Japan's parliament on Wednesday approved a $33 billion fourth extra budget to finance subsidies for disaster-struck businesses and the auto market, as the government looks to stimulate a faltering economy.

The upper house passed the extra budget of 2.53 trillion yen ($32.88 billion) for fiscal 2011 following its passage through the lower house.

The budget will provide funds to those affected by the March quake-tsunami disaster and the resulting Fukushima nuclear accident who are trying to service loans to restart businesses but who are saddled with repayments on now worthless or non-existent assets.

It will also finance market incentives for environmentally friendly cars.

Japan in November passed a 12.1 trillion-yen extra budget, following a four-trillion-yen package in May and another two trillion yen in July.
