Taiga on Lake Biwa, February 2014.
The geese are usually quite distant here, often swimming or asleep on the wrong side of the island, fortunately this tiny Tundra Bean wandered into the foreground.

Further north into Fukui there are huge flocks of Greater White-front, especially around Sakai-cho, Fukui city and on up into Ishikawa where there are more Taiga Bean at Katano Kamo Ike. Every winter there'll be a few Lesser White-fronts to reward effort sifting through the flocks. In 2006 there was also a Swan Goose and Cackling Goose with the White-fronts. The former is rare in Japan and the latter becoming more frequent further north.
Strictly speaking Lake Shinji (Shinjiko), Shimane isn't within Kansai but it's doable as a day trip with an overnight drive from Kyoto. It's worth spending longer if possible as it's a fantastic place for birding. In the winter of 2008/09 there were many rare birds wintering in the area and one of them was Snow Goose, a species which is much easier to see further north in Japan and can't be expected in Kansai but its presence to the west shows it is at least possible.
There are always a few Black Brant on the sea in the Tsu/Matsusaka area in Mie but they are invariably rather distant.
