The “Tower of the Sun” has an, in many ways, unforgettable appearance. This building which is one of the symbols of Osaka was built as part of the 1970 World Exposition (a.k.a. Osaka Banpaku) in Suita City of Osaka Prefecture. It was left in the memorial park after the exposition ended. For almost half a century the inside of the tower was not opened to the public, until March 2018 where it was renewed and opened to public as a permanent exhibition. Our FUN! JAPAN team visited the tower to uncover the interior of the tower and its unwithering life energy over almost 50 years.
