The Japanese word origami itself is a compound of two smaller Japanese words: "ori", meaning to fold, and "kami", meaning paper.
All of the models shown on the blog are folded by me. I will use Wikipedia to explain about origami and some meanings in this way.
Thousand origami cranes (千羽鶴 Senbazuru) is a group of one thousand origami paper cranes (鶴 tsuru) hold together by strings. An ancient Japanese legend promises that anyone who folds a thousand origami cranes will be granted a wish by a crane. Some stories believe you are granted eternal good luck, instead of just one wish, such as long life or recovery from illness or injury. This makes them popular gifts for special friends and family. The crane in Japan is one of the mystical or holy creatures (others include the dragon and the tortoise) and is said to live for a thousand years: That is why 1000 cranes are made, one for each year. In some stories it is believed that the 1000 cranes must be completed within one year and they must all be made by the person who is to make the wish at the end. Cranes that are made by that person and given away to another aren't included: All cranes must be kept by the person wishing at the end.
A thousand paper cranes are traditionally given as a wedding gift by the father, who is wishing a thousand years of happiness and prosperity upon the couple. They can also be given to a new baby for long life and good luck. Hanging them in one's home is thought to be a powerfully lucky and benevolent charm.
Several temples, including some in Tokyo and Hiroshima, have eternal flames for world peace. At these temples, school groups or individuals often donate senbazuru to add to the prayer for peace. The cranes are left exposed to the elements, slowly dissolving and becoming tattered as the wish is released. In this way they are related to the prayer flags of India and Tibet.
In Western countries, the custom has been extended from giving a senbazuru to cancer patients to using them at funerals or on the grave.
The thousand origami cranes were popularized through the story of Sadako Sasaki, a Japanese girl who was 2 years old when she was exposed to radiation from the atomic bombing of Hiroshima during World War II. Sasaki soon developed leukemia and, at age 12, inspired by the senbazuru legend, began making origami cranes with the goal of making one thousand. In a popular version of the story as told in the book Sadako and the Thousand Paper Cranes, she folded only 644 before her death; in her honor, her classmates felt sorry and agree to complete the rest for her. In an alternate version of the story, the Hiroshima Peace Memorial Museum states that she did complete the 1,000 cranes and continued past that when her wish did not come true.
After her death, Sadako's friends and schoolmates published a collection of letters in order to raise funds to build a memorial to her and all of the children who had died from the effects of the atomic bomb. In 1958, a statue of Sadako holding a golden crane was unveiled in the Hiroshima Peace Memorial Park. At the foot of the statue is a plaque that reads:
"This is our cry. This is our prayer. For Building peace in the world."
There is also a statue of her in the Seattle Peace Park. Sadako has become a leading symbol of the impact of nuclear war. Sadako is also a heroine for many girls in Japan. Her story is told in some Japanese schools on the anniversary of the Hiroshima bombing. Dedicated to Sadako, people all over Japan celebrate August 6 as the annual peace day.
In August 2012 Clifton Truman Daniel (grandson of Harry Truman) met Sadako's older brother, Masahiro Sasaki (a peace activist), to pay respect to the Hiroshima survivors.
