The article has changed the hours of the interviews from 3 to 4 in the new edition.)
Japan Times JUST BE CAUSE Column 5: July forecast: rough, with ID checks mainly in the north
A reporter friend also reported that registered NJ Summit journalists are being detained at the border and deported.
Wow your own link says
Last night (June 27), three Hong Kong citizen journalists who have been registered with the Citizens’ Media Center (Sapporo) were detained by Immigration, and were on the verge of being deported.
This morning, Susan George (ATTAC France) was stopped and questioned at the airport. Hi Blog. Forwarding from Ms Kimura Kayoko, freelance writer for online independent internet newspaper Nikkan Berita
It means they were not deported, isn't it?
On a tangential note, you might be interested in the groups this Nikkan Belita quote to support their article?
