Forgive the post in English but this seems to be the place to post for this!
はじめまして。ジョンです。よろしくおねがいします。ぼくは日本のメルともを見ます。
I am not sure if I wrote that properly, but I am looking for a Japanese pen pal or email pal. I'd love to practice my Japanese and help you with whatever questions you may have about America! It'd be awesome if I could find someone around my own age (35) too. That way we might have some things in common, like music, books, or hobbies! But even if you are older I wouldn't mind, in fact that might be a really cool perspective.
I know asking for a pen pal is old school, but I had a Japanese pen pal in high school (that I lost touch with) and we had a blast! It was so exciting to get that airmail envelope!
Though, finding a friend on Skype to talk to and practice speaking with would be cool too in a pinch, but my schedule can be pretty odd. I'm a home health aid so it is hard for me to have a set time since I can be working at 1PM one day or 3AM another! Hence another reason for the old fashion method.
