A 25-year-old Japanese model has been arrested on suspicion of poisoning her real estate mogul husband just months into their marriage.
Kosuke Nozaki described himself as a Japanese 'Don Juan' and claimed in his autobiography he had spent US$27.5 million on wooing 4000 women in his lifetime.
The real estate mogul died in 2018 at age 77 of acute poisoning after his wife, Saki Sudo, allegedly gave him a significant amount of an unspecified stimulant.
Some reports allege it was mixed into a drink and consumed as no needle punctures were discovered on his body.
It is alleged Sudo had been researching information about drugs online before her husband's death, the Japan Times reported.
In his will, Nozaki stated he wanted to donate nearly US$12 million to the city of Tanabe, where he lived.
But because half of his estate goes to his widow under civil law, the city had been in talks with Sudo about dividing the money, the Sankei Shimbun reported.
Nozaki, who ran a real estate company, liquor sales business and money lending enterprise, claimed in his 2016 autobiography "the reason I make money is to date attractive women".
In a Japanese business column in 2018, it was stated Nozaki was "confident of becoming happy" by marrying Sudo, even after people warned him she was just after his fortune.
Nozaki became famous in Japan after a 27-year-old woman he dated stole over US$500,000 worth of cash and goods from him in 2016.
It is believed Nozaki and Sudo met after he tripped over to get the model's attention at an airport in Tokyo.
