Day two of the first lay judge trial saw another historic first when one of the six citizens on the bench posed questions to a murder victim's son as he took the stand at the Tokyo District Court.

This marked the first active citizen participation in criminal trial proceedings.

The trial of Katsuyoshi Fujii, 72, started Monday when he pleaded guilty to fatally stabbing his neighbor, Mun Chun Ja, 66, in May.
