The Bank of Japan launched fresh easing measures Thursday after wrapping up a two-day policy meeting as it faced heavy pressure for more stimulus to spur the world's third-largest economy.

The BoJ's move to expand an asset-buying programme - its main policy tool - by 10 trillion yen to 101 trillion yen came days after Japan's conservatives won an election promising to boost spending and pressure the central bank for aggressive policy action.

The bank kept interest rates unchanged at between zero and 0.1 percent, but said it would look at reviewing its target inflation rate. - Sapa-AFP
