Here's a photo of the moat and the surroundings of Matsumoto Castle, taken from one of the small windows of the main donjon. I love that bridge painted in vermillion, perfectly harmonized with the black color of the castle and also with the emerald color of the water. And in the background, you can see the snowy peaks of the Japanese Alps.
