Earlier, Yasaburo Ikeda stated in Nihonbashi's private diary as follows, stating that the name "Nihonbashi" was originally the basis for the claim that it was "Nihonbashi" at the beginning. I wrote.
＞The book "One Purple (Hitomoto)" states, "What happened to Hitotsubashi, Nihonbashi (Nihonbashi) and there was no Sanbonbashi?" Nihonbashi was originally "Nihonbashi" in the background of what was written as "Gigo", but it is no confusing to see that the "knowledge" of the streets that people still knew was hidden that someday it became Nihonbashi due to the same sound association. （50）
I discovered that this "Purple One" was included in the 82nd volume of "The Complete Works of Japanese Classical Literature" (Shogakukan), "The Early Modern Ages" (published in 2000), so I would like to introduce the original text etc. .
"Purple One" is an epic of Edo's geology written by Mosui Toda, a Japanese scholar of the early modern era. Mosui Toda died at the age of 78 in 1706 (1706). According to the book, this book was established in 1682 (1682). It is a description of Edo's famous places for each category of scenic spots such as visiting castles, ancient castles, mountains, slopes, etc., and each is described in length and length. Mosui Toda seems to have been particularly interested in place names in Waka.
In this context, Nihonbashi is described as follows.
＞"Hitotsubashi, Nihonbashi, what is Mitsuhashi's absence?" ... "Ichiishi Bridge, Ryogoku Bridge is like a bridge without Mitsuishi Bridge" ... ... If you touch it, from one stone, Nihonbashi Edobashi and Nihonbashiya ...
(If you count, Nihonbashi is the second from Ichiishibashi in the west, and the second from Edobashi in the east, and it is indeed a reasonable name.)
I think Mr. Yasaburo Ikeda's claim is quite persuasive.
