The Tama & Earth EXPO is a collection of islands located on Tamagotchi Planet. It was constructed as a means to help the Tamagotchis learn more about the Earth and the different human cultures. It was released on the Tamatown web site when the Tamagotchi Connection Version 5 was released.
The EXPO is divided into five islands, known as "Pavilions". There is one general Pavilion in the center for recreation, and the other four represent a different region of the world where Tamagotchi toys are released. This includes the USA, Japan, Asia/Oceania, and European regions.
