Roka-mon Gate: The Key to Protection is the Feudal Lord’s Passageway
This Yagura-mon gate (a gate with a watchtower) was located at the back gate of the main keep, with an additional floor on top of the gate that was used to intercept approaching enemies. This upper floor was also used as a passageway exclusively for the lord of the castle, connecting the main level (the castle lord’s residence) with the middle level (where feudal affairs took place), thus it was given the name Roka-mon, which translates to “corridor gate”. It was rebuilt in 1966.
