Japanese people all sound the same, and before you claim subtle racism find me two different Japs who cut a promo without sounding like the lyrics to Gangnam Style.
You simply can't be an all-rounder without mic skills, so Asians shouldn't really be on this list at all IMO.
Two points to make on your post.
1. Most Japanise wrestlers who work in Japan would speak in their native touge, so maybe the people over there are in a better position to comment on their promo skills, also charasma is charasma, just because you think their voices all sound the same doesn't mean they don't have charasma.
2. For the 150th time this list was based on in ring performances, stop talking about promos.
Hometown Kid thank-you for your well thought out response and the insight you provided clearly you are in a better position to judge than man, however I do feel that maybe you went a bit far to suggest that no american talent deserve to be on the list. Surely you would concede that the likes of Punk, Bryan, Aries, Roode, Styles etc are outstanding?
