The exact exchange is as follows :
Journalist : There was a news recently that 3% of the mansion buyers in the major cities were from abroad or foreign. What do you think about that?
Onoda : Is that an official statistic? Isn't that just an news article? I can't comment on it unless it's an official statistic.
Journalist : Ok. Thanks

記者「海外の人の新築マンション購入が東京都は約3%に留まるとの報道があるがこの調査を元にどう規制をお考えか」
小野田紀美大臣「その数値は正式なところからですかね？報道ベースですよね？報道ベースの時点で私から今お答えすることはございません」
This video is circulating around JP Twitter as "Onoda owns Journalist". But she's absolutely wrong here. It is an official statistic from Ministry of Land and Infrastructure – in fact, it was probably given to her prior to this meeting.
