門の上に敵を迎え撃つための上屋があります。上屋は本段の御殿（城主の住居）と一段低い中の段の表書院（政治の場）を結ぶ渡り廊下とつながり、城主専用の廊下として使われたため廊下門と呼ばれていました。昭和41年（1966）に再建されました。

　This gate had an additional floor on top that was used to intercept approaching enemies. And it was connected to a passageway between the Goten (the castle lord’s residence) on the main level and the Omote-shoin (place of feudal affairs) on the middle level one level lower. This floor was also used as a passageway exclusively for the lord of the castle, thus it was given the name Roka-mon, which translates to “corridor gate”. It was rebuilt in 1966.

문 위에서 적을 공격하기 위한 우와야(上屋)가 있습니다. 우와야는 혼단의 고텐(성주 주거지)과 1단 낮은 중간 단의 오모테쇼인(정치의 장)을 잇는 복도와 이어져 이는 성주 전용 복도로서도 사용되었기 때문에 로카몬(廊下門)이라고 불렸습니다. 1966년에 재건되었습니다.
