What’s the “Sampo” ("Take a Walk") SPIRAL SLOPE?

The SPIRAL SLOPE spans 9 levels as a continuous spiraling walkway that you can stroll up and down between the observation deck and the 1F on the east side of this tower. The walking distance from top to bottom is about 450m. The view changes as you walk so that you can enjoy the stroll relishing the expansive views. (Elevator is also available between the RF and 1F.)
At the center of the SPIRAL SLOPE, you will find the spiral slide ”cool-cool-cool” which is sure to entertain the whole way down. Also, on the walls of the slope you will be treated to huge murals depicting wishes for 2045 - 100 years after the end of World War II, creating a space unique to HIROSHIMA ORIZURU TOWER.

Special area where one can enjoy the warmth and breadth of the wooden architecture, as you stroll between floors.

Visitors can think about peace while viewing artwork created by local artists, all of whom are related to Hiroshima in one way or another.

Exciting Slide

Slide “cool-cool-cool”

In the center of the SPIRAL SLOPE, there is a spiral slide which is about 70m long.

This slide is a popular spot where everyone, from children to adults, can enjoy sliding around and around. (The slide runs continuously from the 12F to the 1F, but exiting is possible at each floor.) Use the “slide sheet” and feel the speed, sure to be an exciting experience. “Slide sheets” are only for the slide and available in two sizes, for both adults and children. The adult-sized sheets also offer the possibility of riding in pairs. After enjoying at the observation deck and 12F ORIZURU SQUARE, let’s try Slide ”cool-cool-cool”!
