The Tower of the Sun, created by Japanese artist Tarō Okamoto, is a funky building located in Expo Commemoration Park in Suita, Osaka Prefecture, Japan. Standing at 70 meters tall with three faces representing past, present, and future, this quirky tower was originally built for Expo '70. Visitors could explore inside during the expo, but it was closed afterward. After some deterioration and repair work, the tower reopened to the public in 2018 with new features like the "Sun of the Underworld." It's become a cool symbol of Expo '70 and a must-see for anyone visiting the park!
