With regard to the casting, the director Nakamura Yoshihiro commented that he had spent the longest time to date on this compared to his past projects because he needed to consider the ages, looks, images and impressions which the viewers have of them so as to achieve a balance among the 9 commoners and the woman who is a supporter of them. As Takeuchi's character is a fictitious character, Nakamura explained that he went to check on her profile on Wikipedia and noticed that she had never been in a period movie thus decided to offer her the role as one of the key reasons was that he wanted to see her with her hair bundled up as in the Edo era. The two had also recently worked on his horror movie "Zane" so Takeuchi was pleasantly surprised to be approached by Nakamura so soon after that. As for choosing Matsuda as a cold and ruthless official, Nakamura said that he had worked with Eita and Matsuda 9 years ago in his movie "Ahiru to kamo no coin locker" and noticed how Matsuda was so calm and collected on set that it sent shivers down his spine. As such, he felt that Matsuda would be suited to bring out the scary side of his character.
The movie will be shown in cinemas from 14 May 2016.
