You think Christmas celebrations start too early in your country? So that when Christmas finally comes, you've already had enough of it? Where do you think "Season's Greetings" comes from?
Christmas is an entire season, just like spring or summer. The result is that by the time Christmas does arrive, you're already sick of it.
But at least it comes. In Japan, there is no Christmas at all, just preparation for it. Yep, all that buildup to Christmas day — decorations, lights, shopping, Christmas carols — then Christmas doesn't happen. It's as if they just called it off at the last minute. Or maybe someone kidnapped it. Perhaps North Korea, for example.
