Tokyo - The mother of former Japanese prime minister Yukio Hatoyama, who was dubbed the Godmother of a powerful political and business clan, has died, her younger son's office said Tuesday. She was 90.
Yasuko Hatoyama, the daughter of the founder of tyremaker Bridgestone, married into the Hatoyamas, a powerful political family sometimes dubbed Japan's Kennedys.
She married former foreign minister Iichiro Hatoyama, whose father was a prime minister shortly after World War II.
Her sons both became parliamentarians, with the older, Yukio, becoming prime minister in 2009 as the leader of the centre-left Democratic Party of Japan.
He stepped down after less than nine months amid widespread complaints about his dithering and his weak leadership style.
Yasuko Hatoyama was for a long time seen as the real power in the family, which led to her being dubbed the Godmother, a play on the 1972 US mafia movie The Godfather.
She continued to be a controversial figure in Japanese politics, allegedly gifting hundreds of millions of yen to her sons in Bridgestone shares and in cash.
This was probed as a possible illegal political donation, but no charges were ever laid against her.
