Joban Bridge, Tokiwa Bridge, and Shin-Tokiwa Bridge
On the west side of the Bank of Japan, there is a pedestrian bridge called Tokiwa Bridge, which passes the Nihonbashi River. If you write in kanji, "Jobanbashi". One downstream of Joban Bridge, there is also a bridge called Tokiwa Bridge, which is written as Tokiwa Bridge. In addition, there is a bridge called "Shin Tokiwa Bridge" upstream of Joban Bridge, which is written as "Shin Tokiwa Bridge". "Tokiwa" and "Tokiwa". It's confusing.
Jobanbashi
The main pillar is engraved with the word "Jobanbashi".
One downstream bridge is the Tokiwa Bridge.
One upstream bridge is the Shin-Tokiwa Bridge.
Jobanbashi is a bridge built over Tokiwa Bridge Gomon, the former main gate of Edo Castle. The current Jobanbashi was built in 1877 using the stone wall of the Koishikawa Gomon, which was dismantled in the Meiji era. It is said that the reason why "Joban" of "stone" was used as the name of the bridge is because the "Tokiwa" of "plate" was broken and has poor luck. However, even though the gate is "Tokiwa", it is not easy to understand that only the bridge is "Tokiwa". I doubt that one of the "Tokiwa" was a typographical error and the reason was later. If anyone knows the supporting historical materials, I would like to tell you.
By the way, when you check "Tokiwabashi Gomon" on an old map, the Owariya version cut-out picture "Omawanai Daimyokoji pictorial map (1849 / 1849)" is written as "Tokiwa Bridge Gomon" in "Nihonbashi Kita Uchikanda Ryogoku Hamacho 1850 Years" (1850 years). On the other hand, the Oomiya version of the cut-out picture "Tatsunoguchibe Map of Ondaikoji (1849 / 1849)" and "Nihonbashi Kitakami Tanabe Noe Map of (1850 / 1850)" are both "Jobanbashi Gomon". It is written.
At Jobanbashi Higashizume, there is the Nihonbashi River Tokiwa Bridge Disaster Prevention Pier. To the end of Joban Bridge from the Chuo-ku side to the Chiyoda-ku side, there is a stone monument of Tokiwa Bridge, a historic site Tokiwa Bridge, which has been maintained at the site of Tokiwa Bridge Gate. In Tokiwa Bridge Park, there is a stone wall at the time when the Tokiwa Bridge gate was placed, and a bronze statue of Eiichi Shibusawa, the face of the next 10,000 yen bill, stands.
The dock is Tokiwa Bridge.
The stone monument is also the Tokiwa Bridge.
The park is also called Tokiwa Bridge.
In Tokiwa Bridge Park, there is a statue of Eiichi Shibusawa Okina.
In the novel of the era, Jobanbashi (Tokiwa Bridge in the work) appeared in Shuhei Fujisawa's book, a bouncer Hizukisho (Shinchosha). The main character, Hachiro Ao Emata, undertakes a bouncy of Satomori Ogasawara, an old man who has a mansion in the gate of Tokiwa Bridge. Apart from that, Hachiro is asked by a monkey woman to expose Sado Mamoru's embarrassment, assuming that Sado Mamoru is embarrassed to go out. What is the reason why Mamoru Sado goes out?
