A spokeswoman for the Tokyo police says Shoichi Nakagawa was found dead Sunday in the bedroom at his Tokyo home. The cause of death was still under investigation.
She says other details are not immediately available.
Nakagawa caused an uproar when he appeared groggy at a news conference during the Group of Seven financial leaders in Rome in February. He resigned as finance minister in February, then lost his seat in parliament in Aug. 30 nationwide elections.
