Among other goals it failed to achieve while in power, the Democratic Party of Japan will call for cutting 80 of the 480 seats in the Lower House in its campaign pledges for the upcoming Upper House election, a draft of its platform shows.

The party vows in the draft manifesto to restore the country's fiscal health through revenue and spending reforms and an economic growth strategy.

The DPJ, which was defeated by the Liberal Democratic Party in last December's Lower House election, is critical of the economic policies of Prime Minister Shinzo Abe's government, dubbed "Abenomics."
