Kouri Ocean Tower is an observation deck on Kouri Island in Okinawa, looking out over the Kouri Bridge and the emerald sea. The observation deck restaurant serves wood-fired pizza and tower drinks. After waiting about 20 minutes at the entrance, visitors ride a self-driving cart for 7 minutes to the top, and pre-purchased QR codes are exchanged for paper tickets on site. The shell museum and souvenir shop are facilities on the lower floors of the tower.
