What is the date of Christmas in Japan?

Answer 1

In Japan, the shops are covered with decorations from early Dec, on the 24th of Dec people "celebrate" Xmas by eating chicken and cream cake with strawberries and then on the 25th they take down all the decorations and put up the new year ones.

Apart from the small minority of Christians (who usually celebrate on the nearest Sunday to the 25th) in as much as any one does anything for Xmas it is the 24th of Dec that people celebrate.
