I am confident you are on the right track, but the meaning more likely
approximates to
Etiquette, effort, courage, perseverance
That sort of list of virtues emphasized by a particular school or style
of martial arts is not uncommon.
Shonan-ryu Karate-Dou briefly had an outpost at Oklahoma State University
in the mid-1960s. Their corresponding list (in English) was
Honesty, sincerity, effort, etiquette, self-control
Cheers!
