Liberal Democratic Party member Taro Kono said Thursday he has submitted a proposal to an LDP panel he heads calling for the Nationality Law to be revised to allow offspring of mixed couples, one of whom being Japanese, to have more than one nationality.
The panel will scrutinize the proposal, but there is no time limit to formalize it as "this is not something that needs to be done anytime soon," he said.
Under the current system, Japan, in principle, requires Japanese nationals who also hold citizenship in another country to choose one or the other before they turn 22.
