Step 1: Go back to
http://pso2.jp/ Step 2: Ok, time to create a SEGA ID account so you can log in to the game after the download is complete. Click the big yellow SEGA ID Button on the left side of the screen.

Step 3: A new window should open. In the blank box in the center, enter your email address.

Step 4: Close that window and go to your email inbox. Click the link in the middle of the mail you just received from SEGA.

Step 5: Fill out this page as shown in the picture and click the Next button (the button at the bottom).
[*Note: If you encounter a Japanese captcha box but don't have Japanese installed for your keyboard, you can copy and paste the Japanese letters from Wikipedia one by one to spell it out.]
Step 6: On the next page, check to see that your info is correct and then click the Next button at the bottom of the page (it's the top one of the two). If you made a mistake, click the other button.

Step 7: Congratulations, you now have a SEGA ID account, but don't close this window yet. First we have to give your new account permission to play Phantasy Star Online 2; so click that button near the bottom of the page.

Step 8: This new list is a page of all the games that use the SEGA ID service. Phantasy Star Online 2 is written in Japanese, but you'll find it right below MJ.NET for PC. Click the gray button under the PSO2 link to activate it on your account.

Step 9: "Read" the licensing agreement and click the left button.
Step 10: All right. Your SEGA ID account is made and you're authorized to play PSO2.
