Yosano's comments Tuesday as well as other recent ones indicate he thinks prices are on solid ground and that it's okay for the central bank to make a rate move soon. He also brushed aside the view that the government and the BOJ ought to use a "core-core" CPI. As part of their debate over prices and the proper course for monetary policy, internal affairs minister Heizo Takenaka continues to disagree with Yosano. Friday, Takenaka, noting the only 0.2% increase in the April CPI excluding energy and fresh food, reiterated that slight prices declines continue and that using the "core-core" was the best way to evaluate price trends.
