Earlier, Mr. Yasaburo Ikeda wrote in "Nihonbashi" in "Nihonbashi" as follows, stating that the name "Nihonbashi" was originally based on the claim that it was originally "Nihonbashi".
＞The book "Hitomoto" states, "What happened to the fact that there is Hitotsubashi and Nihonbashi (Nihonbashi) and there is no Sanbonbashi?" Nihonbashi was originally a "Nihonbashi" in the background of what is written in such a "playful word", but it is not a shame to see that the "knowledge" of the streets that people still knew at that time were hidden that one day it became Nihonbashi as a result of the same sound association. （50）
I discovered that this "Purple Ippon" is included in Volume 82, "Essays of Early Modern Era" (published in 2000) of "Full Collection of Classical Japanese Literature" (Shogakukan), so I would like to introduce the original text.
"Purple no Ippon" is an Edo geography and essay written by a Japanese scholar, Mosui Toda in the early modern period. Mosui Toda died at the age of 78 in 1706 (1706). According to the book, this book was written in 1682 (1682). It is a description of Edo's famous places according to scenic spots such as visiting castles, ancient castles, mountains, slopes, etc., and classification by landscape, and each is described in length and length. Mosui Toda seems to have been particularly interested in place names in waka poems.
In this article, "Nihonbashi" is described as follows.
＞"There is Hitotsubashi, Nihonbashi, and how is it without Mitsuhashi?" "Ichiishi Bridge, Ryogoku Bridge, and it's like without Mitsuishi Bridge" ... ... If you touch it, from Ichigoku, from Nihonbashi Edobashi, from Nihonbashi ...
(If you count, Nihonbashi is the second from Ichiishibashi in the west, and the second from Edobashi in the east, so it is a reasonable name.)
I think that Mr. Yasaburo Ikeda's claim is quite convincing.
