Later that day they face Australia before their final match of the pool stages against China. The finals take place the following day.
The teams have entered the closing stages as regards their preparations for the tournament with Australia's women gearing up to defend the title they won in Dubai four years ago.
Part of that preparation is the HSBC Sevens World Series and the IRB Women's Sevens World Series which are currently ongoing.
Ireland are in Hong Kong this weekend for one of the highlights of the season while they are also looking forward to the China round of the Women's series, which takes place between March 30 and 31 in Guangzhou.
And as the excitement mounts among the teams, the buzz is also building among the ever-growing number of Sevens fans around the world as tickets are now on sale for the biggest Sevens event of the year in what is a new frontier for the world game.
Rugby World Cup Limited Chairman Bernard Lapasset said: "The teams know that these 100 days will fly by very quickly and so they are all busy making their final preparations for the tournament.
"Judging by the schedule, we are in for a treat of world class Sevens on each of the three days of competition.
"The way the game is continuing to develop, I expect this Rugby World Cup Sevens to be the highest quality yet with skill, speed and fitness levels like never before, in both the men's and women's sections."
