I was able to get outdoors only a few days in mid-January. Fortunately, I was able to take a few photos in the last days of the traditional season, 小寒 Shōkan (Lesser cold), and the first first week of 大寒 Daikan (Greater cold).
In southern Shiga Prefecture trees display a wide variety of colors at the end of autumn in December. Some lose their leaves early, some gradually fade and lose their bright fall foliage, and some remain green throughout the year. See more photos in my Flickr photostream or one of my Flickr albums.
