The Diet has enacted a ¥3.12 trillion extra budget for fiscal 2014 to fund an economic stimulus package aimed at boosting domestic demand aggravated by last year's consumption tax hike and the yen's plunge.

The supplemental budget was approved Tuesday evening in the Upper House with a majority vote led by Prime Minister Shinzo Abe's Liberal Democratic Party and junior coalition partner Komeito.

It allocates ¥1.19 trillion for subsidies to alleviate the negative impact of higher prices and allow municipalities to implement measures to shore up their economies at their own discretion.
