There are places in Japan that sometimes become castles in the sky. That is Echizen Ono Castle in Fukui Prefecture. This castle was built around 1576 during the Warring States period. I was able to shoot with a DJI drone on the best day when the sea of clouds occurred. The scene was like it used to be. When I was finally able to shoot after going through many times, my hands trembled and I cried. It is unusual to be able to take this picture in Japan. Please add it to your collection.
