Japan executed a Chinese man after he was convicted of the murder of a family of 4, in his first death sentence to be carried out by a foreigner since the details of the sentences carried out in 2007 were revealed.
Media reported that the Chinese, Wei Wei, 40, committed the crime in mid-2003 with two other partners, who are also from China.
The two partners fled to China and were arrested there, according to Reuters.
One was executed in China in 2005, and the other was sentenced to life imprisonment.
Japan is one of only two countries in the Group of Seven that maintains the death penalty, along with the United States.
Before 2007, the identity of those who carried out the death penalty was not revealed.
