The director, Tatsuya Mori, first learned of this incident through a small newspaper article about a movement to establish a memorial to the victims. However, he had difficulty finding records on the details of the incident. The contemporary president of the neighborhood association that the victims came from speculated that the six surviving members may have avoided speaking out about the incident, as they felt that they would have been ignored as burakumin. However, the president also expressed apprehension about the film, and said "Digging up the incident might lead to younger generations experiencing discrimination against our community once again. We don't want our children to experience the discrimination we went through".^[4]

Mori described his motivation as follows:^[1]

In modern Japan, I think there is a strong and growing tendency to look away from our negative history. But I believe that people grow up by remembering their mistakes.

They had difficulty raising funds for the film due to its subject matter, but eventually managed to raise 35 million yen ($253,000) through a crowdfunding campaign. They also had difficulty with casting, as talent agencies often avoid having their actors appear in controversial films. In spite of this, well-known actors, including Rena Tanaka and Arata Iura, ended up appearing in the film. Tanaka stated that she was motivated to participate in the film due to parallels that she felt between the murders and events in the contemporary Russian invasion of Ukraine. Iura admired Mori's goals for creating the film, and had already acted in films with strong social messages before.^[1]

Principal photography for the film began on August 20, 2022, and lasted until mid-September. Shooting took place mainly in Kyoto and Shiga prefectures.^[1]
