Orizuru Tower
Orizuru Tower is a 14-storey building beside the Atomic Bomb Dome with a rooftop deck that looks straight down on the Dome and across Peace Memorial Park. Adults paid ¥2,200 in October 2026. Inside, you can fold a paper crane and drop it into the glass Orizuru Wall. It is a private attraction, not part of the memorial.
Orizuru Tower is the 14-storey building across the street from the Atomic Bomb Dome, and its rooftop deck gives the best view of the Dome from above. An adult ticket cost ¥2,200 in October 2026, and the tower’s site gave its regular hours as 10:00 to 18:00. Inside, you can fold a paper crane and drop it into the Orizuru Wall, and walk down a wooden spiral slope. It is a privately run attraction next to the memorial, not part of it.
What the tower is
The building at 1-2-1 Otemachi completed a renovation in September 2016, with Sambuichi Architects as chief designer. It has 14 floors above ground and two below, and stands 51.5 m tall. Floors 3 to 11 are still offices. Visitors use the ground floor, the 12th floor and the roof.
Orizuru is the Japanese word for a folded paper crane.
What you can see and do
The rooftop deck
The observation deck on the roof is called Hiroshima Hill. Directly below is the Dome. From here you see the steel frame of its dome from above and can look into the ruin, which the fence at ground level does not allow. Beyond it are the Motoyasu River, the T-shaped Aioi Bridge and the full length of Peace Memorial Park. On clear days the tower says you can see Mt Misen on Miyajima.
The Orizuru Wall
On the 12th floor, Orizuru Square has digital displays about paper cranes and the Orizuru Wall, where visitors drop cranes they have folded. Dropping a crane costs ¥100.
This is a different thing from offering cranes at the Children’s Peace Monument in the park, which is free and part of the memorial.
The spiral slope
The Sampo Spiral Slope is a wooden walkway that winds down nine levels on the east side of the building, about 450 m from top to bottom. Its walls carry murals by artists from Hiroshima, made for a project called 2045 Nine Hopes, about their wishes for 2045, a hundred years after the end of the war. There is a lift if you would rather not walk.
In the middle of the slope is a spiral slide about 70 m long, from the 12th floor to the ground, for ages 6 and up with a helmet.
The ground floor
The first floor has a souvenir shop with Hiroshima products, a café, and a branch of the okonomiyaki restaurant Mitchan Sohonten. From April to October 2026 a rooftop café and bar also ran on the deck.

House rules
Children 11 and under must be with an adult. Tripods are not allowed, nor is food or drink brought in from outside. Large bags may be refused at the gate; there are paid coin lockers by the entrance on the first floor. Assistance dogs are welcome; other pets are not.
Is it worth it?
That depends on your budget and your time. The ticket costs more than ten times the Peace Memorial Museum’s ¥200, and the museum is where you learn what happened here. If you can only do one, do the museum.
But the view adds something the ground cannot. From the roof the Dome’s ruin reads as a whole building, and you see how close it stands to the hypocentre, the park and the river. Going up after the museum, when you know what you are looking at, makes the most of it. Arrive before the 17:30 last entry.
Getting there
The tower is directly east of the Dome, across the street. The Genbaku Dome-mae tram stop is a minute’s walk away; from Hiroshima Station the tram takes 15 to 20 minutes. See how to get to the Atomic Bomb Dome. The hypocentre marker at Shima Hospital is about 120 m to the south.
