A set of 5 paperback books from the Sarurien Sekiwa series, including "Gutara Sociology" by Shusaku Endo. These are interesting essays that overturn the image of Shusaku Endo. They are short essays that make you chuckle a little, like Koryoan Kanwa (Korya Akanwa). I'm selling them because my eyesight is poor and the print is small. Koryoan Koyuroku [First edition 2006] Koryoan Shokudoraku [First edition 2006] Koryoan Dobutsuki [First edition 2007] Gutara Sociology [First edition 2011] Koryoan Kanwa [3rd edition, March Heisei 15 (2003)] - Author: Shusaku Endo I bought these new and stored them at home. Some have been read a little. There is some discoloration and stains on the paper (see photos), and a fold on the corner of a page in one book (see photos). Please understand that these are used items before purchasing. Thank you for looking.
