In the vicinity of Kodemmacho Station on the Tokyo Metro Hibiya Line, there was a Temmacho prison. According to "Chuo-ku Monoshiri Encyclopedia", it was the largest prison in the Shogunate with an area of about 2,600 tsubo.
The Chuo-ku Tourism Test has also issued several problems related to this, but I found a problem in the past that would make a mistake if inadvertently. The following is the 9th question 44.

Question 44.
In Jisshi Park, located in Nihonbashikodenmacho, there is a stone monument that tells the history. So, among the following options, which is not in Jisshi Park?
A. Kiya Katsusaburo successive monuments i. Dr. Shoin Yoshida's history
C. The site of the Edo Temmacho execution site e. Monument to the end of Shoin Yoshida

If you inadvertently, you'll be mistaken. The correct answer is "U", but "U" is located at Daianrakuji Temple, just one road from Jisshi Park. It's a very close distance, so maybe "I"? There may have been somebody who thought it was. It's important to actually see and confirm on site.
