Isn't it? Wouldn't know over here, it's just business as usual. Turned on the TV and didn't see a single Santa, snow flake, chrismas tree or anything to indicate it was actually christmas. Stopped in at the supermarket on the way home to pick up a few things. They have a huge tree out the front, and they've been playing christmas carols for a while now, but otherwise nothing especially christmasy, no "meli kulisumasu" katakana-english equivalent of Merry Christmas from the checkout girls or anything. Not that I feel the need to have a winge about it or anything, I don't really care, but I've been asked what christmas is like in Japan, so here's something similar to what might be an average Japanese take on christmas:
Santa-san lives in Scandanavia, or somewhere in Northern Europe.
On Christmas eve he sneaks into your bedroom while you're sleeping and leaves a present on your pillow for you.
On christmas day you can look forward to a romantic dinner with your partner, after work.
No, it's not a public holiday.
Yes, shops and businesses are open as usual.
No, they're not particularly crowded, and nor were they on Christmas eve.
I have my own Santa costume which I will don this evening to impersonate the fat happy chappy himself and try to give Tyler a little bit of fanatasy to enjoy while he's young enough to believe it. So however you spend you're day, have a nice time, and have a "beli meli kulisumasu!"
