Akaiwa Observation Deck (Teuri Island) is located on the westernmost point of the island. The platform from where visitors can take in a vista reaching to the horizon is built facing the ocean. It's like a cantilever deck. The panoramic view from here is magnificent. Akaiwa, which is the symbol of the island, is 48 meters high and it stands like a candle set in the surface of the sea. Visitors can look down at Akaiwa from the observation deck. There is a multitude of holes on the ground around the observation deck. These holes contain the nests of rhinoceros auklets. The diameter of each hole is about 20 cm.
