Simply from appearances, it's really hard to tell they are actually Japanese. With fluent Chinese and good service, they did impress many visitors.

Nagao Banriko was a volunteer at the Aichi Expo in Japan four years ago. And as a student  learning Chinese in Beijing, she signed up to volunteer this time.

Altogether 75 Japanese volunteers, aged from 20 to 66-years-old have been selected to come to the Expo...and half of them can speak Chinese.
