Was there "giboshi" in Nakahashi?
It is a famous story that the giboshi was attached to Nihonbashi, Kyobashi and Shimbashi, which were created in 1603 (1603). The name "Nakahashi" was between "Nihonbashi" and "Kyobashi", so it was named like that, so the bridge of Nakahashi was later than the Nihonbashi Bridge. It is presumed that nine Funairi moats were built from 1612 to 1615. Was there a giboshi in Nakahashi on the Momiji River (now Yaesu Street), one of the Funairi moats on Edo Maejima? Isn't it coincidence?
The conclusion is, unfortunately, "I don't know if giboshi was there," but I would like to introduce the process of drawing such conclusions.
First, we will unravel the history of Nihonbashi Bridge. Since the average life span of wooden bridges in the Edo period is 20 years, it is true that they were rebuilt in 1618 (1618), 15 years after the construction. At this time, it is presumed that Nihonbashi-Nakahashi-Kyobashi was connected. There is no record that it was burned to a large fire for about 40 years until 1657 (1657). Around the 20th year, it was around Kanei 15 and 16 (1638, 1639), and it is said that giboshi was first hit at this time. Nakahashi may have already been built, so it may have been called around the same time as Nihonbashi and Kyobashi. Although it is not clear whether the giboshi on the Nihonbashi balustrade had existed before that, what was attached during the renovation after the Great Fire of the Meiryaku era was written as "Nihonbashi giboshi Ju" in Kyoho Senshu. However, there is no description related to Nakahashi.
The following is written in the "Takee Chronology Table" by secret order.
"One book is that it used to be a deer (?) bridge, Shiga, for the first time at this time, giboshi and so on. There is also a giboshi in the "Azuma Tour Map" of the Kanei era. At this time, it is said that a person named Katsuji Kodama will start."
According to the history of Chuo-ku, the balustrade-built Tang Copper giboshi main pillar bridge was not found in Nakahashi because it asserts that only two bridges, Nihonbashi and Kyobashi, except for Edo Castle Mitsuke Gate. Is the "grade" different from Nihonbashi and Kyobashi?
Landfill in Nakahashi
What was attached at the time of the renovation after the Great Fire of the Meiryaku era was described as "Nihonbashi giboshi" in Kyoho Senshu, so before that there was no giboshi in any bridge.
According to the Chuo-ku Historical Map, "Funairibori on Edo Maejima", the western half of the Momiji River was reclaimed from 1673 to 1681. According to the Yanbao New Year's Bill, the western half has been reclaimed and the bridge has been completely removed. On the other hand, the eastern half of the Momiji River was reclaimed from 1774 (1774) to 1846 (1845), and disappeared with the names of Nakahashi and Momiji River. I don't have any evidence like giboshi in Nihonbashi or Kyobashi, so I'm afraid I can't follow any more.
