If your follow the twitters and blogs of the utaite you like then concert announcements will be difficult to miss. in addition, certain communities/blogs with as ofurotaimu and tumblr users who translate tweets and announcements such as Renna and Kirabeth I think orz I don't really keep track.

I also did a quick google search for this site I saw that compiled information and yeah it's called matome so it basically does what the title says and summarizes certain things and here is the one for utaite etc events in June so I hope that helps!
