One of the most famous viewpoints in western Japan, the Yokoyama Observation Deck lies atop Mt. Yokoyama within the Ise-Shima National Park in Mie Prefecture. The deck boasts a spectacular, unobstructed view of the Ago Bay and its 60+ islands and pearl boats. There are plenty of seats available on the deck, as well as a café that serves snacks and drinks. The observation deck is accessible by car, bike, or on foot.
