It was over on the 25th, as far as Japan was concerned. But not for me.
While other people dismantled their trees and carefully re-boxed baubles, I was determined to enjoy Christmas Day. That meant pulling out all the stops.
Disclaimer: most of those stops were posted over by my parents. How they knew I needed a sparkly reindeer antler headband to wear all day, I'll never guess.
I needed some help getting festive, to be fair. This has been my first Christmas away from home. And the first time I realised how much 'Christmas' as 'a thing' is shaped by my family.
I'm not religious at all - I just like presents and food. Pretty much all of us do. That said, without the little things it would've been a dull Christmas indeed. Like these selfie props:
After getting up late, downing a Bailey's coffee, dressing up, posing with bits of cardboard, and finding a Christmas party mix album, it was time to eat.
I didn't reserve a KFC party bucket, but I got my fried chicken in the end.
When I bravely trooped out in the... bright, warm sunshine... to claim my chicken, I forgot I was still wearing the antlers. The shop assistant (still dressed as Santa) duly proclaimed me 'kawaii'. I blushed a little. And then asked for an extra drumstick, just to be nice.
The chicken was surprisingly lemony and peppery. I doubt KFC would've had that nuance. Say what you like about 7-11's endless cake selection, the chicken dinner was a winner.
So was dessert.
One lucky find at the import store was a box of mini mince pies. I was so happy, I clutched them to my chest rather than put them in the shopping basket.
But I couldn't find custard, or custard powder, anywhere. That baffled me at the supermarket. A whole aisle for yoghurt... and zero custard. The evaporated milk didn't get a second glance.
Back at the house, I mentioned this tale of woe to the other Brit staying for Christmas.
"Oh, I've got custard powder. Someone sent me it."
Of all the things... and so, between us, a proper jolly British Christmas dessert was saved. More or less. As you can see, some sneaky bugger had made the mince pies with smiles on top. That detail made it a bit trickier to drown them in custard and cut their faces in half.
I went out on Boxing Day - which doesn't exist here - to walk both courses off a bit. The previously Christmassy shop windows were full of cherry blossoms. There's a metaphor in there somewhere, I'm sure.
