The Ministry of Posts and Telecommunications was founded four years after the war ended, in 1949.A shortage of materials still persisted and inflation continued. However, the Ministry promoted a mood of reform with the goal of building a new society. It replaced the cherry blossom cap badge with a badge depicting a crane with wings spread. A so-called 'special shirt,' the material for which the Ministry went to much pains to procure, had no sleeves or center back. It was a shirt consisting of only the portions that could be seen when a jacket was worn but it was the first uniform for which a necktie was required.
As the economy began recovering in 1951, the Ministry stopped referring to the trousers that the employees wore by the Japanese name 'Ko.' Their new name became 'zubon,' a loan-word based on the French word for trousers. This marked the appearance of the modern-day style.
The men's jacket had an open collar, four buttons and outer pockets on left and right sides at the breast and waist. The trousers had outer pockets on both the left and right sides in the front and on the right side at the back.
The sweltering, inefficient women's uniform was improved in 1956 and the skirt was used for the first time.
