Prime Minister Yoshiro Mori on Sunday night appointed former Economic Planning Agency chief Hideyuki Aizawa to replace scandal-hit FRC chief Kimitaka Kuze as the nation's top financial regulator.

Aizawa, 81, accepted the post of chairman of the Financial Reconstruction Commission after Mori called him into the Prime Minister's Official Residence to request he take the position.

After accepting Mori's offer, an attestation ceremony was held at the Imperial Palace to affirm Aizawa's position as the new FRC chief.
