His bereaved wife Chisako was inconsolable when police interviewed her.
Given his age, the police were quite ready to close the case as a natural death until a sharp-eyed detective began to suspect Mrs Kakehi, 70: Could the grieving widow, who looked more like your neighbourhood granny, be a money-grabbing murderess instead?
Kakehi was born Chisako Yamamoto on Nov 28, 1946, growing up in a middle-class family in Kitakyushu city, Fukuoka, where her father worked in a steel factory.
Kakehi - dubbed the Black Widow by Japanese media - killed her lovers with health capsules that had been laced with cyanide.
Her lawyers have appealed against the "unjust" sentence on the grounds of diminished responsibility as she has early-stage dementia, and argued that the prosecution failed to prove how she obtained or stored the poison.
All four men, including Mr Kakehi, were in their 70s.
She was engaged to Mr Suehiro, a former prefectural official from Kobe, in 2007.
