With Prayers for Peace, 'SADAKO' Product Presented to the Pope |
On April 24, 2024, our product 'SADAKO,' imbued with prayers for peace, was presented to the Vatican, the headquarters of the Catholic Church.
'SADAKO' is a product that immortalizes the paper crane folded by Sadako Sasaki, who died at the age of 12 from the atomic bombing in Hiroshima and became the model for the 'Children's Peace Monument' in the Peace Memorial Park.
Utilizing cutting-edge digital technologies like 3D scanning and printing, in conjunction with silicone rubber molds, we've successfully achieved metalization and mass production of complex designs.
This crane was also presented to world leaders at the G7 Hiroshima Summit held in May 2023.
