Tokyo gov. sought 100 mil. yen from scandal-hit hospital group: source
Before running in the December 2012 gubernatorial election, Tokyo Gov. Naoki Inose sought 100 million yen from a hospital organization later at the center of a fraud scandal, a source close to the hospital group said Saturday, challenging the governor's claim that he never asked for money.
On Friday, Inose admitted he borrowed 50 million yen from the Tokushukai hospital and medical facilities chain.
"I did not say anything about the amount of money," Inose told reporters Saturday, denying he asked for 100 million yen.
