## What is the Family Puzzle-Solving Event 'Mystery Hunter'?
'Mystery Adventure Rally: Mystery Hunter' is an experiential puzzle-solving event that parents and children can participate in together.
Supported by local boards of education, it has been held in parks across the country since the fall of 2022, divided into two seasons: spring and fall. Every year, more than 100,000 family members participate.
We are pleased to announce that this highly popular puzzle-solving event will be held in Kanagawa Prefecture this spring!
Participants will take on the 'mysteries' that have suddenly appeared in the park. While searching for problems placed in various locations within the park, they will uncover the hidden mysteries.
Various series of stories unfold, such as the 'Legendary Sword Series' concerning a sword that seals a demon king, and the 'Phantom Thief VS Detective Series' chasing a stolen jewel, allowing participants to challenge different problems in each series. In addition, because you can choose from three courses based on difficulty, it can be widely enjoyed by everyone from preschool children to upper elementary school students.
The appeal is that you can deepen your learning while playing, with puzzles that interweave elements of textbook content and the SDGs.
Please join us to make memories with your family.
