In the Advanced section of Modify Account settings for Yahoo!, there's an unmarked checkbox for Yahoo! Japan. What is this? As I am in Europe/Norway, is it something for me to think of? Do I need to open port 5050 and 80 as the following pager port and file transfer port says?

To aid in this question, here are all the settings as they appear on GaimPortable (2b5):

[Checkbox] Yahoo Japan

      Pager Server:   scs.msg.yahoo.co.jp
      Japan Pager Server: cs.yahoo.co.jp
      Pager Port: 5050
      File Transfer Server: filetransfer.msg.yahoo.com
      Japan File Transfer Server: filetransfer.msg.yahoo.co.jp
      File Transfer Port: 80
      Chat room locale: us

[Checkbox] Ignore conference and chatroom invitations
