Hojo-Jitsu Any practioners?

[Humble Novice]

I already posted this on the Chinese forum, then realized this was Japanese.

 

So I'll post it on this forum. Has anyone ever taken or even heard of Hojo-Jitsu. It's a japanese martial art based on tying someone with rope. It was historically used for the samurai and japanese police to secure prisoners that were wanted alive. (interrogation and prisoner exchange purposes I would surmise)

 

I'm curious if anyone's taken it, because it would seem useful for winning bets (hey, I bet I could tie you up? Ten bucks says you couldn't) or dealing with little brothers (I'm warning you, if you don't go away I'll tie you up)

 

Just wanted to see if anyone took it. And if so, what the basic principles are.
