Well, wanna join the Speed Arena Net Fan Club and don't understand a word of Japanese? Well, you should be able to join by following my helpful guide on this page. ^_^
The extra box called Furigana is for folks with Japanese names. If you are using English, I guess that's everyone who is using this to join since you probably don't know Japanese, just type your name twice.
For the prefecture drop-down list, choose the very last option. It means outside of Japan.
For the Business / Work drop-down list, choose the very last option. It means other.
That should be it. Click the submit button and you should be on your way to joining the NFC. Please note, after you submit the form, you should get a screen that lists your Net Fan Club number. It is important that you write this down, because it is your ID. The number will start with 'nfc' and your member number will follow (e.g. 'nfc8994512').
Enjoy the club! ^_^;
