Sources: 8. Developments: 3. Promotional activities for the Japanese mystery drama “White Swan and Bat,” a live-action adaptation of Keigo Higashino’s novel, have intensified ahead of its September 4 release. Initial promotion included the release of nine new scene photographs featuring lead actors Hokuto Matsumura and Mio Imada. These images depict tense moments between the characters, illustrating the film’s central investigation into the murder of lawyer Shiroishi Kensuke and the subsequent doubts raised by the children of the suspect and the victim. Following the release of these images, Matsumura and Imada attended a promotional event in Tokyo near the Sumida River. Dressed in traditional yukata, the actors discussed the film’s themes of moral ambiguity and the “grey areas” of human emotion. The promotional campaign has since expanded to include interviews on various Japanese television programs. During a recent promotional event in Tokyo, it was revealed that the original author, Keigo Higashino, who passed away last month, had viewed a screening of the completed film. Higashino reportedly praised the final scene to producers. Matsumura and Imada expressed deep gratitude toward the late author, noting that his approval provided a sense of relief and honor. Additionally, Matsumura drew attention for his new orange hair color during a live appearance on the morning program ‘ZIP!’ as part of the final push before the premiere. ## Timeline ### 2026-09-03: Hokuto Matsumura and Mio Imada promote film ‘Swan and Bat’ Actors Hokuto Matsumura and Mio Imada promoted the film ‘Swan and Bat’, revealing that late author Keigo Higashino viewed and praised the completed work before his passing. 8 sources. https://clstr.news/cluster/hokuto-matsumura-and-mio-imada-promote-film-swan-and-bat ### 2026-08-20: Hokuto Matsumura and Mio Imada promote film ‘Swan and the Bat’ Hokuto Matsumura and Mio Imada appeared in yukata at a promotional event for the mystery film ‘Swan and the Bat’, based on the novel by Keigo Higashino, ahead of its September release. 2 sources. https://clstr.news/cluster/hokuto-matsumura-and-mio-imada-promote-film-swan-and-the-bat ### 2026-07-22: New promotional photos unveiled for Japanese film “White Swan and Bat” Nine new promotional photos for the Japanese mystery film “White Swan and Bat,” starring Hokuto Matsumura and Mio Imada, reveal tense scenes about a lawyer’s murder and its aftermath.
