Yamane Suido
One of the first people to consider ikebana and photography together, I think.
This image is a scan of a printout of a scan (from the NDL) of a 1927 book caled 新時代の插花, or The New Age of Flower Arrangement. The word Yamane uses for “flower arrangement,” 插花/sōka, is closer to a Chinese term, the dictionary says it is “literary.”
I guess Some Japanese Flowers by Ogawa Kazumasa is an even earlier precursor, although it is less obviously about ikebana.
