Orizuru Tower

In short

Orizuru Tower is a facility that opened in 2016 adjacent to the Atomic Bomb Dome. Themed around the paper crane (orizuru), a symbol of prayers for peace, it was created by extensively renovating what was originally an office building for Hiroshima Mazda, with a design by the office of architect Sambuichi Hiroshi.

• ​Rooftop observation deck "Hiroshima Hills"​​: From a wooden-deck observation platform with no window glass, you can look out over the Atomic Bomb Dome, Peace Memorial Park, and the Hiroshima cityscape below. On clear days, it is sometimes possible to see as far as Mt. Misen on Miyajima, about 22 kilometers away
• ​Orizuru Square and the "Orizuru Wall"​​: On the 12th floor, you can fold a paper crane using special paper and drop it into the "Orizuru Wall," a glass enclosure approximately 50 meters tall. In the approximately 10 years since its opening, more than 1.33 million cranes have been contributed
• ​Sampo Slope​​: A gentle spiral ramp connecting the 1st floor to the rooftop, with a slide approximately 70 meters in total length at its center

History and Highlights

​Orizuru Tower​ is a facility that opened in 2016 adjacent to the Atomic Bomb Dome. Originally an office building for Hiroshima Mazda, it underwent extensive renovations designed by the office of architect Sambuichi Hiroshi. Floors 3 through 11 remain offices today, while the 1st floor, 12th floor, and rooftop are accessible to visitors.

The tower is themed around the paper crane (orizuru), a symbol of prayers for peace. Standing right beside the Atomic Bomb Dome, the rooftop offers a view looking down onto the Atomic Bomb Dome and Peace Memorial Park. It is a spot where you can overlook the entire Peace Memorial Park area from a different perspective than walking on the ground.

Viewing and Experience Highlights

• ​Rooftop Observation Deck "Hiroshima Hills"​​: A wooden-deck observation platform with no window glass. While feeling the breeze, you can look out over the Atomic Bomb Dome, Peace Memorial Park, and the Hiroshima cityscape below. On clear days, it is sometimes possible to see all the way to Mt. Misen on Miyajima, located about 22 kilometers away.
• ​Orizuru Square and the "Orizuru Wall"​​: At "Orizuru Square" on the 12th floor, you can fold a paper crane using special paper and drop it into the "Orizuru Wall." The wall is a glass enclosure approximately 50 meters tall along the side of the tower; the deposited cranes fall and stack up, gradually building up the wall. In the approximately 10 years since its opening, more than 1.33 million cranes have been contributed.
• ​Sampo Slope​​: A gentle spiral ramp connecting the 1st floor to the rooftop. In this wood-wrapped space, you can walk up and down while reflecting on the history of Hiroshima. At the center of the slope is a slide approximately 70 meters in total length called "Kuru Kuru Cool," which you can slide down. The walls of the slope also feature "2045 NINE HOPES," wall art created by nine artists with ties to Hiroshima.

Tips for Exploring

The 1st floor houses a souvenir shop featuring Hiroshima sweets, general merchandise, famous local sakes, and more, as well as a café. Taking in the panoramic view from the rooftop before walking around the Atomic Bomb Dome and Peace Memorial Park makes it easier to understand the layout and positional relationship of each site.
