Hmm... It's doing the same for me now when I try to access the page. I guess they changed something recently. My friend literally registered yesterday though so I'm not sure what is up with it. I will see if I can figure out a workaround.
OK! I have figured out how to do it. I have updated the guide now to reflect that : )
Basically, you have to download Firefox and set the browser language to Japanese. Please refer to the instructions above and let me know how it goes!
hdwei - I sent the registration email to your account to test ; )
