The HIROSHIMA ORIZURU TOWER renovated by SANBUICHI Hiroshi, an architect based in Hiroshima, is definitely a remarkable addition to the city of peace. It stands next to the A-bomb Dome, formerly known as the Hiroshima Prefectural Industrial Promotion Hall designed by Jan Letzel and completed in 1915. It's now a world cultural heritage property and a reminder of the reality of the bombing and embodies the message to remember for the sake of peace for the future generations.
This ticket is for admission to the observation floor of ORIZURU Tower and ORIZURU or paper crane releasing into the glass well on the exterior wall. People fold paper cranes with the origami paper provided by buying this ticket in the air-conditioned lower floor which is accessible from the top floor or the observation floor. Both the observation floor open to the surroundings and the sealed air conditioned floor below are remarkable; in fact the whole brown building including the slope and slides just inside the outer structure is simply beautiful, sensitive, and moving. Five pieces of origami paper come with this ticket; therefore, five people can each fold a paper crane and release them. Others who do not buy this ticket still have to buy the admission ticket and it's 1700 yen - not cheap- but worth paying. Having said that, however, I hope the admission will become lower to 1000 yen.
