I'm not entirely sure, but I believe this is a textbook for Noh chanting. There are pencil markings throughout, and there are also stains as shown in the photos. Please consider this item, understanding that it is old and has been stored at home for a long time. I am also selling other Noh chanting books, so if you purchase them together, I will discount the total by 200 yen. Please let me know in the comments if you are interested.
