Brazil beat Alberto Zaccheroni’s Japan 3-0 in the Confederations Cup opener, as Italy face Mexico on Sunday.
The hosts opened the tournament in Brasilia with traditional style, as it took just three minutes to break the deadlock.
Fred chested down a ball for Neymar to strike sweetly on the half-volley from the D, giving the Seleçao the lead.
They added a second straight after the restart with Inter and Roma transfer target Paulinho. The Corinthians midfielder gathered a Dani Alves cross from the right and turned to fire in from 16 yards.
Substitute Jo, who was only called up after Leandro Damiao pulled out with an injury, scored his first senior Brazil goal in stoppages.
He sprung the offside trap from a wonderful Oscar through ball and nutmegged the on-rushing goalkeeper.
