A paper crane made by U.S. President Barack Obama during his visit to Hiroshima in May went on display Saturday in Nagasaki, the second city hit by an American atomic bomb.
The red paper crane, one of four made by the president during his visit, will be exhibited at the Nagasaki Atomic Bomb Museum through Nov. 30, along with a reproduction of a message he wrote in a visitors' book at the Hiroshima Peace Memorial Museum.
The message reads: "We have known the agony of war. Let us now find the courage, together, to spread peace, and pursue a world without nuclear weapons."
The move came after Hiroshima Mayor Kazumi Matsui sounded out Nagasaki Mayor Tomihisa Taue in June about loaning out the items.
The Hiroshima museum initially planned to display the cranes until the end of August but has extended the period until the end of January due to their popularity among visitors.
One of the four cranes is to be loaned for an atomic bomb exhibition in Chicago in October.
