Passover is a religious celebration not a national one. Those people that follow Judaism in Japan would celebrate it.
Christmas is not celebrated by the Jews, because they do not accept Jesus as being anything more than just another human being. Only Christians celebrate Christmas, the birth of Jesus Christ.
There is no such thing as "Jewish Christmas". As Jesus plays no role whatsoever in Judaism, there is no Jewish holiday celebrating his birth.
Judaism is called Judaism.
There are no rooms in Judaism. Judaism is a religion, not a building.
