Let’s examine a map of Kan’eiji Temple and Zojoji Temple, where the tombs of the Tokugawa shoguns are situated, as well as Asakusa Shrine, Hieda Shrine, and Kanda Myojin Shrine, where the three major festivals of Edo take place.
The line connecting Kan’eiji Temple, Kanda Myojin, and Zojoji Temple with Asakusa Shrine and Hieda Shrine intersects at Edo Castle. These five temples and shrines form a protective belt-like shape across the northeast to southwest direction, which is known as the demon’s gate.
It is evident how significant these five temples and shrines were to the Tokugawa shoguns.
Please refer to the map below for the location of Edo Castle ruins.
