Creator's NEXT Inc. (CEO: Nozomu Kubota) is producing an experiential mystery event, 'The Detective Who Lost His Memory,' starring popular voice actor Nobuhiko Okamoto and set in Nishikawa Town, Yamagata Prefecture. The event is scheduled to begin on April 26, 2026. Participants will act as detectives, touring the town by bus to solve a difficult case in Nishikawa Town, relying on their deductive skills and teamwork. Nishikawa Town, the organizer, adopted an ARG (Alternate Reality Game) method, avoiding direct promotion. By playing a mysterious online game, participants are led to an inexplicable incident occurring in Nishikawa Town, attracting mystery fans nationwide. The online game, secretly launched via a social media account with only three followers, has already been played by over 8,000 people nationwide. To connect this enthusiasm to actual tourism, an 'immersive experience and press conference' for media will be held on April 22, 2026.
The project highlights three innovations:
1. **Narrative:** An online and real-world mystery experience beginning with a 'too scary name stroke count diagnosis site.'
2. **Experience:** A highly exclusive mystery experience limited to 8 participants per day, where they tour the town as detectives.
3. **Social Impact:** Utilizing empty houses and the Three Mountains Faith as tourism resources, regional revitalization through art, with collaboration from artists from Tokyo University of the Arts.
Previously, Nishikawa Town's tourism focused on skiing and mountaineering. However, a previous mystery-solving initiative in 2023 attracted over 6,000 participants and achieved a high NPS of 62. While 78% liked Nishikawa Town and 89% wanted to revisit, approximately 60% were residents of the Tohoku region. Therefore, this project aims to attract visitors from major metropolitan areas nationwide using the ARG method.
