Former finance minister Shoichi Nakagawa has been found dead at his home in
Tokyo, it has been reported.
Nakagawa, who was 56, was found at his house in Setagaya, with local reports suggesting that he was found next to packets of sleeping pills and that he had been unhappy over recent months.
His father Ichiro Nakagawa, a former agricultural minister, committed suicide in 1983, aged 57.
However, police have said that in this case, suicide is "unlikely".
The former minster hit the headlines earlier this year when he appeared to be drunk during a G7 press conference.
After the incident, he resigned.
Leading the tributes, former Japanese prime minister Taro Aso praised Nakagawa for helping to deal with the recession in the country, which was the deepest since the Second World War.
"I'm in such a state of shock right now that I cannot put it into words. I offer my deepest condolences," he said.
