Akiko: Usually when I do girls' roles, the characteristics are already made up. So when I see some parts of the character that is close to mine, I think about how I would do it.
Akiko: When I'm drinking juice and then I spill some, I go "Wa!" in Shin-chan's voice.
Akiko: I wanted to be at least 155 cm. When I go buy clothes, I have to always fix it to make it fit. It's not cheap either.
Akiko: Shin-chan is someone who I admired (looked up to). When I was going to nursery school, I was the one who always got picked on. I was always crying. But Shin-chan is different. He would never cry. So I'm a little envious of him.
