While it is called "hour", it doesn't lasts that long (actually it has to do with the sun's altitude - in Japan is about 10-15 minutes), so when I want to take such a picture I stroll around a little bit, to be prepared when the moment comes...
This was the case in Yokohama, when I saw the Minato Mirai Pukari Pier. During daylight, the building captured my attention with its beautiful western style architecture, but I realized that in the harsh light some details will be lost. So, I came back in the evening and I took this picture when the golden hour was almost finished. The sky was beautiful, the green roof was shining and the clock light was almost magic...
