A gate where one roof covers both the main front pillars (kagamibashira) and the rear support pillars (hikaebashira). The roof was necessarily large to cover all four pillars. This is an older style gate that was eventually replaced by Koraimon gates, because it was impractical for defense. The large roof blocked the defenders vision of the outside and it actually shielded any attackers at the doors. There are very few extant examples of yakuimon gates at castles today. The second picture below is an inside view of the gate in the first picture so that you can get a better view of the structure of Yakuimon gates compared to Koraimon gates. The picture from Kakunodate Castle shows a smaller yakuimon in front of a samurai home.
