This mystery solving treasure hunt "The mystery of Tenka Gomen and the secret treasure-Who gets the treasure!" It seems that it is a 70th anniversary commemorative project sponsored by the Chuo-ku Shopping Street Federation.
I happened to be doing "stamp rally, Chuo-ku Shopping Street", and a treasure hunt booklet caught my eye and picked it up.
This is to solve the mystery written in the booklet, collect clues in the "place to go" in the city, understand the location of the treasure, and find the "keyword" of the application for prizes.
There is still a point to press the stamp rally stamp, so I decided to solve the mystery quickly and turn it around if it was near, but it was sweet. It's quite difficult, I can't solve it in a day, and after all, it takes more than a week to get to the first question.
Near the treasure place, some people were looking for a roar with a mystery solving booklet in hand, and wanted to teach, "I'm a little further ahead," but because it's a game, I passed by with an unknown face .

I was able to go to the place where I went for the first time, where I did not know without such an opportunity. It was good that it was also an exercise for my head and body. In the end, on Saturdays and Sundays here, we will spend the sightseeing and commerce festival “Chuo-ku Shopping Street stamp rally” (until November 13), “Anatenna Shop stamp rally in Chuo-ku” (already finished) and searching for treasures (until November 30). I decided to walk a lot throughout the city.
