What is the parent-child puzzle-solving event "Mystery Hunter"? "Mystery-Solving Adventure Rally: Mystery Hunter" is an experiential puzzle-solving event that parents and children can participate in together. Backed by local boards of education, it has been held in parks nationwide in two seasons, spring and fall, since autumn 2022. More than 150,000 families participate every year. This highly acclaimed puzzle-solving event will be held in Tokyo this spring! Participants will challenge "mysteries" that suddenly appear in the park. By searching for questions placed in various locations within the park, they will uncover the hidden mysteries. Various series of stories unfold, such as the "Legendary Sword Series" surrounding a sword that seals the demon king, and the "Phantom Thief VS Detective Series" chasing stolen jewels, allowing participants to challenge different problems for each series. In addition, since you can choose from three courses categorized by difficulty, a wide range of ages from preschool children to upper elementary school students can enjoy it. The appeal is that you can deepen your learning while playing, with puzzle-solving that intertwines elements of textbook contents and SDGs. Please join us to create memories with your family.
