What was Sony’s celebration?
Sony organized a Japan-only campaign around the film, running June 28 through August 18, 2025. It is over, so the campaign’s lottery prizes and events are not current offers.
A campaign spanning Sony businesses
Sony Group said 10 of its companies participated and the campaign appeared across more than 56 touchpoints, including websites, social media and newsletters. Participants included Aniplex, Sony Music Entertainment (Japan), Sony Interactive Entertainment, Sony Corporation, Sony Marketing, Sony Life Insurance, Sony Assurance, Sony Bank and S.RIDE.

- Tanjiro Kamado, joined with Inosuke Hashibira, a boy raised by boars who wears a boar's head, and Zenitsu Agatsuma, a scared boy who reveals his true power when he sleeps, board the Infinity Train on a new mission with the Fire Pillar, Kyojuro Rengoku, to defeat a demon who has been tormenting the people and killing the demon slayers who oppose it!
The campaign invited fans to enter a lottery for items such as posters, character figures and Sony products. Examples included theater posters signed by Japanese voice cast members, PlayStation 5 consoles signed by theme-song artists Aimer and LiSA, and WF-1000XM5 headphones with their signatures on the packaging. Sony’s campaign site also featured a playlist of theme songs and soundtrack selections, information about Demon Slayer -Kimetsu no Yaiba- The Hinokami Chronicles 2, Sony Store events and photographs of special taxis offered through S.RIDE.
Sony campaign planning lead Yusuke Takeno described the aim as letting fans “enjoy Demon Slayer: Kimetsu no Yaiba to the fullest through film, music, and games.” The campaign brought several entertainment and consumer businesses together rather than centering on a single promotional event.
