BIANXBIAN NO LONGER EXISTS!
Even though I am not living in Japan anymore I like to make sure that this information is still up to date if I can. I recently tried to get onto the site and nothing is there 😦
Here is a website much like Mixi but only for women! You can create a profile just like Mixi and you don’t have to have a Japanese phone email (unlike Mixi >;( ). State your nickname, full name, location, summary, anything you’d like. This is also a great site for events. You can also join groups and meet people that way. This site is only in Japanese but some people might try to speak English to you. Have fun!
