What is the mystery-solving event "Fushigi Hunter" for parents and children?
"Mystery Solving Adventure Rally Fushigi Hunter" is an experiential mystery-solving event that parents and children can participate in together.
With the support of local boards of education, it has been held in parks nationwide in two seasons, spring and autumn, since autumn 2022. Each year, over 150,000 families participate.
This highly popular mystery-solving event has now been decided to be held in Miyagi Prefecture this spring as well!
Participants challenge "mysteries" that suddenly appear in the park. They walk around searching for problems installed in various places within the park, unraveling the hidden mysteries.
Various series stories unfold, such as the "Legendary Sword Series" revolving around a sword sealing the Demon King, and the "Phantom Thief vs. Detective Series" chasing stolen jewels, allowing participants to challenge different problems for each series. Additionally, there are three difficulty levels to choose from, making it enjoyable for a wide range of ages, from preschoolers to upper elementary school students.
Another charm is that learning can be deepened through play with mystery-solving that incorporates textbook content and SDGs elements.
Please join us to create memories with your family.
