Muta succeeded more or less in the U.S. (and the Great Kabuki before him). So, it can be done with a Japanese wrestler who may not even have a strong command of English. But I don't think WWE has ever had a good case of it. Shinzaki, the Great Sasuke, and Ultimo Dragon were all reasonably big elsewhere. But more or less floundered in the mid-card in WWE. I think Shinzaki was in a jobber stable at one point, with Barry Horowitz and some others.
