Hi everyone,
I saw this topic and I couldn't stop myself althought I think is quite old, but anyway... I have to tell you that unfortunately, the Japanese Fanclub is ONLY for Japanese people or for people who are living in Japan. To join them, you have to send a letter to Dears giving them you details and then, they send you a letter with a postal pay card. You have to pay it, and then wait. It ussually takes 3 months to see your Dears ID Card...
For foreigners there is a Fanclub called World Dears, in which you can enter without paying. If you write World Dears in Google I'm sure you will see the address.
^^
Hope this information help someone in the future.
If you want any more information, please, contact me ^^
