The Japanese envelope paper size, as we know it today, evolved during this period, reflecting the aesthetic and functional needs of the time.

Culturally, paper has always held significant importance in Japan. It is a symbol of purity, elegance, and simplicity. The Japanese envelope paper size, with its unique dimensions and aesthetic appeal, embodies these cultural values.

It is often used for formal correspondence, reflecting the Japanese emphasis on politeness and respect in communication.
One of the unique features of the Chūō-gami is its ability to be folded in various ways to create different envelope styles. This versatility is a testament to the Japanese appreciation for the art of paper folding, or origami.
