A set of 6 books of All Hit Songs from Jiyu Kokumin Sha. This set includes the years 82, 83, 84, 85, 87, and 92. However, the 92 edition is in poor condition, so please consider it as a bonus. The contents include chord charts for popular songs, which I believe are valuable materials nowadays. There are stains, scratches, and age-related deterioration, but they do not interfere with reading. The 80s were the golden age of Japanese popular music. How about it for those who play those songs for the sake of learning from the past, or for those who are the generation of The Best Ten and The Top Ten?
