The word "japanese"

I tried to put the word "japanese" on a description of a character role. But it says "please remove profanity from the description". How is the word "japanese" is considered a profanity ? And i thought it only happened in the comment sections and the private messages section, why does the word "japanese" is considered a profane when written in a character description now ?

This happened to me often. but they didn't consider the word "japanese" a profane at the character description box before. i just hope that this problem got fixed ASAP.

Let's hope for the best
