I think it could be a success, but the audience in Japan was pre-built based on the successful anime/manga series. I don't think they have any serious exposure in the USA afaik.
Pokemon for example started in the USA with the gameboy game AND anime starting in September 1998.
For YW it's apparently Disney XD, which is a pretty weak place to try to get major exposure going :
