Tower of the Sun

I visited on a weekday late morning and, luckily, was able to buy a ticket on the spot. I found the moody music and images a bit dated but absolutely worth it, if only to have the chance to see the interior structure, especially the arms. I never quite understood this tower, but became quite fond of it as the day progressed, and enjoyed seeing it as the light softened. If you can, do plan to stay into the evening to see the holiday illuminations. Tip: The route involves a climb up an interior stairway, 145 steps spread across 6 floors, and reaching just about halfway up the tower, then a descent down a different, more narrow stairwell. There is an elevator but it seems access may be by reservation.

Finally visited! I’ve been obsessed with this tower for years. You can go inside, but you MUST reserve a ticket at least a day ahead of time. There are no same-day ticket sales. Okamoto Taro’s sculptures inside are absolutely stunning

To enter inside make sure to buy your tickets a week in advance as the time slots fill up fast. Limited spacing and you're only allowed to be in the tower exhibit for 30 min. You're only allowed to take photos on the first floor but if you pay an extra fee (I think it was 800yen), you get a rental pouch for your phone allowing you to take photos everywhere. Over all there's not much to see inside. You walk up the tower and on each floor there are some sculptures that have been preserved from the '70 expo. Unless you're a fan of the artist, better suited for taking your kids, almost feels like a children's science museum.

The Tower of the Sun is an avant-garde sculpture and building created by Japanese artist Tarō Okamoto. It was known as the symbol of Expo '70 and is currently preserved and located in Expo '70 Commemorative Park in Suita - Osaka. The tower has multiple faces on its front and back representing past, present and future. It was designated a Tangible Cultural Property of Japan in 2020. (Source : Wikipedia)

Nice place especially to spend time relaxing with family. It was my first time visiting, alone, I feel like I had a flash back to 1970 when the expo was there (even I haven’t born yet at that time)

Very attractive in autumn, especially during maple season. If you want to avoid tourists and enjoy an easy stroll, this is a perfect place to visit.

The Tower of the Sun is one of Osaka’s most iconic landmarks, standing boldly at the heart of Expo ’70 Commemorative Park. Created by artist Tarō Okamoto for the 1970 World Expo, the structure still feels strikingly modern, even decades later. Its three faces—representing the past, present, and future—give it a unique symbolic presence, and its unusual form immediately captures attention. Walking around the tower, you can appreciate its massive scale and the creativity behind its design. The surrounding park provides a peaceful setting, making it easy to take your time observing the details and photographing the tower from different angles. For those interested in art, history, or architecture, the Tower of the Sun offers a fascinating blend of cultural significance and avant-garde expression. Even from the outside, it’s an inspiring piece that leaves a lasting impression on anyone visiting the Expo ’70 grounds.

Giving a 3 stars as not able to went in the Tower and seems is hard to get the reservation. The museums in the park area are some good places to visit.
