Total: There were 62 volumes. Even if each volume was 200 yen, it would be a great deal at 12,400 yen, and since shipping is included, it's like a 2,000 yen discount. Just to avoid any misunderstanding, This is a reconfirmation as of December 22, 2023. While there are definitely 62 volumes, Not all volumes are complete. Please refer to the images; there are some missing. In volume 1, there were originally 3 volumes included, but only 2 volumes are present. See the first image. This was from the first edition. See the third image for more details. Volumes 5, 6, 7, 11, 12, and 13 have writing in them, but it doesn't hinder reading. See the fifth image. There are some stains on the covers of the books as well as on the inside volumes, but I have judged that it does not affect reading. See the fourth image. It's from 50 years ago, and the original price was about 2,400 yen for a set of 3 volumes, so I think it would be of sufficient value for learning and research purposes, focusing on the content rather than collecting pristine copies.
