Viz is the only
official licenced translator in the US and Canada.
There are others floating around on the Internet and they only translate the most recent chapters that are published. The two most popular ones use the same translation, so the main difference is scan quality and resolution.
AdInuyasha and
Freelance Manga There's also one from china, but they just started publishing it in english forr the first time this week. The translation isn't the same quality as the first two I mentioned, but they're faster.
