I'm not quite sure about the naming of this product/franchise.
VIZ Media prints it as InuYasha everywhere, however they always reference it as Inuyasha on the site.
Same thing for the movies, the logo reads for example "InuYasha The Movie 2: The Castle Beyond the Looking Glass".
I guess the correct one is InuYasha since it's what's printed on every dvd/manga ever released, but I wanted to ask before changing them.
