The mystery of Kiyosugi-dori in Higashinihombashi, the course of the Tokyo Marathon 2023?
On March 5, the Tokyo Marathon 2023 will be held again this year.
The course of the Tokyo Marathon 2023 departs from the Tokyo Metropolitan Government in Shinjuku, enters Chuo-ku through Chiyoda-ku, and in Nihonbashi, Kayabacho, Ningyocho, and Hamacho from Cheongju Bridge Street to Kiyosugi Dori and Edo-dori St. I am heading to Asakusa.
I guess many people don't know Kiyosugi-dori, which is the course of the Tokyo Marathon 2023, but it's just a 400m main street connecting Cheongju Bridge Street and Edo-dori St. .
The origin of the name "Kiyosugi" and when was it made? I've been worried about it for a long time.
In the "Chuo-ku Road Nickname List" on the website of Chuo-ku, it is written that the nickname of "Kiyosugi Dori" was set in 1988, but it seems like a street that has been more old, I checked the map.
Below is a map of Tokyo City in 1934. There is the name "Kiyosugi-dori" on the street connecting Hamacho to Asakusabashi. In 1934, I found that it was already "Kiyosugi Dori". Furthermore, looking to the north side of Asakusabashi, "Kokusai-dori", which branches off from the current "Edo-dori St.", also has the name "Kiyosugi-dori". It turns out that "Edo-dori St." and "Kokusai-dori" on the north side of Asakusabashi were also "Kiyosugi-dori".
The map below is an older map of Tokyo City in 1930. It was also "Kiyosugi-dori" here.
There is no street on the map before the Great Kanto Earthquake. Therefore, after the Great Kanto Earthquake, the reconstruction road that opened in 1929 along with the bridge of Kiyosu Bridge seems to have been Kiyosugi-dori.
Kiyosugi Dori began with Cheongju Bridge, passing through the current Kiyosubashi Dori and Edo-dori St., branching north of Asakusabashi, passing through the current Kokusai Dori on the east side of Senso-ji Temple, to the current Minowa, Taito-ku, which joins Showa-dori. The confluence (end point) with Showa-dori was called "Kanasugicho (Kanasugi Shimomachi)" at that time.
I imagined that "Kiyo" in "Kiyosugi-dori" would be "Kiyosubashi (or Kiyosumi)" would be "Kiyosu", but "Cargi" was a mystery. This time, I checked the map from the early Showa era and found that "cedar" came from "cedar" in "Kanasugicho".
At present, Kiyosugi-dori is only about 400m, but it turned out that it was a street with a history that continued since the reconstruction of the earthquake.
