We've got our christmas tree up. Actually we put it up a couple of weeks ago but I just got around to putting the pictures up! As you can see, its not overwhelmingly large. It was the 200 yen 60cm tree at the Hyaku en shop. I think it'll do for our purposes, size doesn't matter.
We also got a couple of candle holders and some X-mas stockings that are tacked to the wall just above the tree!
