Spanish is the way to go.
Well, maybe in the US but considering our tourism and trade focus in Australia and the make up of our population, Japanese would be by far the more practical.
Spanish is the way to go.
Actually, this is still a matter of some controversy. Linguists are evenly split between considering Korean a language isolate or rather part of an "Altaic" language family with Central Asian origin.

Yet, in my own pursuits, I'm finding some commonality with Hungarian. I have no background in Mongolian but considering that the two languages meet in places suggests that there was more than just coincidence. After all, Hungarian also draws some Persian into it, which might overshadow anything else.
Hungarian is an absolute cow to learn trust me I know. My folks are Hungarian so I hear it a lot at home. I don't speak much but understand most of it
I'd say Chinese. It's not easy to learn but it's quite rewarding to be able to speak properly.
And you'll be able to speak to another billion people. Just make sure you learn simplified characters because traditional is a real pain. And do they teach Mandarin or Cantonese?
Not to hijack, but anyone feel that Arabic is worth learning?
