Natsume has confirmed that River City: Tokyo Rumble will launch on the 3DS in North America on September 27th.

Developed by Arc System Works, the game will be released in physical and digital formats, and those who order a copy from Natsume's new Amazon store will receive a limited edition Kunio keychain.

Here's a little snippet of the official PR:

River City: Tokyo Rumble follows the story of a hot-blooded high school student named Kunio and his good friends. When a nefarious gang moves into Tokyo to try to take it over, it's up to this self-proclaimed "fighter for justice" and his buddies to make sure the streets stay safe! Players will punch, kick, and use a variety of weapons such as soccer balls, iron knuckles, chains, and even bicycles to knock some sense into those devious gang members. Taking on jobs, leveling up abilities, and stopping for a snack or two at local food joints are just some of the action-packed mayhem players will experience. Luckily, smiles are free!

And this is what the keychain looks like:
