It was created when the Gold Tower was reopened on March 20, 2020.
The observatory is an aerial aquarium named "Sorakin" and has a three-story structure.
The upper second floor is a combination of an aquarium and an observatory, with goldfish swimming in the windows and a view of the outside behind them.
The first floor is completely an observatory, where you can relax and enjoy the night view.
You can see the Great Seto Bridge floating in the Seto Inland Sea during the day, and the illuminated Great Seto Bridge and the night view of Marugame City at night.
