Neymar and Oscar stuck either side of halftime to give Luiz Felipe Scolari's side a comfortable victory in front of a record crowd at the World Cup Stadium.
Brazil chalked up its third victory in a row as goals from Neymar and Oscar guided the team to a 2-0 friendly victory over South Korea.
After a first period devoid of clear-cut chances, Neymar lit up the game with a sublime free kick on the stroke of halftime.
The encounter was put beyond doubt shortly after the break as Oscar rounded goalkeeper Jung Sung-Ryong and fired into the open net.
Coach Luiz Felipe Scolari named an attacking starting XI with Neymar and Hulk partnering Jo in a front three.
South Korea boss Hong Myung-Bo left Bayer Leverkusen forward Son Heung-Min on the bench, although Sunderland midfielder Ki Sung-Yeung earned a start.
The Selecao's first glimpse of the Korean goal came when Hulk played a one-two with Jo before shooting, but his strike was smothered by Jung.
Chelsea midfielder Oscar then hit a snap shot on the turn from 25-yards that cleared the crossbar.
The home side tried to take the game to Brazil before halftime, with David Luiz crucially heading an fine Lee Chung-Yong cross away from Koo, before a surging run from Kim Bo-Kyung resulted in the midfielder firing straight at Jefferson.
The home team failed to make the period count and Brazil went ahead on the 44th minute.
Neymar was felled by Lee Yong on the right, allowing the Barcelona star to curl a superb 25-yard free kick into the corner on the stroke of halftime.
Scolari’s men doubled the lead four minutes after the interval.
Oscar collected a defense-splitting pass from Paulinho and deftly beat the goalkeeper before passing into an empty net.
Brazil then went close to extending the lead on the hour mark. Neymar's cross caused panic in the South Korea box and Luiz Gustavo made a late run to power a header goalwards only for Lee Yong to make a crucial deflection.
South Korea nearly reduced the arrears from a corner with 20 minutes remaining, but Lee Chung-Yong put his near-post header wide.
Substitue Hernanes could have added a third in the dying stages, but the Lazio midfielder's effort went straight at Jung from the edge of the box.
This made no difference to the result though, as Brazil built on victories over Australia and Portugal in its last two fixtures.
Scolari's men will now switch their focus to Tuesday's friendly with Zambia in Beijing.
