Meet locals online

I just visited Tokyo with a few friends and had a blast. I'm already considering planning another trip but I might be going alone. So I was wondering if there is any way to meet Japanese people online without that shady mail order bride feeling. On our last night we met with a local Japanese friend and had a lot more fun in just one night. That's where this idea came from.

Yes, you can become serious friends with people you find on-line, which I hope what your question is. The trick is to have something serious in common, such as language studying, educational issues, love for certain art or sport etc. Hope you have fun!
