During the middle of the day in Tokyo, the lighting is too flat and boring, but in the areas of higher latitude like Scotland, the lighting seems to be oblique enough to emboss the interesting aspects of woods and mountains. Your images, especially the first one, prove that.
If you didn't tweak any exposure-related parameters for these images, the meter of the now long discontinued D600 has proved to do an admirable job: the white snow is rendered correctly bright without losing the texture.
