”Ote-mon” literally means the front gate. When the castle was under Sakuma Morimasaﾕs control, the Nishicho-guchi-mon gate (now called the Kuro-mon gate) was its front gate. After Maeda Toshiie entered the castle, the Osaka-mon gate became the front gate and this is what we now call the Ote-mon gate. This gate was built in the ”masugata”-style, too, and it was equipped with one of the biggest foundations for a watchtower at the castle. However, as far as we know from old records and drawings of the age, there is no evidence that this foundation ever actually had a watchtower on it.
