The Shihan of Sosui****su-ryu is Monzo ****ama of Fukuoka. He's a construction worker and teaches judo.
Most of that was eaten up by the profanity checker, probably.
(Alternate spellings follow)
Sosuishi-ryu is the family style of the Shiitamas, handed down father to son (or son in law) since 1650. To an extent, Shiitama-sensei defines the style. In feudal form, he has total authority on doctrine and legitimacy. I've never heard of him exercising it- the political infighting and crap seems to be limited to the NY faction.
