Takahata's character Chizuko is a belly dance teacher so as preparation for the role, she lost 5kg in three weeks before the filming. As Takahata used to be from the swimming team back in school, she isn't that concerned about baring her skin nor her belly and has a nice figure despite being 62. Initially, the costumes designed for Chizuko did not show her belly but Takahata felt that it seemed odd because of her character's occupation. When it came to the costume fitting, it was then decided that instead of trying to cover up her body in an awkward manner, it would be better to be natural about revealing her body. However, in order to ensure that she won't look like an eyesore to the viewers, Takahata went jogging with a rubber belt around her tummy in the evenings as part of her diet routine.
On the other hand, Takahata rated herself a low 27 points for her belly dance performance because she couldn't get used to the music and rhythm. Although she had learnt it in the past, she couldn't continue with it as it was too difficult for her. After just one day of training, it made her back hurt so much that she couldn't walk but it was a good way of losing fat in her belly area. When asked to described her character, Takahata said that Chizuko is a rather detestable person who speaks harsh things to others and dotes on her stepson excessively.
