I wouldn't really compare South Korea and Japan with Qatar, because Korea and Japan have a much longer football tradition, they have invested much more in football, and they have a much larger population and a much larger football base.
Just look at their results in the last world cups, Korea and Japan often make it to the knockout stages of world cups and achieving great results.
Ok, it seems that Qatar is currently achieving good results in friendly matches, but does anyone seriously think that they would have qualified for this World Cup if they did not have the direct right to participate as hosts?
No, of course. No one holding that illusion. Before, Qatar isn't on the same level as some of the MENA teams in the region. If not for the host right, they wouldn't even pass against other strong teams like Iran, Iraq and Saudi Arabia. Qatar recently got good only because of the massive preparation for this World Cup. They got a lot of new players under their national team, buying and transferring left and right just for the stake to put up a good face as a host. I'm damn sure after this World Cup is over, Qatar will fall back to its place, behind stronger teams in MENA. Money can only buy them some temporary victories before and a bit after this World Cup.
I will also jump the bandwagon of people saying NO, and if I could swap them for another team then I would have gladly use it to bring back Italy. Furthermore do you’ll think that it’ll be a nice opportunity to make some quick bucks while wagering against them, and even though I’m expecting super low odds I yet feel that we can earn some good bucks on their matches if we get lucky.
