'The Detective Who Lost His Memory,' an immersive mystery event produced by Creators Next Co., Ltd. (CEO: Nozomu Kubota) and featuring popular voice actor Nobuhiko Okamoto, will be held in Nishikawa Town, Yamagata Prefecture, starting Sunday, April 26, 2026.
Participants will act as detectives, touring the town by bus and using their deductive skills and teamwork to solve a difficult case that occurred in Nishikawa. The town, acting as the organizer, did not conduct any traditional advertising, instead utilizing an 'ARG (Alternate Reality Game)' approach. By playing a mysterious online game, participants are led to discover the strange events unfolding in Nishikawa, effectively reaching mystery fans nationwide.
The mysterious online game, secretly launched via a social media account with only three followers, has already been played by over 2,000 people across the country through word of mouth. To translate this enthusiasm into real-world tourism, an 'Immersive Experience & Press Conference' for media representatives will be held on Wednesday, April 22.
