There is 2 Nyotengu players+along with the one FoN posted. A really popular Nyotengu player is someone by the name of OYU, however most of the JPN players normally get their videos uploaded on NicoNico instead of sites like Youtube. Why? I have no idea, I think NicoNico sucks (seriously, who pays for HD and having it archived?)
What's also difficult about the Japan players is that their social community is by Twitter majorly (most of their best players don't even use JPN FSD either) and they hardly upload videos except maybe on NicoNico. That site is already a mess with trying to translate it and trying to get the results you want on the site with what you are trying to look for.
Actually from what I hear, Terurock and Siologica believes that OYU is best Nyotengu over there despite him playing a sub character (Phase 4) more often. Unsure if he plays Phase 4 due to feeling Nyotengu might not work out on this match up, or opponent having better luck in match situations against his Nyotengu. Wish I knew the answer for that one.
