Dear people who know languages besides English

I hardly EVER visit non-English sites, but the ones I do visit that are Japanese would be :

http://maplestory.nexon.co.jp
http://maplesonar.com/wiki/
http://hangame.co.jp
http://mixi.jp
http://nicovideo.jp


Other English websites have Japanese people I can talk to in their own tongue, so I don't have to stray too far to find people to converse with.
