"First we have to finish in the top three at (next year's) Asian Cup," the 57-year-old Italian told reporters after being unveiled as Japan's sixth foreign manager.
"When my Japan adventure comes to an end I want the fans to have great memories of Zaccheroni's samurai."
"You can call me Zac," said Zaccheroni. "But I am OK with any nicknames the Japanese fans have for me."
"I expect him to get the Blue Samurai to the last eight in 2014," Ogura said in a statement. "He has vast experience and is a real tactician of the game. I expect him to get Japan to play an attacking style of soccer."
The JFA did not reveal details of Zaccheroni's contract but it is understood he has signed a two-year deal with an option for another two years.
Zaccheroni, who led AC Milan to the Serie A title in 1999, said: "I jumped at the opportunity when the JFA came with their offer."
"Okada-san did a fantastic job," said Zaccheroni. "He left a great foundation in place."
Zaccheroni will watch Saturday's home friendly against Paraguay in Yokohama from the stands as he is still waiting for a work permit.
"Coaching a national team was the only challenge left for me," said Zaccheroni, whose first game in charge is expected to be the Oct. 8 friendly with Argentina in Saitama.
"Now I have the opportunity."
JFA technical director Hiromi Hara said Zaccheroni's lack of experience outside of Japan would not be a factor.
"His motivation and passion will make up for that," said Hara. "It's a life's ambition for him to coach a national team."
