It does lead to the potential for people acting like a hyper-stereotypical Japanese person...but, as with any RP that one doesn't want in their sphere, it's a matter of simply ignoring it, either personally or through in-game tools, and moving on with your life.
Personally, I'm looking forward to seeing where people go with the race, particularly the Xaelan. I'm most intrigued about their lifestyle and how it shapes their demeanor, and where people will go with that.
