History of term “taiko” in literature
Google has a fun tool to search through their catalogue of scanned books called the “Ngram Viewer“. The viewer allows users to search for the occurrence of a term or terms in approximately 5,000,000 books from 1800 to 2000. The term “taiko” gives the following, for example.
I’m guessing the spike in the 1960s coincides with the publication of Taiko: An Epic Novel of War and Glory in Feudal Japan by Eiji Yoshikawa (“taiko” also means “great ruler”), but who knows… could it be the influence of Osuwa and Sukeroku?!
Here is a TED video about the project by some of its contributors. Have fun!
