Brazil opened the 2013 Confederations Cup in style on Saturday, defeating Japan, 3-0, at the Estadio Nacional Mane Garrincha.
The Brazilians scored three minutes into both halves as Neymar started it off with a sensational strike in the third minute before Paulinho extended the lead in the 48th minute. Jo completed the dominant display by tacking on a third in second-half stoppage time.
The result brings Brazil to the top of Group A as Japan falls to the bottom of the group ahead of Mexico's meeting with Italy on Sunday.
The opening goal came by way of a stunning strike from Neymar. Marcelo's diagonal ball to the top of the penalty was chested down by Fred, allowing the newly-unveiled Barcelona attacker to fire a first-time laser into the upper corner.
Brazil's lead was doubled early in the second half when a cross into the box was collected by Paulinho. The Corinthians midfielder took one touch to settle before lashing a shot on goal that Japanese goalkeeper Eiji Kawashima got a hand to but failed to keep out.
Jo, who entered the match as a substitute in the second half, put the icing on the cake in stoppage time when he latched on to Oscar's perfectly-weighted through ball and slipped a shot into the back of the net.
