I don't see that at all. The modern "Japanese" and "barbarian" archetypes/stereotypes are kind of mutually exclusive. Sure, Klingons are about honor, but they are also about barely restrained anger, rather than personal discipline. Worf, specifically, may be like a Samurai, but not the rest of the Klingons.
Not in Hollywoodland. Picture this, what if we make the Klingons all honor focussed and stuff, like the Japanese, and get this, we twist that stereotype by making them be barbaric as well!
