> My wife is South Korean so I'm biased. But I've been to Japan and South Korea and if you're looking for one of the most modern nations in the world, I strongly recommend you go to Korea. The only comparable country I've been to is the Netherlands or maybe Denmark.
Singapore is 728.6 km^2, while the Netherlands and South Korea are 41,865 km^2 and 100,363 km^2 respectively. The Netherlands and South Korea are much more comparable.
Have you been to Singapore?
