title: How to make certain JIRA issues only visible by a group of people?
body: <p>My company is trying JIRA and we were wondering if there is a way to make issues visible only by a certain group of people. For example if the issue was open in Germany it should only be visible by German users, if it was open in Japan only by Japanese users. The only exceptions are admin and devs that would be able to see globally.
  In redmine this is fairly easy achieved with the sub-project feature, but how to do the same with JIRA?</p>
  
  <p>PS: I would like it to be automatic and not based on a field the user has to chose. </p>
