Japan’s scandal-embroiled agriculture minister stepped down today to take responsibility for a shattering election defeat for the ruling party.

“There is no doubt about the cause of the ruling party’s election loss. I feel very sorry, and I have decided to step down,” Agriculture Minister Norihiko Akagi said on nationally televised news.

Akagi had been hit by an embarrassing accounting scandal widely viewed as one reason the ruling Liberal Democrats suffered a devastating defeat in Sunday’s election.

The Democrats won in a landslide, emerging as the top party in the upper house of parliament for the first time.

Criticism had been growing against Prime Minister Shinzo Abe’s administration.

Akagi is suspected of reporting $730,000 in office expenses over the past decade for a political office that was registered at his parents’ address and was defunct.

Akagi took office in June, replacing his predecessor, who committed suicide following money and bribery scandals.
