According to Yomiuri, the Japanese government will commence work on the budget in November, with the budget expected to last till the end of the fiscal year in March 2012.
The budget will also include funding for rebuilding following a recent storm that hit western Japan, and will be funded with the surplus cash that was set aside for bond interest payments, which turned out to be lower than expected.
The news came a day after Japanese Prime Minister Yoshihiko Noda gave his first major policy speech to the House of Representatives in Tokyo, where he vowed to devise a plan to reinvigorate the nation's sluggish economy and enhance restoration efforts in the wake of the March disasters.
Noda added that he hoped both Democratic Party of Japan (DPJ) and Liberal Democratic Party (LDP) politicians could put aside their differences so that the necessary bills for reconstruction funds, social security and tax could be swiftly passed through a divided parliament.
The Japanese government is currently working on a third extra budget, expected to be worth more than ¥10 trillion, that it aims to submit to parliament by October.
