Where to live in the following country's?

korea and japan are pretty much similar, but korea is more colourful and clean nowadays. plus, they have faster internet. japanese are much more nationalist. they have special terminology in the term for pure japanese and distinguish themselves from other races. They've been known to be one of the most racist during wartime. They even have places where they forbid foreigners from entering. However, they have well kept their culture. Koreans on the other hand, are much more open to foreigners but they may judge them on stereotypes since they are a country with mostly koreans. Like at the airport they let foreigners do stuff that koreans can't do. It's so slack to the koreans in my opinion though. they barely have much culture left, because the japanese destroyed most of it plus many buildings were demolished during industrialisation. Mongolia's not really good to live in.
