As many PS3 users know, Japan gets many demos that others don't get, as well as sometimes games.  Only problem is that they are probably going to be Japanese.  If you are like me and know there is a demo you want to play anyways, regardless of the language (and it may save you from some spoilers), then you should make a Japanese account.  After I heard the Devil May Cry 4 demo is coming out this Thursday, but only in Japan, I finally made myself an account in Japan.
Some of you are probably like me and need help reading Japanese.  Here is a great site I found that helped me make my Japan account.

The response has been enormous. I thank you all for watching. However, it seems the table has turned in the last couple of weeks. Sony smartened up and now they are validating the street address as a part of the account setup. Since I had a bit of free time at hand, I decided to visit this one more time and help you out.

So. Previously, I stated in the video that in the address entry page you can fill in “123″ into all fields and it would work. This is not true anymore. The simple fix would be to just to provide with you a random address in Japan, but that may lead to Sony blocking specific addresses, so I decided to pull a little prank this time. Why not enter SCE’s own HQ address!? Brilliant. They wouldn’t dare to block their own HQ street address. A quick visit to SCE’s website revealed this page.

So their address is this:
ZIP: 107-0062
Prefecture: Tokyo (東京都）
County/City: 港区南青山
Street Address: 2-6-21

Which then looks like following on the screen:


you must be scared of those Kanji characters. Don’t worry. I’ll explain entering them in the step-by-step guide below.

Requirements:
1. I assume you’ve stepped through the previous pages and you are on the address entry page.
2. You want a keyboard. A lot of USB keyboards should just work plug-n-play style, so give it a shot. If not, then follow the steps below by using the on-screen keyboard.

HOWTO:
1. Activate entry for the zip code.
2. Enter this:
“107-0062″ (without double quotes, of course)
3. Activate entry for the country popup menu.
4. Scroll through until you find this one: 東京都
5. Activate the next text field, which is the county/city field.
6. On your keyboard, type the following alphabet phrase in:
“minatokuminamiaoyama”
7. If you typed it in correctly, you should see this:
“みなとくみなみあおやま”
8. Now hit space bar. You should see the characters converted into this:
“港区南青山”
9. Now, hit enter on your keyboard or hit Start button to get out of the Kanji conversion mode. Hit enter/Start button one more time to get out of the entry page.
10. Activate the next input field for the street address.
11. Enter this:
“2-6-21″
12. Hit Enter/Start Button to get out of the entry mode.
13. You are done. Follow rest of my YouTube video. I verified today that there is no more blocking issues afterwards.

Don't worry about the “みなとくみなみあおやま” stuff. If it doesn't do that, it is still okay, since mine just kept it as  “minatokuminamiaoyama” and everything worked out perfectly.  Make sure you combine both the instructions with the video, since Sony changed how you do it.

sweet, will be useful if i get a PS3

It sounds like DMC 4 demo may be confirmed for NA too, and at least on the 360.

Regardless, I am glad I got this outta the way in case I ever need it.
