It was November 15th. I was attending a lecture on Nagoya Castle. The lecturer was Professor Miura of Hiroshima University. He is a specialist of Japanese castle architecture. The MC was Chris Glenn, who is famous as a radio DJ and samurai expert in Japan. This lecture’s theme was the gates and watch towers of Nagoya Castle.
“Okay…what does JUST six mean?” Chris noticed that Professor Miura had repeated the phrase and asked him. Professor Miura started explaining it with satisfaction…
“As I said, there are JUST six castle gates in Nagoya Castle. This number is very small. For example, Himeji Castle has 19 gates. Why does Nagoya Castle have such a small number of gates? Because it didn’t need so many gates due to each one’s strength, such as Masugata-Mon Gate.”
“Oh, yes. Death Box…” Chris nodded.
Masugata-Mon is a box-shaped gate. Once enemies entered the box, they would be shot to death by ambushing guards. No one could either move through or return alive from the gate. That is why Chris called the gate “Death Box.”
The present main gate of Nagoya Castle, which was rebuilt after the World War II, is a replica of the gate called Fujimi-Yagura from Edo Castle. But the original one was a “Death Box.” So Professor Miura was shouting, “That gate is not a part of our castle! We should rebuild the gate to its original appearance!” Yeah, he is always passionate about Nagoya Castle…
The other gates were also strong. The gate called Omote-Nino-Mon is also known as Kurogane-Mon, which means “iron gate.” It was made from iron just as the name suggests and was about 21 centimeters thick, protecting against not only bullets but also cannon balls in the Edo period. Ninomaru-Ote-Nino-Mon is a gate with a big roof. This type of gate is called Korai-Mon. Korai-Mon were excellent at preserving the construction materials against deterioration because of the weather and its unique shape was to allowed archers to shot arrows.
Therefore, the reason there were only six gates in Nagoya Castle, is each gate was much stronger than the other castles’ gates. But you might think, “But enemies can enter the castle from other places.” Actually, they could not. I’ll write about that next time.
