http://www.mangago.zone/read-manga/gokudou_darling/ (Not uke but the seme he's yakuza)
http://www.mangago.zone/read-manga/oni_ni_hatsujou/ (well the uke's neither but i thought that it'd interest you cause he's really devilish)

Also yuutsu no asa and kobi no kyoujin.. But i think that maybe you already read those (￣∇￣")

Hard to find good long yaoi manga with host and yakuza.
