Dunga's men were 2-0 winners over Argentina in Beijing on Saturday, Diego Tardelli scoring a brace for the World Cup semi-finalists.
The World Cup hosts have not conceded in three matches since shipping 10 goals in their final two matches of the showpiece tournament.
"I want to use all the possible replacements, which are six, especially because the players had to go through a very long journey to China and pollution conditions were very bad," the 50-year-old said.
"So they are very tired because of that, so I really intend to use all the replacements which are possible to be used in this match.
"I will first talk to the players to see the level of their tiredness, if they are ready then I'm not going to change it.
"We have now five new players in the line-up and they have played together for the fourth match.
"In my vision there is no point to be changing all the time, to be replacing players because I need to allow them to create a certain trust, to create a certain confidence so that they can play as a team."
"I played against Japan many years ago but I cannot compare them to nowadays because at that time Japan had no experience in terms of international matches and today the Japanese team has improved a lot," he said.
"So it's a totally different situation where they have very good players that are playing in other leagues around the world."
