It seems that as for now Ozawa intends to stay and some of the DPJ members support him on this matter...The investigation should clarify the situation.
A different issue - today I listened to a lecture which was given by a Chinese academic on the state of current Sino-Japanese relations. In terms of foreign policy he credited Abe and Aso administrations for improving relationship with the PRC. He criticized China for refusing to have summit meetings with Koizumi and for not giving enough credit to Japan as a democratic and pacifist nation. On the other hand he also pointed out that Japan needs to rethink its attitude towards Taiwan and the history issue. I was just wondering whether some subsequent Japanese administration may do such thing....
