Ketchup

Greetings!

Having a blast here in Japan and I was wondering how handshake events work?  I'm here until the 27th of July, so KFC will come out before I leave.  If I pick up a CD will there be enough time for me to go to a handshake event?  Or can I just buy a few handshake tickets at a ticket reseller and attend one before my trip ends?

If anybody could provide a link to a guide or a website on where, when, and who will be at the handshake event it would be greatly appreciated!
