Prime Minister Naoto Kan's decision to bring former Finance Minister Kaoru Yosano into his Cabinet signals a return to fiscal reforms that helped send benchmark bond yields to a seven-year low last August.

The appointment of Yosano, who advocates increasing the 5 percent sales tax, follows government and central bank stimulus efforts that pushed yields to the highest since May last month.
