Doraemon still seems to be airing in Japan as well. I bet he still has those 9 lives after that long.

@sickVisionz: Didn't the Bleach anime end months ago?

Detective Conan/Cased Closed is still going (episode 660 is the newest), so there's another one.

Oh, what about the second Gintama anime, it ran from April 2011 to March '12.

I'm not sure if either of these count but the Pretty Cure franchise is still going strong with a new edition each year. They're up to season 9 now I believe with Smile PreCure.

My second suggestion would by the soccer series Inazuma Eleven. There are three series within the franchise but, unlike PreCure, the same characters appear in each series albeit at different stages in their lives. It's a little like Major in that way or Naruto come to think of it. The current series is Inazuma Eleven Go 2 Chrono Stone and it's still airing.

If you're looking for shows which have kept just the one original name throughout their run and are still on-going, then I can't think to add any others to what's been stated above.

EDIT: Would Phi-brain Puzzle of God count? It started in October of 2011 and is currently still airing although that's season two, which has the same title as season one but with a "2" tagged to the end. I'm not sure if that's enough to disqualify it or not.

@sickVisionz: Upon further consideration, you'll probably want to drop Inazuma Eleven GO 2 Chrono Stone down to "Spring". The installments within the franchise have always run back-to-back, but they do take on a new numbering with each new series. For clarification, the original series ran for 127 episodes. After it ended, the following week, Inazume Eleven GO began and that ran for 47, and like its predecessor, with its conclusion, GO 2 Chrono Stone began and is up to episode 7 or 8 now. Since each series has its own numerical arc, for bookkeeping purposes, they should probably be counted as separate.

EDIT: Would something like Gundam Unicorn count? It's not long running since it's only up to episode 5 of a planned 7, but it started back in 2010 and episode 5 dropped just last month. It's an OVA series too as opposed to TV broadcast so that might disqualify it as well.

@sickVisionz: You know after all my focus on Inazume Eleven Go 2 Chono Stone, I never though to suggest Inazuma Eleven Go. It began in May of 2011 and ended in April of 2012. In 2012, there were 13 episodes that aired leading to its concluding 47th show. source

I've spent a lot of time thinking about this franchise over the last day or so. Yeesh! ;-)
