Uninspiring Rikishi's Koenkai

Hey guys,

It has been a few times watching bouts of really uninspiring rikishis that I wondered if they had a strong fanbase in japan and if their koenkais are thriving or really just small. I think for instance—and I have nothing against them—to Tohakuryu or Mitoryu (amongst others). Do they have a really dedicated, albeit small, koenkai? If so, what are the motives of the individual in those koenkai?

I am not trying to be negative; I am just interested in the lives of those "average" rikishis and the organisation of their support.

Thanks for the insights!
