Which languages are easy to learn?japanese,french,italian?

English is the only language you need - everyone speaks it. Unless you want to go and live in another country - in which case learn that language. Oz ppl used to go and teach english in Japan when it was the world's number 2 economy during the 80s but now the Japanese economy is down. In your region of the world China and India will be the leading Economies in the next decade or so - but Chinese only do business with their own and India speaks English as the common language. I've been to Spain and France many times and they all wanted to practice their English with me unless you are going to French speaking countries in Africa or Spanish speaking countries in America don't bother with those. So decide where you want to specialise your tourism in and then learn that language!
