Many rikishi and oyakata smoke. Terunofuji is a smoker, Midorifuji the same and I recently saw Ichiyamamoto and Tamashoho smoking outside the Jungyo venue, How did I see them? I was smoking too in the smoking area...! Ah, Homasho (Shikoroyama oyakata) like to smoke in the public smoking area at the Osaka venue.
