Japanese family relationships have never been simple.
For children, the first lesson in complications begins with the all-important question of what to call their parents.
Kids in other countries don't seem to have that problem -- in France, it's "Papa" and "Maman," and in America it's "Dad" and "Mom," without a whole lot of change or variation. But over on this Pacific archipelago, what to call your parents changes according to generation, gender and age group.
