Nihonbashi Scavenger Hunt Adventure

The Tale of the Undersea Palace

Explore Nihonbashi in a whole new way!


Once upon a time….

In the metropolis of Tokyo, there was a famous bridge known as Nihonbashi.
One day, near that bridge, on the banks of the river,
as you were enjoying a stroll, you came upon a strange sight:
a giant turtle pulled itself out of the water and started to come closer to you.”Don’t be afraid”, it said. “I am a messenger from the Undersea Kingdom. We are in danger and in need of your assistance.

Can you help us? You are known for your puzzle-solving skills, and in order to save our beautiful kingdom, you must pass a number of challenges. If you agree to this quest, you will save not only our world but yours as well. Your first challenge is to find the scroll….to save the future you must start with the past.”

With that, the turtle disappeared, and so your journey begins.

The rest of your story will unfold in the following pages…
