Jpop concerts in July

Hello,

As we're gonna be in Japan in July, would like to know if there is a site with JPOP artists concerts information. It would be a very good experience to be locally in a show like that.

Thanks,

http://www.tokyogigguide.com is the only one I know of in English and that only covers Tokyo. But you could keep your eye on places like JaME for gig announcements for major bands, or find venues near where you plan to visit and check their websites. Some venues are part of chains, like ZEPP, and their sites are fairly easy to navigate with Google Translate. Buying the tickets is the tricky bit, I think :)
