The traditional family time in Japan is not Christmas, which is for dating, but New Year. Families will gather together in their home towns and spend a few days doing not much at all. Mothers are included in the inactivities so the family feeds on a kind of multi-layered hamper of food to last through the break. If you're interested in snacking on metaphor laden food over the New Year, Yahachi in Subiaco will be home-delivering osechi-ryori on New Year's Eve.
