Japan is undergoing the greatest budgetary reform process since the end of World War II with authorities trying to reduce the nation’s reliance on extra budgets to meet any unexpected spending needs, Finance Minister Satsuki Katayama said.

“As for budget system reform, this is clearly the biggest overhaul since the end of the war,” Katayama said at a news conference Tuesday. “That’s the level of commitment we’re bringing to it.”

Scrapping extra budgets would be a major change to Japan’s budgetary process given its annual reliance on them. Still, it remains unclear if the move would constitute postwar Japan’s largest budget reform.
