Naoto Kan's administration has been beset by problems Japanese Prime Minister Naoto Kan has admitted that his political campaign fund received donations from a foreigner, in breach of Japanese law. Mr Kan told a parliamentary committee that at the time he had been unaware that the donor was a South Korean citizen, resident in Japan.
He told cabinet colleagues he would not be resigning.
Japanese law bans political donations from foreigners to prevent politicians being influenced from abroad.
Foreign Minister Seiji Mahara resigned earlier this month over donations he had received from a South Korean.
