Ruling coalition lawmakers have called for an extra budget that would include ¥10 trillion ($92 billion) in spending to support slowing growth and recovery from two powerful typhoons, party officials said on Thursday, raising worries about straining public finances.

The agreement, made in a meeting between senior officials of the Liberal Democratic Party and Komeito on Wednesday, highlights the concern among lawmakers about the economic outlook due to a sales tax hike in October and slowing global demand.

"Prime Minister (Shinzo) Abe told us to compile a sizable package to take all possible steps on the economy," economy minister Yasutoshi Nishimura told a news conference on Wednesday.
