Osaka aquarium
Osaka Aquarium is the largest aquarium in the world, covering an area of 26,570 square meters and having 2.9 million gallons of water. The surrounding buildings have the theme of ring of fire, which means that volcanoes surround the Pacific Ocean. The tour starts with the video of volcanic eruption, and then take the elevator to the eighth floor. Walking down the spiral stairs, you will experience 14 different living environments, from the Arctic to the tropics, from the daytime world to the Japanese jungle, and then from the surface of the Arctic to the Antarctic, as well as Monterey Bay, the Great Barrier Reef and other ecosystems that make you feel like you are at the bottom of the sea.
