 Chisako Kakehi  is accused of using cyanide to kill  her  lovers and make millions from insurance payouts.  Her  lawyers plan to appeal the sentence.
Prosecutors said  she  targeted wealthy men who were mostly elderly or sick.
 She  became known in Japanese media as the Black Widow  after the female spider which kills its mates after sex.
Kyoto District Court ruled that Chisako Kakehi used cyanide "with a murderous intention" in the four cases  and that  she  should be held responsible for the crimes even though  she  had been diagnosed with dementia.
 Kakehi   who was wearing a hearing aid and asked the judge to speak loudly during the proceedings  showed no emotion when the sentence was handed down.
 Ms Kakehi  was accused of murdering  her  fourth husband  75-year-old Isao Kakehi  on 28 December 2013  a month after they got married.
 She  was also accused of killing two other boyfriends  aged between 70 and 80  and the attempted murder and robbery of another boyfriend - who later died of cancer - between 2007 and 2013.
The trial heard that  she  had joined matchmaking services in which  she  had specifically requested to meet men who were rich and childless.
 She  reportedly inherited around one billion yen ($8.8 million) in all  although  she  later lost some of it through the stock market.
During the 135 day trial  Kakehi  appeared to admit killing  Isao Kakehi   saying  he  had not treated  her  well financially  but later retracted it.
 Her  lawyers said at the time that  her  testimony could not be trusted because of  her  dementia. They have appealed against the death sentence to a higher court  arguing that  her  dementia means  she  cannot be held criminally liable.

"Petrocaribe will be strengthened -- independent of the international situation  independent of the price of oil " Venezuela President Hugo Chavez said as he arrived Friday in St. Kitts.
 His country's state Bolivarian News Agency said Petrocaribe leaders meet "with the expectation of its expansion  as well as new programs of cooperation and attention to a world increasingly thirsty for fuel."
 During the meeting  Chavez called the pact a geopolitical and social "offensive for unity " and said Venezuela is open to accepting other nations. "If some countries want to join  the doors are open " he said.
 The plan promotes Chavez's vision of regional independence from the United States  and the lure of cheap oil has drawn countries friendly to Washington as well as his leftist allies.

Sen. Al Franken  who on Thursday admitted he had "crossed a line" with some women   was questioned about  his  behavior 18 years ago â by shock jock Howard Stern.
Stern asked  Franken   not yet a U.S. senator  if  he  had grabbed TV personality Kathie Lee Gifford's rear end during  his  radio show in 1999. A caller had prompted the question.
"She grabbed my ass "  Franken  responded.

"I certainly did not touch  her  in any way to arouse or gratify "  Franken  would add.
Last week  the Minnesota lawmaker was accused of sexual misconduct by radio host Leeann Tweeden who said he forcibly kissed and groped  her  in 2006.
Another woman said  Franken  grabbed her rear end when they posed for a photo four years later  and two women told the Huffington Post  he  touched their buttocks 10 years ago.
"I feel terribly that Iâve made some women feel badly and for that Iâm sorry  " Franken  said Thursday.
