<P> Despite a rumour about Takako Fuji reprising her role as Kayako in this crossover, the actress stated several times on Twitter that she was not playing this representation of the character . Masaki Saisho, who played Kayako in Ju - On: The Beginning of the End and Ju - On: The Final Curse, does not appear in the film either . This makes Runa Endo, the fifth actress to play Kayako (counting Aiko Horiuchi, who starred in The Grudge 3 and Anna Moon in Tales from the Grudge). </P> <P> As for Sadako, Elly Nanami is the seventh actress to play the role, after Rie Inō (Ring, Ring 2), Hinako Saeki (Rasen), Ayane Miura (Ring: Kanzenban), Tae Kimura (Ring: The Final Chapter, Rasen), Yukie Nakama (Ring 0: Birthday) and Ai Hashimoto (Sadako 3D) (excluding Samara Morgan's and Park Eun - Suh's incarnations from The Ring and The Ring Virus respectively). </P> <P> The film's theme song is "Noroi no Shananana" (呪い の シャ ・ ナ ・ ナ ・ ナ) by the heavy metal band Seikima - II . It was released as part of a double A-side single on June 15, 2016, which also included an English - language version of the song . </P> <P> A certain number of events were held for the promotion of the movie . On Twitter, users can vote for either Sadako or Kayako as their favorite horror icon . The end of the vote was scheduled for the 17th of June . Two videos, one for Sadako and one for Kayako and Toshio, were uploaded on YouTube to appeal on the voters . Sadako won . In the end of May, a press conference was held to promote the movie . As it happened before for previous Ju - on movies, Sadako, Kayako and Toshio were present, in costumes, and stayed true to their roles . In the beginning of June, a baseball match featuring the Nippon - Ham Fighters and the Yakult Swallows was interrupted by Sadako, Kayako and Toshio who staged the first pit ceremony . A couple of other videos were released at the same time, featuring the ghosts of the movie teaching theater etiquette, such as not bringing recording devices or avoiding to take minors to see the movie . Social media was also heavily used to promote the movie . A Twitter account created for Sadako (as a promotion for the Sadako 3D movie) was reused . An Instagram account was created for Kayako and Toshio, depicting humorous, everyday life situation with the two ghosts . As for the marketing part, some goodies playing on the cute aspect regularly used in Japan were released, such as cup hangers, beauty masks and even a collaboration with the Hello Kitty brand . Other goodies were more traditional, such as T - shirts, key rings and doorknob hangers . </P>
