Some instructions that I posted awhile back about using the Japanese client are here:
I made a tygem account through the Japanese website with no problems. You just follow the instructions that they have on the site, and things go fine.
Here are some steps.
1.) Go to tygem.co.jp, and click on the ログイン button (the top left button in the image below). Alternatively, you can click the link under "Step 1".
2.) On the next screen, click on the "無料会員登録" button (it is the top yellow button with the weird white character shown below the login dialog).
3.) You will see a big user agreement form. Just scroll to the end, and click on "WEBで申し込む" (shown at the bottom of the second of the next to images. There is a computer icon near the button.).
4.) Fill out the user information on the next page. In order, the items you need to fill out are:
Japanese Handlename, Foreign Handlename, Name, Password, Password Confirmation, Date of Birth, Email address, Email address confirmation, Go Strength, Number confirmation (just enter the numbers that are shown), and avatar.
5.) Click on the left of the two buttons at the bottom of the form.
6.) After this, you may get an email with information, and you should be able to log into the system. You can log in from the website, using your username and password.
That's all there is to it, really. I typically use the Korean client these days, so please feel free to post updates to the process of using the other clients in this thread.
