Onecheebara.
It's out for the Xbox 360 now, if you'd like to pick up a higher-def version of the game.
It's been under a few different pronunciations. Onechebarra, Onechanbara, ect.
It's made by D3 under the budget price series. It was fairly big on the PS2, since it was a sub-5k yen pricing.
Made by the same developers that have given us "Simple 2000 series: Zombie vs. Ambulance" and "Earth Defense Force 2017".
However, with next-gen costs being so high for PS3/X360 titles, they've decided the only way to do it was go with the Wii for next-gen. This is their first Wii title. Hopefully it does well, so we can keep getting budget titles from D3.
Edit - Here's a wikipedia lookup on the series:

Back from the dead, I'm afraid.
