Searching friends in korea and japan to learn the language

Hello! I'm Soso from France living in the lovely city of Paris. I am 26 years old and am actually studying. I have a holiday of 3 months this summer so I am planning to visit Korea, Japan and Thailand with some friends. That is why I would like to find a person (preferably a girl) living there who could perhaps teach me a little bit about the culture there and the fun places to go. It would be very nice if she knows a bit of japanese also, would love to visit Paris so I can also be useful by teaching her french language and show her around someday. Thanks everyone!
