In Japan, the New Year is spent with the family, but the Christmas is for couples... The evening of December 24 is somehow similar to the Valentine's Day, spent with the partner with a stroll along the special lighting arrangements, with a dinner at a restaurant booked in advance, with gift exchanges and maybe with the night spent at a luxury hotel, also booked well in advance (sometimes even months)...
And since the towers with observatories are also places of dating, for me a romantic Christmas in Tokyo is completed by admiring the night view in one of the observatories. And Tokyo Tower is still my favorite, even on its venerable 56th anniversary (on December 23)...
