almost the whole length of the site, there were three stations. The Expo Future Cars (CVS) track was at the north end and connected the Fish Cluster with Expo Land via five stations. Post-Exposition After the Expo was over, the site became Okinawa Commemorative National Government Park (国営沖縄記念公園), also known as Ocean Expo Park. Most of the exhibits were removed, although the Aquapolis was retained as an attraction and eventually hosted four million visitors. As years passed, the number of visitors to the Aquapolis declined and it was closed in 1993. In October 2000, the Aquapolis was towed away to Shanghai to be scrapped. The main tank of the aquarium facility that was opened at Expo was the largest indoor aquarium in the world at that time with a water volume of . After that, we continued to use the Aquarium facility used in Expo'75 and opened it as the Okinawa Ocean Expo Aquarium. The Okinawa Ocean Expo Aquarium was closed in 2002 due to aging and then reopened as Okinawa Churaumi Aquarium. The Tropical & Subtropical Arboretum were later constructed on the site.
