Mmm I've learnt Japanese before (though it's so rusty now, my talent could fall apart if I tried to use it) and I really enjoy the language but being honest the language I'm currently interested in learning and which seems hard as smurf for me to get my pronunciation right in is Norwegian. My reasons for learning this language is because having visited the country, I'd love to go back more and more. Although many are fluent in English, it'd be nice to go there and understand all the things I see and hear and people I meet without having to inconvenience them by asking "Sorry, could you please repeat that in English?" to them.
