Noda is expected to be confirmed in parliament Tuesday as the nation's sixth new premier in five years, replacing outgoing Naoto Kan who quit last Friday after his approval rating tumbled over his handling of the triple crisis.

Known as a fiscal hawk and a safe pair of hands rather than a charismatic leader, 54-year-old Noda has pledged a "middle-of-the-road" politics.

Speaking immediately after being elected president of the ruling Democratic Party of Japan (DPJ), Noda bowed deeply several times then pledged: "Gritting our teeth, let's create a stable, reliable and mature politics."

He promised to push for a speedy recovery from the March 11 disaster and its economic impact, and vowed to unite the deeply divided ruling party so that "everyone works together for the sake of the people."
