The members of the Unity Club joined the fundraising campaign centered around the Hiroshima Society of School Children for Building World Peace. On April 1 that year, they issued a prospectus to schools in Japan asking for donations, and the campaign moved into full gear. Because the campaign had already been introduced in newspapers, on the radio, etc., the prospectus quickly garnered responses from schools around the country. About a year after Sadako's death, in October it was decided to erect the statue in Peace Memorial Park. Now it was definite—the statue would be built.

On May 5, 1958, the Children's Peace Monument was unveiled in Peace Memorial Park. Elementary, junior high, and high school students in Hiroshima and around the country were invited, and a total of about 500 people participated, including Sadako's family.
Two and a half year had gone by after the start of the statue movement.
Each with her or his own thoughts and emotions, people gazed at the statue completed through the efforts and goodwill of so many. One of Sadako's classmates-the wellspring of the movement-said that, to her, the statue was Sadako herself.
The Children's Peace Monument stands nine meters tall. The pedestal has three legs, and standing on the top of that pedestal is a "young girl holding a paper crane high over her head." The bronze figures of another girl and a boy decorate the sides of the pedestal. The design of this monument is extremely impressive and became one of the symbolic monuments in Peace Memorial Park.
