I believe this is a booklet distributed at school. It summarizes the essence of etiquette and manners, and might be helpful for adults to read. Please understand that the name on the back cover has been blacked out. Also, there is some slight creasing. When purchasing, please check the photos and understand that this is a used item stored at home before making your purchase. Note: Pages 35 and 61 contain explanations of "Edo shigusa," which are described as manners passed down from the Edo period. However, "Edo shigusa" did not exist in the Edo period and was a fictional creation by a person named Sanko Shiba in the 1980s, so it's best to ignore this column.
