This is a First Edition April 1955 paperback book titled "Japanese Etiquette, An Introduction"
This publication was compiled by the World Fellowship Committee of the Young Women's Christian Association of Tokyo, after the end of the Post-WW2 Japanese Reconstruction era. Topics covered: Visiting and Hosting, Gifting, Dress, Tea Ceremony, and More.

The condition is very good, with only slight discoloration along the exterior. Some edge tanning is noted as this was published before the advent of acid-free paper in the 1980s. The book is wrapped in a paper slipcover that appears to be manufacturer packaging for retail sales or shipping. A partial translation of the slipcover reads in traditional Chinese "Kokuyo Paper Products Main Office"  and what looks to be a price tag for 35 Yuan. The exterior "slipcover" appears to have been stained by moisture on one side. No water damage noted on the book itself. There is a gift inscription inside the front cover dated May 1955, just 1 month after the publication's first run in April. 157 Pages.
