Do you think all Japanese people have straight hair? It seems like many people believe that Asian people including Japanese have straight hair only.
It’s not right – actually some people in Japan (I don’t know about other Asians) have wavy/curly hair. We call those, “kusege (wavy hair),” and “tennen-parma (curly hair).”
Interestingly, although there are many people who have wavy/curly hair, many schools in Japan have a rule that students can’t have their hair curled. I remember that one of my classmates who has remarkable curly hair had to bring a letter from her parents to let her teacher know that she has natural curly hair so that she is not against the rule. Well, I hope there is no such rule anymore.
