Prosecutors demanded a 20-year prison term for Kaori Mihashi on Thursday for murdering and dismembering her husband in December 2006 and disposing of the body parts around Tokyo.
The 33-year-old housewife stands accused of fatally striking her husband, Yusuke, with a wine bottle and cutting up his body using saws and kitchen knives.
Prosecutors alleged that Mihashi killed her husband in a fit of anger because she was unable to proceed with divorce talks the way she had hoped.
