One suitcase. A series of clues.
A team that needs to work together.

What is Suitase Mystery?
Suitcase Mystery is a hands-on team-building challenge where participants work together to unlock a suitcase by solving a series of interconnected clues and puzzles.
Teams examine the materials they find, share discoveries, test ideas, and decide which clues will move them closer to the solution before time runs out.
No single person has all the answers.
Progress depends on participants communicating, listening to different ideas, sharing information, and combining what they know.
For bilingual groups, Japanese and English speakers can receive different pieces of information. Neither side has the complete picture, creating a natural reason to communicate across languages and work toward the same goal.
Is Suitcase Mystery Right for Your Event?
Suitcase Mystery is a good fit when you want participants doing more than simply sharing the same room. The challenge gives people a clear reason to communicate, exchange ideas, and work toward something together.
