The Lower House on Thursday approved the Liberal Democratic Party-New Komeito ruling bloc government's nomination of Toshiro Muto as new Bank of Japan governor, resulting in a split decision after the opposition-controlled upper chamber rejected him just a day earlier.

Meanwhile, the possibility emerged that the ruling bloc may present someone other than Muto.

"Renominating (Muto) is an option, but there is the possibility of other options as well," Chief Cabinet Secretary Nobutaka Machimura told reporters Thursday morning.
