Then just the other day, I was assisting an English class when I saw the teacher draw an interesting picture next to an important grammatical point: The drawing was a spiral, with a sort of fluffy petal pattern surrounding it. It looked so terribly familiar, but where on earth did I see that before…?
I asked some teachers later what this symbol was, using some Japanese and a notepad to draw the image. They responded, “It is hanamaru.” Apparently kids in Japan learn this symbol from a very early age, and “It means very very good.”
Another one to add to the likes of henonenomoheji and komejirushi (※).
