"Tatsukawa Bunko" series and its similar follower (summary)
Lecturer: Katsuya Yoshimaru
At this lecture, we explained the clothbound 'Kodanbon', like "Tatsukawa Bunko" series, which were published a lot in Taisho period. This type of books sized 12.5 by 9 centimeters came to the market around 1911. Even its size was smaller than the one for octavo book, which meant that you could print more characters in it. As the "Tatsukawa Bunko" series were quite successful, other publishers also followed the trend. This trend caused oversupply and coarse goods for the market though. Therefore this type of books were published less after 1917 and around. In the early Showa period
Kodan books with a color-supplement cover in A6 size took over of the clothbound one.
Regarding the studies about "Tatsukawa Bunko" after "Tatsukawa Bunko no Eiyu tachi (Hero in Tatsukawa Bunko)"-by Kenichi Adachi- was published by Bunwa Shobo in 1980, Nanryo Kyokudo the fourth carried out its bibliographic studies.
By the support of his research, its chronological table of publication became more detailed, and the system for replacement was also confirmed "a used book exchanged with an old-styled book + 3 Sen", instead of "a new book exchanged with an old-styled book + 3 Sen". Also, the theory, that Gyokushusai Tamada had created Sasuke Sarutobi as his original character, was corrected by the research of Nanryo Kyokudo, Keiichi Takahashi etc. Additionally, the "Onna mon" (by Ranko Ikeda / Kawade Shobo Shinsha/1960) has been valued as basis for the theory. It turns out though that some facts in the "Onna mon" (by Ranko Ikeda / Kawade Shobo Shinsha/1960) can't be true.Therefore we explained that there's a room for doubt when it comes to the theory that Gyokushusai Tamada selected Songoku as a model for Sasuke Sarutobi.
