Participants receive a treasure map written in code and have to work out a riddled in order to find a treasure box filled with ¥1,000,000. In its third year, this interactive style treasure hunt event called Takarush! Grand Prix will be held at Odaiba’s Shiokaze Park. Use a combination of knowledge and inspiration to be the first to find the spot where the treasure map indicates. In order to enter, participants must be in a team of 2-10 people and be 20 years or older. Registration is now open so check out the website to register.
