Sad to hear about your money issues, that's something I'm at least thankful of, that uni is almost free here in Norway. That won't be the case when (or if) I go to Japan though.
I love my warm water bottle <3 I have one stuffed inside a plushie of Winnie the Pooh ^__^
You must be careful with your back though, so you don't end up with chronic pains later on in life!

The Christmas brochure is so cute ^__^ those cakes looks like nothing you would get here where I live, but they look yummy though. Btw, it's -10 degrees here in Tromsø now, and show hehe XDDD
