Since we have some people here who don't have jailbroken devices and are unwilling to jailbreak their devices, I think I will start a request form for people to PM me info in order to get your account authenticated. If you don't live in Japan or don't have a location spoofer due to no jailbroken device, pay attention.
This blog explains how to make a Japanese iTunes account without an iTunes prepaid card or Japanese credit card.
1. Go to
this page and click the blue signup button on the top right of the page.
2. Go to the bottom of the TOS page and click the button on the left.
3. On the next page, enter your email address and submit (it can be any email address you like, doesn't have to be the ones you use with iTunes).
4. Check your email for the message from the Bana-pass website, click the long URL, and fill out the page accordingly:

5. Click the confirm button on the right
6.. PM the following to me:
a. Email address
b. Password (I would really appreciate if you make a short password for your iM@S Mobile i account since long passwords are a pain to type in on an Apple device)
c. Producer name -
8 CHARACTERS OR LESS (Give me something unique that might not have been taken by someone else, and give me a few alternatives just in case.)
d. Preferred idol (Idols can only be changed on the 5th, 6th, and 7th days of the month, so make sure you're content with your decision. Also Ritsuko and Ryuuguu Komachi idols are included in this, so choose whoever you want)
Leave the rest to me and I'll PM you with any important information regarding your account when I create it.
Please keep in mind:
You will be exposing your email address to me if you request that I authenticate an account for you. You can trust me though, I wouldn't do anything horrible.
