The Tokyo High Public Prosecutor's Office summoned Kazuyoshi Miura, whose conviction in connection with the murder attempt on his late wife became final, and took him into custody, sources said.
The Supreme Court upheld a lower court ruling on Sept. 16 that sentenced Miura to six years in prison, and his appeal against the top court's decision was dismissed Oct. 6.
Miura will be sent to the Tokyo Detention House for health and other checks before being moved to a prison, sources said Monday. He will remain in prison for another two years and two months, as his detention period will be subtracted from the six-year term.
Miura also was accused of being involved in the murder plot of his wife. Three months after the murder attempt for which Miura has been convicted, Kazumi Miura, 28, sustained a gunshot in Los Angeles in 1981, from which she died a year later.
But the Tokyo High Court acquitted him in the case and released him from detention in July. The high public prosecutors' office has appealed the case to the Supreme Court.
