Japanese Prime Minister, Shinzo Abe.

Japan's government approved on Saturday stimulus spending worth $29 billion aimed at helping the country's lagging regions and households with subsidies, merchandise vouchers and other steps, but analysts are skeptical about how much it can spur growth.

The package, worth 3.5 trillion yen ($29.12 billion) was unveiled two weeks after a massive election victory by Prime Minister Shinzo Abe's ruling coalition gave him a fresh mandate to push through his "Abenomics" stimulus policies. The government said it expects the stimulus plan to boost Japan's gross domestic product (GDP) by 0.7 percent.
