The outer box shows signs of aging and yellowing. Volume 13 has a torn and creased spine. The main body of the books shows slight yellowing, but is in good condition and appears very clean. I have taken photos of Volume 1 as a sample to show the condition of the books as clearly as possible, so please take a look. Please understand that these are used books before considering a purchase. Through the Ashio Copper Mine Pollution Incident, Shozo Tanaka confronted the powerful Meiji state authority. This collection compiles the words of this unique great thinker into a 20-volume set, tracing the path of his life's thought, which led to the concept of "the revival of the destroyed Yanaka Village = the revival of Japan." ■ "Shozo Tanaka Complete Works" in 20 volumes (19 volumes + supplementary volume) Contents: Volume 1 [Autobiography] Shozo Tanaka's Old Stories / Fragments of Recollection [Essays 1] Freedom and People's Rights Volume 2 [Essays 2] Political Theory / Drafts of Diet Speeches / Ashio Copper Mine Pollution Issue (2) Volume 3 [Essays 3] Ashio Copper Mine Pollution Issue (2) / Yanaka Village Issue / Current Affairs Volume 4 [Essays 4] Yanaka / Flood Control Issue (1) / Current Affairs (2) Volume 5 [Essays 4] Yanaka / Flood Control Issue (2) / Current Affairs (3) / Miscellaneous / Supplements / Waka, Haiku, Calligraphy Volume 6 [Tochigi Prefectural Assembly Records] Prefectural Assembly Documents / Prefectural Assembly Diary Volume 7 [House of Representatives Speeches 1] From the 1st Diet to the 11th Diet Volume 8 [House of Representatives Speeches 2] From the 12th Diet to the 15th Diet Volume 9 [Diary 1] From March 19, Meiji 3 to December 4, Meiji 29 Volume 10 [Diary 2] From January 1, Meiji 31 to November 3, Meiji 38 Volume 11 [Diary 3] From June 28, Meiji 39 to December 30, Meiji 43 Volume 12 [Diary 4] From January 1, Meiji 44 to January 5, Meiji 45 Volume 13 [Diary 5] From January 5, Meiji 45 to August 2, Taisho 2 Volume 14 [Letters 1] From Meiji 2 to Meiji 31 Volume 15 [Letters 2] From January, Meiji 32 to September, Meiji 36 ...
