Al-Hilal won 1-0 thanks to an own goal by Al-Ittihad captain Ahmed Hegazy in extra time on Sunday to reach the cup final where they will face Cristiano Ronaldo's Al-Nassr or lowly Al-Wehda.
It was the second consecutive win for Al-Hilal, who are in fourth place in the league standings, seven points behind leaders Al-Ittihad who have two games in hand.
"We have five days until the final (against Urawa), and we can recover on the physical and mental levels. We turned this page and (now we) think about the next (game)," Al-Hilal goalkeeper Abdullah Al-Mayouf told local SSC TV.
Al-Hilal, who lost 5-3 to Real Madrid in the Club World Cup in February, host Urawa in the first leg on April 29.
The second leg will be away at Saitama Stadium on May 6.
Despite Al Hilal's position in the league, they will play in the Asian Champions League next season as last year's Saudi champions, due to changes in the Asian championship's start and end dates.
