What is the type of jacket, or coat worn by Bosozoku gang members?

I mean i know they where the ones worn by Japanese Kamikaze pilots during the war, but i can't remember what they where called, or if there possible to get a hold of, the ones I'm talking about is, the long tailed type, like trench coats but that's not what there called, i want to get my hands on one if at all possible, but i can't search it because i dunno what it is called, i would appreciate any answer one my have, and please excuse any bad grammar, I'm kinda in a rush at the moment sorry. But yeah, i would appreciate any answer, remember its the coats the Bosozoku(Japanese biker gang) leader usually wore, not sure if it was just the leaders or not, but that's what i usually read.
