Sakuyalumina is an immersive, interactive entertainment experience combining fantastical light and sound, a unique story, and the natural setting of Osaka Castle Park, using cutting-edge digital art. Participants join a girl from the future named Akiyo and mysterious “Joy Spirits” on a nighttime adventure through the illuminated park to find the way back to the future. Sakuyalumina was developed by Moment Factory, an advanced digital art studio based in Montreal, Canada, known for creating original stories inspired by local culture and beautiful natural environments. The “Lumina Night Walk” first opened in Quebec, Canada in 2014, later expanding to places such as Japan and Singapore, and has received multiple international awards. This experience is described as the ninth installment in the Lumina Night Walk series and draws participants into its world as they explore the venue and enjoy a mystical journey.
