Azuchi Castle Ruins It is Azuchi Castle, which Oda Nobunaga built as a base for the unification of the world and made it his own residence. It was destroyed by fire shortly after Nobunaga's death. It is a paving stone that remains in the ruins of the castle tower of Azuchi Castle. Is it because of the raging fire that it is turning red? I remember wiping my sweat off the steep slope with high steps, and the rain-soaked shore of Lake Biwa, which Nobunaga must have seen, was also impressive. Anyway, I saw "The Dream of the Strong" and felt the impermanence of all things.
